The use of essential oils and new drug delivery systems have been considered two approaches for controlling plant pathogenic fungi. This study aimed to synthesize, characterize, and evaluate the antifungal activity of Solid Lipid Nanoparticles (SLNs) incorporating Mentha×Piperita L. Essential oil (MPE) compared to the free MPE. In the present study, the formulations of SLNs incorporating MPE (MPE-SLNs) were synthesized by high-shear homogenization and ultrasound method, and they were assessed by Z-average diameter, particle size distribution, Zeta potential, leakage stability during 6 months of storage, encapsulation efficacy, and morphological properties of the SLN formulations. The results indicated that the particle size of MPE-SLN formulations was 155.5±4.7 nm with a PDI of 0.156±0.012, a Zeta potential of -15.93±0.87 mV, and encapsulation efficacy of about 88±0.88%. They were physically stable for 6 months of storage. The results also showed that the in vitro minimum inhibition concentration for MPE on the fungal microorganisms, Rhizoctonia solani and Rhizopus stolonifer, were 2,000 and 1,000 ppm, respectively, and for MPE-SLNs it was 1,000 and 750 ppm, respectively. Therefore, the antifungal activity of MPE-SLNs was more significant than MPE, and none of the fungi were susceptible to essential oil-free SLNs. Based on the results, MPE-SLNs can be used for the safe preservation of a wide array of foods and agricultural products.

 Light is the main environmental factor for plant growth and development. Different attributes of light such as intensity, quality and duration affect plant growth and productivity. Light spectrum of growing environment is a determinant factor for plant growth and photosynthesis. The photosynthetic reactions are directly affected by various light parameters including its spectrum and intensity. Photosystem I and II (PSI and PSII) in the electron transport chain of photosynthetic apparatus are involved in converting solar energy to chemical compounds in plants. It has been found that the PSII is sensitive to light quality. Using The OJIP test, we can investigate the efficiency of various biological phases of the electron transport system. Light sources such as metal-halide, fluorescent, high-pressure sodium, neon lamps and light-emitting diode (LED) can be used for production of plants in closed environments instead of sunlight. Manipulation of the light spectrum of the lamps could trigger potential benefits by enhancing plant growth. Nowadays, by using the LED technology, it is possible to study the physiological effect of different light spectra for optimization of growth conditions and for increase the production of plants in controlled environments. This research was conducted to investigate photosynthetic apparatus, growth parameters, stomatal characteristics, transpiration rate and essential oil content of Salvia officinalis under different light spectra.
 
 In this study, the effects of different light spectra were implemented and performed as a pot experiment using soilless media in the plant growth chamber based on a completely randomized design with 6 lighting spectra including White, Blue, Red and three combinations of R and B lights (R30:B70, R50:B50 and R70:B30) with three replications. The light intensity in all growth chambers was adjusted to photosynthetic photon flux density (PPFD) of 250 ±10 μmol m-2s-1 and light spectrum were monitored using a sekonic light meter (Sekonic C-7000, Japan). Growth condition was set at 14/10 h day/night cycles, 25/22oC day/night temperatures and 40% relative humidity. Three month following plant growth under different light spectra, the plants were evaluated for their growth parameters, stomatal characteristics (stomatal length, stomatal width, pore length or aperture) transpiration rate (E), relative water content (RWC), photosynthetic apparatus (evaluation of OJIP) and essential oil content. Data analysis of variance (ANOVA) was performed using IBM SAS software (Version 9.1) and the differences between means were assessed using Duncan’s multiple range tests at p≤ 0.05.
 
 The results showed that the stomata characteristics, photosynthetic performance, growth characteristics and essential oil content of Salvia officinalis were affected by different light spectra. Increasing the ratio of red light especially combined Red and Blue lights (R70:B30) led to the improvement of growth characteristics. Transient induction of chlorophyll fluorescence showed that the highest fluorescence intensities at all OJIP steps were detected in Red light. The lowest Fv/F0 and Fv/Fm were obtained in plants grown under Red light. Occurrence of leaf epinasty and decrease in Fv/Fm indicative of phenomenon of red light syndrome in the plants under Red treatment. Red light caused a reduction in performance index per absorbed light efficiency of (PIABS) and increase in quantum energy dissipation (ΦD0), light absorption (ABS/RC) and electron trapping (TR0/RC) per reaction center. The highest Fv/F0, Fv/Fm and PIABS were obtained under combination of Red and Rlue light. The highest ΦE0 was also detected in combination of Red and Blue light. The narrow and large stomatal apertures were detected under Red and Blue light, respectively. The highest transpiration rate was achieved in plants grown under Blue light LED. Increasing the ratio of Red light resulted in reduction in transpiration rate and improvement of leaf capacity to control water loss via reducing the opening of stomata. The highest amount of essential oil (1/75% v/w) was achieved in plants exposed to combination of Red:Blue light spectra (R70:B30).
 light spectrum during plant growth can change plant metabolism, LED can be used in favor of producing good-quality food in controlled environment agriculture due to their ease of application, waveband manipulation and limited heat production. Our result showed that photosynthetic apparatus, growth parameters, stomatal characteristics, transpiration rate, relative water content and essential oil content of plants were considerably influenced by light spectra. Using OJIP test confirmed that plants grown under monochromatic Red and Blue lights were less efficient to successfully transfer the excitons and most of the absorbed energy by the photosystems was dissipated as heat. In conclusion, combined Red and Blue lights (especially R70:B30) caused favorable growth, photosynthetic functionality and maximum essential oil content of Salvia officinalis. Therefore, combination of R and B lights (R70:B30) should be considered for production of Salvia officinalis under artificial light systems during commercial controlled environment production of plants.

Fruits and vegetables are perishable due to high humidity and biological activity after harvesting (breathing, transpiration and biochemical activities). Covering fruits with antimicrobial compounds, while being edible and safe for consumers, is an effective solution to prevent the spoilage of fruits and increase their shelf life. In developing countries, packaging, storage and transportation technologies for these products have not been developed yet. One of the cheap and high-performance methods to increase the shelf life of fruit and maintain its quality during the storage period is to use a coating on the fruit. The purpose of coating application is to reduce water loss, slow aging, polish and better marketing. In addition to improving quality, coating can protect the fruit from pathogens and contamination. Edible coatings create a thin layer on the surface of the food that are effective and eco-friendly alternatives and maintain the firmness of fresh fruits and vegetables. The main components of edible coatings are natural polysaccharides, including starch, cellulose, pectin, alginates and chitosan. These coatings apply by spraying, immersion or rubbing. The use of essential oils and other extracts of medicinal plants has been evaluated in the development of edible coatings.
Adding Ziziphora tenuior L. essential oil to food has been considered as an antioxidant and antimicrobial compound. Directly use of essential oils for fruits and vegetable shelf life has some limitations due to low solubility in water, high vapor pressure and physical and chemical instability. One of the ways to reduce these limitations is the nanoencapsulation of essential oil as. Applications of nano technology to the development of edible coatings (included various nanosystems, including polymeric nanoparticles, nanoemulsions), efforts to control the release of essential oils. Aloe vera gel, which is extracted from the inner parts of the leaves, is clear, odorless, completely healthy and environmentally friendly and can replace the coverings used after harvesting fruits. This is a polysaccharide gel, it dissolves easily in water and has advantages such as preserving the aromatic substances inside the fruit, covering the wound and cuts and it is possible to add substances such as vitamins and essential oils to this gel. Due to the antibacterial properties of aloe vera, adding aloe vera gel to edible coatings can increase the antibacterial properties of this biodegradable coating. On the other hand, using nano technology can increase the efficiency, consistency and better quality of food coatings.
The aim of the present study was to prepare and produce an oral coating of nanoecapsule containing Ziziphora tenuior L. essential oil. The components of the nanocapsule of Aloe vera gel was water, toewin and Ziziphora tenuior L. essential oil. Fresh Aloe vera leaves were used to prepare gel. Zeta-average diameter, particle size distribution, scattering index (PDI) and zeta potential (particle surface charge) were measured. Transmission electron microscopy (TEM) imaging was used to evaluate the morphology of the nanocapsule. The stability of produced nanocapsule was evaluated by measuring the particle size changes for 3 months.
21 compounds were identified in the essential oil of Ziziphora tenuior. The main and important constituents of Ziziphora tenuior L. essential oil were Pulegone, Menthofuran and 1,8-Cineole. The results showed that the particle size of nanocapsule containing essential oil was 84.46 nm and zeta potential was -16.02 mV. The results of transmission electron microscope (TEM) photos showed that the size of the particles is less than 200 nanometers and the shape of the particles is almost spherical. The outer surface of the capsules is completely smooth and uniform. Stability studies of particle size and zeta potential for 3 months showed that nanocapsule containing essential oils had good stability. In this formulation, the zeta potential was about -16 mV, which is due to the non-ionic parts of the surfactant on the surface of the nanocapsule, which contributes to the repulsion force and caused the stability of the size of the nanocapsules. In order to determine the amount of essential oil in the nanocapsule, spectrophotometric method was used. The percentage of essential oil in nanocapsule was 83.25%.
Nanoencapsulation of essential is one of the ways to reduce the limitations of essential oil aplication. In the present study, a nancapsule with natural and biodegradable materials (Aloe vera gel) containing Ziziphora tenuior L. essential oil was prepared and the results showed that Ziziphora tenuior L. essential oil was successfully encapsulated in Aloe vera gel. In general, the results of the present study showed that the nanocapsule of Aloe vera gel is a suitable carrier for Ziziphora tenuior L. essential oil and can be used as an oral coating to preserve fruits and vegetables.

Barberries are a broad class of spiny evergreen or deciduous shrubs belonging to the Berberidaceae family. They are of great importance due to their different parts' nutritional and medicinal properties and their ornamental applications. Genus Berberis, the biggest genus in Berberidaceae, includes more than 660 species. Barberry grows in Asia and Europe and has been used extensively as a medicinal plant in traditional medicine. In Iranian traditional medicine, several properties, such as antibacterial, antipyretic, antipruritic and antiarrhythmic, have been reported with unknown mechanisms of action. Incredible structural diversity among barberries' active components makes them a valuable source of novel therapeutic compounds. Seedless barberry (Berberis integerrima 'Asperma') is one of Iran's valuable indigenous medicinal plants. Common asexual propagation of this plant over the years and consequently low genetic diversity in populations of the seedless barberry restricts selection outcomes in breeding programs. Utilizing the indigenous wild genotypes of the barberry genus, which are easily able to cross-pollinate, is one of the best methods to increase genetic diversity. Accordingly, several wild seedy barberry genotypes were identified from all over Iran, collected and established in a collection in Mashhad; then, 16 genotypes were selected and their physical properties were studied. 
In this study, ripe fruits of sixteen unique genotypes (i.e., Iranian seedless barberry and fifteen seedy genotypes) were harvested in October- November 2015 and kept in a refrigerator in order to measure some of their physical properties in fresh fruits (berry dimension, 100-berry weight, juice content and color indices). For other properties, fruits were dried at room temperature. Fruit cluster length was measured by means of a ruler, the number of berries/cluster and the number of set/aborted seeds in berry by counting, berry dimensions by a digital caliper, weight of fresh and dried 100-berry, percentage of pulp and seed as well as fruit juice content by a scale with 0.001 accuracy. Moisture content was determined using an oven with 75 ºC temperature for 48 hours. Color indices, including L*, a* and b*, were measured using a portable colorimeter (Konica Minolta Chroma Meters CR-410). This study was performed using a completely randomized design with three replications. Data were analyzed by Minitab software version 16 using analysis of variance (ANOVA), and differences among means were determined for significance at p<0.05 using the Bonferroni test.
The results indicated significant differences among genotypes. Based on the results, cluster length ranged between 1.67cm (code 5-3) and 6.29 cm (code 10-1); moisture content was between 8.20% and 11.84% in genotypes 8-3 and 13-2, respectively. The fruit juice content range of the studied genotypes was between 51.22% and 71.87%. Genotype 2-1 had the highest dimension values and the highest 100-berry fresh weight (30.72g) and dry weight (10.00g) fruits. The lowest weights of 100-berry were related to 14-1 and seedless barberry. Genotypes 5-2 had the highest pulp percentage (98.17%) and the lowest seed percentage (1.50%) and 10-1 had the lowest pulp percentage (51.93%) and the highest seed percentage (48.07%). The highest number of set seeds (1.73) and the lowest number of aborted seeds (zero) were found in (10-1) and (14-2), respectively. Based on the results, seedless barberry had the lowest number of set seeds (0.00) and the highest number of aborted seeds (3.27). Regarding fruit color indices, genotypes showed significant variability from orange to brown and dark blue. Color indices L*, a* and b* ranged (from 22.83 to 38.13), (2.31 to 37.76) and (1.18 to 2.28), respectively.   
In conclusion, it can be said that all genotypes have considerable variability in fruit traits (color, fruit dimensions, pulp/seed percentage, moisture content, etc.). Based on the result of this study, genotype 5-2 was the most similar genotype to seedless barberry. The seedless barberry populations have low genetic diversity due to asexual propagation through suckers over many years. Indigenous genotypes can be a valuable genetic resource for future breeding programs to improve the quantitative and qualitative characteristics of seedless barberry and introduce new cultivars of seedless barberry with different colors and consequently different nutritional- medicinal properties.

The present study was aimed to evaluate the effect of organic fertilizers of folic acid and amino acids (glycine and glutamic acid) on the plant resistance to stress and yield of cucumber under deficit irrigation conditions. The study was carried out as a factorial in randomized complete blocks with 3 replications. The first factor was fertilization at four levels as control, 200 mg/l folic acid, amino acid glycine and glutamic acid (6 liters per ha), and folic acid + amino acids (glycine and glutamic acid). The second factor was irrigation interval (3, 5 and 7 days). The results showed that an increase in irrigation interval caused a significant reduction in plant dry and fresh weights, internode length, root and shoot lengths, stomatal conductance and chlorophyll contents. Furthermore, combined use of folic acid and amino acid and 7 day irrigation interval increased root length, internode length, leaf area, chlorophyll a and relative leaf water content by 159, 46.9, 84.7, 138 and 36%, respectively, when compared with the control at the same irrigation interval. In addition, a 70% increase in plant fresh weight and 84% increase in fruit weight were observed in irrigation interval of five days and combined treatment of amino acid and folic acid. In general, it can be concluded that the combined application of amino acids and folic acid improved the morphophysiological characteristics of cucumber under deficit irrigation conditions, while it was not effective in improving yield and fruit production with the seven-day irrigation interval.

The deficiency of organic matter in the soil is one of the factors limiting cultivating and growing of plants. While the organic matter is the main factor of soil fertility and the ideal organic matter content of agricultural soils is about 4-6% according to the experiments performed, this amount is very low in arid and desert areas such as those  in Iran. The significant capability of humic fertilizers in the rapid improvement of soil fertilization level is quite recognizable. Humic acid has a direct role in determining the producing potential of the soil. Humic substances can have a positive effect on plant growth in different ways. Humic acid results in an increasing nitrogen uptake by plants and stimulates and enhances the uptake of Ca, Mg, P, and K. By enhancing the resistance to environmental stresses, increasing chlorophyll concentration and thus affecting photosynthesis, amino acids are effective in plant growth and yield. Given the conditions that agriculture faces, drought is the main limiting factor of agricultural production in the present and future. Research has reported that the improvement of plant growth under stress conditions by application of humic substances and amino acid. The use of these factors that increase plant growth in stressful conditions and improve yield is a useful and effective method. The aim of this study was to investigate the effect of organic fertilizers on growth traits of cucumber plants under drought stress.

In order to explore the effect of drought stress on cucumber plant, an experiment was carried out in the research field of agriculture faculty of Ferdowsi University of Mashhad in 2015-2016. This study was performed as a factorial design in a completely randomized block design with three replications. The first factor was fertilization at four levels (control, humic acid application (200 ppm), glycine amino acid and glutamic acid application (6 liters per hectare), and combined application of humic acid (200 ppm), glycine amino acid and glutamic acid (6 liters per hectare), and the second factor was irrigation at three levels of 3, 5 and 7 days. Furrows with 2 m apart, 40 cm deep, 50 cm wide and 20 m long were created. Following the soil irrigation, the cucumber seeds were planted on the edge of the experimental hills (4-5 seeds per hill) that were spaced 50 cm apart. The treatments were applied via irrigation at specified concentration. At the end of the experiment Morphophysiological traits were measured.

The results showed that drought stress reduced fresh and dry weights of plant, a number of branches, root length, stem length, and internode length. The amount of available water to plants affects their growth traits. Increasing irrigation interval decreased vegetative growth parameters in this plant, which is undoubtedly due to the lack of water available to the plant. Drought stress leads to stomata closure, plant wilt, swelling reduction, and reduced water content and total potential of the leaf, resulting in decreased cell division, especially in shoots and leaves. As a result, the first effects of dehydration in plants can be seen in their smaller leaf size and lower height than normal conditions. The highest level of drought stress (7 days) decreases all the traits. Unfortunately, the use of humic acid and acid amine had no effect on the highest levels of stress (7 days). The application of humic acid alone could improve the effects of drought stress on the plant. Humic acid enhances plant growth by affecting plant cell metabolism as well as chelating power, increasing nutrient uptake, and increasing nitrogen content. Experimental studies have shown that glycine betaine strengthens enzymatic structures and activities and protein components, and cell wall stability against the damaging effects of environmental stresses is considered to be one of its activities. It seems that organic matter and humic compounds including humic acid through positive physiological effects including effects on plant cells metabolism, increased leaf chlorophyll concentration, increased metabolism within cells, and increased durability of photosynthetic tissues (Increasing leaf durability) leads to increase of production performance and biomass production in plants.

The use of humic acid alone led to improved leaf area, root length, and other traits. These factors caused an improvement in the photosynthetic rate in the plant, resulting in improved yield and growth under drought stress conditions (increased irrigation intervals). The protective and moderating role of the humic acid application under drought stress is one of the reasons for growth improvement by these compounds. In general, the combined application of humic acid and amino acid in the form of irrigation fertilizer in cucumber under drought stress improved growth traits and prevented yield reduction.

Spinacia olerace is the most important leaf vegetable of the Chenopodiacea family, which has a special place in human nutrition because of its variety of minerals and vitamins. Cultivation of this plant in Iran is several thousand years old and accordingly Iran is considered as the main place and a source of spinach in the world. Growth of plants is affected by genetics, environmental conditions, growing season, nutrients, and soil, harvesting method, temperature, intensity and quality of light. Among these factors, soil nutrients have a significant influence on plant growth and yield. Nowadays, the consumption of organic matter as fertilizer due to its high cost and limited availability is not sufficient and the major nutritional needs of plants are met by chemical fertilizers, which can lead to environmental problems and, over time, reduced yields. In this connection humic acid is a naturally occurring organic compound and contains 2% to 5% organic matter. Humic acid can be used to seedling nutrition and improve its quality and quantity. Given the recent use of organic acids such as humic acid to improve crops and horticulture, but little research has been done on transplant birth, this experiment was conducted to investigate the application of different levels of humic acid in irrigation water at the time of irrigation. Different effects and their effects on growth indices and spinach production were investigated.
The present experiment was conducted to investigate the application of different concentrations of humic acid at different times and its effects on quantitative and qualitative indices of spinach in a factorial completely randomized design with three replications in research greenhouse at Torbat Heydariyeh University. Treatments consisted of three concentrations of humic acid (0, 3 and 6 ml/L) at two application times (one-week and two-week). The mean daily greenhouse temperature at the time of plant growth was 25°C and the mean nighttime temperature was 18°C, the average relative humidity was 60%. After seedlings were planted in the main pots at four-leaf stage, they were irrigated with humic acid (0, 3 and 6 ml/L) at different intervals once a week, twice weekly. The humic fertilizer used belonged to Green Seed Company, containing 24% humic acid and 3% folic acid and 2% potassium. Five weeks after treatment, the traits were measured. Transplant growth indices including number of leaves (by counting the number of shoots per plant), leaf length and width, leaf area, canopy, height, chlorophyll index, chlorophyll a, b, carotenoid and dry weight of each plant were determined.
Based on the results of this experiment, the effect of humic acid concentration on morphological and physiological traits of spinach transplant was significant. The highest leaf number (4.6) at 3 ml concentration and the lowest number (3.5) were at zero concentration. These traits were subjected to humic acid titer, but the increase in concentration had no significant effect on these traits. The increased number of leaves and traits mentioned in the early stages of transplant growth is probably due to the rapid expansion of the root system of the plant at high concentrations of humic acid, which in turn leads to increased nutrient uptake, better plant growth and subsequent growth. Leaf number and other traits become leaf dependent. The results showed that the highest chlorophyll a (1.8 ml/g fresh leaf), chlorophyll b (2.5 ml/ml fresh leaf), carotenoids (7.1 ml/ml). Fresh leaf g) and biomass (150 mg) at 3 ml concentration and the lowest at zero concentration. The highest chlorophyll index (74.1 ml/ml fresh leaf g) was also found in the concentration of 6 ml and the lowest was obtained from zero concentration. Humic acid increased spinach transplant biomass by increasing the amount of photosynthetic pigments and leaf area or the same photosynthetic capacity. In most of the traits, the two-week application time was higher than the one-week, so that spinach transplant biomass increased by 110% over the two-week application period. So that spinach transplant biomass was 156 at the two-week application and 74 mg at the one-week application. Based on the results of this experiment, humic acid application can improve the quantitative and qualitative traits of spinach transplant and its production.
Production of vegetable seedlings have an important role in the production and olericulture economy. Specializing in different activities in the vegetable production process will simplify the production process and increase efficiency. This means that the best conditions for seedling growth should be provided during transplanting. Application of humic acid organic fertilizer instead of chemical fertilizer can reduce environmental pollution in line with sustainable agriculture and healthy eating with vegetables to prevent the accumulation of chemicals in the human body to be effective. In this regard, the results of this study showed that using low humic acid as organic fertilizer can improve morphophysiological traits of spinach transplant.

Choosing the best covering material for the greenhouse roof is a very important factor influencing the quantity and quality of light entering the greenhouse. Some vegetative and reproductive traits and biochemical characteristics of two tomato cultivars (‘Synda’ and ‘Melody’) grown in some greenhouse units roof-covered with four covering materials (glass, plastic, polycarbonate and corrugated polyethylene) were investigated for autumn cultivation in the Research Greenhouses of Ferdowsi University of Mashhad. This experiment was designed in a split plot (main-plot: greenhouse cover; sub-plot: cultivar) based on a completely randomized design. The highest to lowest radiation rates were recorded in corrugated polyethylene, glass, plastic and polycarbonate covers, respectively. The ANOVA results showed that vegetative, reproductive and biochemical traits were significantly affected by greenhouse cover, cultivar, or greenhouse cover × cultivar interaction. Raising the plant health index through increasing the stem diameter and decreasing plant length was influenced by the amount of the irradiation provided by greenhouse covers; it was significantly higher in the corrugated polyethylene and glass covers rather than the plastic and polycarbonate ones. The maximum numbers of days from transplanting to flowering stage were obtained in the corrugated and glass covers (35.5 and 35 days, respectively) for the ‘Synda’ cultivar, and in glass cover (32.2 days) for the ‘Melody’ cultivar. The lowest fruit ripening (60 days) was observed in the ‘Melody’ cultivar under the corrugated polyethylene cover, while the highest value (80.25 days) was recorded in ‘Synda’ cultivar under the polycarbonate cover. Fruit production was the highest in the ‘Synda’ cultivar under corrugated polyethylene (6503.6 g/plant) and glass (6337.3 g/plant) covers, while ‘Melody’ under plastic and polycarbonate covers (1314.2 and 1027.1 g/plant, respectively) showed the lowest amount. According to the results of this experiment, from an economic point of view, based on Net Present Value (NPV) and Internal Rate of Return (IIR) factors, the greenhouse cultivation of ‘Synda’ cultivar under glass cover is recommended in Mashhad climatic conditions.

Greater celandine (Chelidonium sp) is one of the plants that its propagation through seed occurs slowly. In addition, Chelidonium majus L. has limited habitats in Iran. For this reason, micropropagation can be considered as an effective method for its rapid and massive propagation and conservation, which can lead to the production of highly uniform plants. Chelidonium majus L. also contains a large amount of secondary metabolites of Isoquinoline alkaloids, including Chelidonine, Sanguinarine, Captesin, Berberrine and Chloritrine, and phenolic compounds. Therefore, the aim of this study was to investigate micropropagation of Chelidonium majus L. and compare the total phenol content in leaf, stem and root in obtained plantlets.

To begin the experiment, seeds of Chelidonium majus L. were first washed with distilled water containing a few drops of tween20. Then they were washed with 70% alcohol for 1 min and were finally washed with double-distilled water. Next, they were disinfected with 1% sodium hypochlorite for 5 min, and again were rinsed with distilled water for 3 times of 5, 15, and 180 min under laminar air flow hood. The effects of TDZ at concentrations 0, 0.25, 0.5, 0.75 and 1 mg/L, BAP at concentrations 0, 0.5, 1, 1.5, 2 mg/L considered. Then, the effect of best treatment in combination with NAA and IBA at 0.25, 0.5, 0.75 and 1 mg/L on growth parameters (number of shoot, shoot length and shoot formation capacity index), were studied. The effect of IBA, NAA and IAA at 0, 0.5, 1, 1.5 and 2 mg/L on rooting parameters (number of root and root length) in MS medium supplemented with 3 g/L activated charcoal in in vitro conditions were evaluated. Then different ratios of cocopeat, perlite and peat moss were used for acclimatization of the obtaining plants. Folin method was used to measure total phenol content. The experiment was conducted as factorial in a completely randomized design with four replications.

The results of analysis of variance for proliferation and rooting traits showed that there were significant differences among the treatments at 1% probability level. The results of means comparison showed that the highest numbers of shoots and shoot formation capacity index were obtained  from the treatment of 0.5 mg/L TDZ with the average of 8.12, which did not show a significant difference from the concentration of 0.25 mg/L TDZ, and the lowest shoot number was related to the control treatment. Increasing the amount of TDZ hormone led to the reduction in shoot number, so that at concentration of 1 mg/L TDZ, the average shoot number per explant was four. Combination of 0.5 mg/L TDZ with IBA and NAA had lower effect on Chelidonium majus L. proliferation. Moreover, the greatest shoot length was observed in the treatment of 2 mg/L BAP. Comparison of means values showed no significant difference between the treatments of 2 and 1.5 mg/L BAP at 1% probability level. In this study, MS medium containing 1.5 mg/L IBA was the most appropriate treatment for root formation. The effect of NAA hormone on root number of Chelidonium majus L. showed that the highest number of root was obtained from the treatment of 2 mg/L NAA. Besides, the effect of IAA on root number of Chelidonium majus L. showed that the highest number of root was observed in the treatment of 1 mg/L IAA, and the lowest number of root was related to the control treatment .The results of means comparison for the percentage of acclimatized plants showed that the ratio of 0:2:1 had a significant difference from the rest of the culture media and 85% of the plants were acclimatized, while the ratio of 1:2:1 showed the lowest percentage of acclimatization (20%). Furthermore, the results showed that the culture media had significant effect on acclimatization stage at 1% probability level. The results of the analysis of variance for total phenol content in leaf, stem and root tissues showed that there were significant differences among these three tissues. The results showed that the amount of total phenol in leaf was higher than in the stem, and the amount of phenol in root was insignificant.

Based on the results of this study, micropropagation can be used as a method for commercial production of this species under in vitro conditions.
