In this reserach, nectar and pollen producing plant species of Kohgiluyeh and Boyer-Ahmad provinces have been studied. The results of this study showing that 282 plant species belonging to 162 genera from 55 genera used by honeybees in the province. Asteraceae with 49 species (17.80%), Fabaceae with 34 species (15.2%), Lamiaceae with 33 species (11.74%), Brassicaceae with 23 species (8.15%) including the highest number of mentioned plant taxa in the province. Also, 169 (60%) of these plants produce nectar and pollen, 41 species (15%) produce nectar and 72 species (25%) produce pollen only. In addition, seven species vulnerable (VU) and one species endangered (EN). In addition, 36 species are endemic to Iran. The konar, Gavan pang angosht, Qangal and Zol are among the most important mono floral honeys in the province so the conservation and management of their habitat is one of the conservation priorities of rangelands in this province.

The presence of heavy metals in water, air, soil and human food chain has indeed been a significant challenge in recent years that may put human life in jeopardy. Honey is one of the products which may be polluted by these metals. The aim of this study was to determine the levels of mercury and lead, supplied in Eastern Azarbaijan and Ardabil provinces. 50 samples of honey were collected randomly from the markets of the two provinces during May, 2015. The levels of mercury and lead were determined using atomic absorption spectrometry. The levels of the determined heavy metals were below the international standard (which is 1ppm for lead and 0.05 ppm for mercury) in all the tested samples. Unlike the levels of lead which were higher in the samples of Eastern Azarbaijan, mercury had a greater amount in the samples of Ardabil. The differences in the amounts of heavy metals in the two provinces were not significant though (P>0.05). The presence of these heavy metals in honey may be due to highly dense population in the areas, urbanization, industrial companies and traffic jams caused by countless transportation vehicles. Due to the fact that Iran has a considerable potential in producing and exporting honey, the safety of this product is of paramount importance and necessary measures must be taken to ensure its safety.

In this research, pollen morphology of 10 species of 8 attractive plants for bees were studied using SEM microscopy from different parts of Kermanshah province. The methods used in this study included: 1- Field visit and pollen collection directly from the flowers; 2- Using the trapping device installed in front of the hive lid; 3- Removing the pollen from the inside of the hive. Several reference books and relevant websites were used for pollen identification. Results showed that the majority of pollen grains had medium size but there were few large and very large pollen grains. Their shape was prolate - spheroidal, prolate and the outline of pollen grain is as the oblate-spheroidal form in polar view and as an elliptical from in equatorial view. The position of aperture in studied pollens were monosulcate, tricolpate, tricolporate, monoporate and pantoporate. The exine ornamentation were reticulate, striate, granulate, psilate, echinate. Also, the highest pollen collected by the bee was, respectively, Asteraceae, Rosaceae, papilionaceae and Apiaceae.

Besides nutritional value, honey has been widely appreciated in medicinal use since ancient times. The antibacterial properties of honey on a wide variety of microorganisms, particularly bacteria causing wound infections, has been demonstrated. Due to the resistance of many bacteria to antibiotics, this feature of honey is particularly important. Honey composition is diverse according to plant origin, geographical area and also processing methods. Proteins and enzymes are the most important components of honey, which are crucial in determining its quality. Floral origin is one of the most important parameters of honey quality and is economically important. For attribution of floral and geographical origin in the composition and therapeutic properties of honey, the necessity of assessing and evaluating new honey types from different floral species and various environmental conditions will be approved. Considering the advantage of the climate diversity and vegetation of Iran, improving the quantity and quality of production, processing and supply of honey in the country, not only impact on the public health promotion and increase participation in agricultural products, can improve the country’s pivotal role in providing the regional standards is honey.
