The value of symbiosis mycorrihizal fungi for different plant species; Case study: Celtis caucasica L

Among important symbioses, mycorrhizal symbiosis helps the establishment of plant by increasing the rhizosphere distribution, and absorption of water and important soil nutrients such as N, P, and K, leading to increased biodiversity, soil microbial population, and plant resistance against some pathogens and different stresses. This research was aimed to study the influence of symbiosis on morphological characteristics of Celtis caucasica. The study was performed in a natural habitat at Chahartagh, Chaharmahal va Bakhtiari province. The rhizosphere soil and root of five individuals of C. caucasica were sampled. After assessing the symbiosis, arbuscular mycorrihizal fungi were amplified by Zea mayz. Afterwards, the seeds of C. caucasica were inoculated by fungi. Assessments showed that symbiosis was created with 80% colonization. Therfore, the stem height, leaf area and root length in mycorrihizal seedlings were more than 3, 3, and 1.5 times as compared with control seedlings. Therefore, the symbiosis of arbuscular mycorrhizal fungi caused the better growth of mycorrhizal seedlings.
