Distribution of Arbuscular Mycorrhizal Spores in Areas in the Çumra Plain Where Wheat is Cultivated

Biodiversity and distributions of mycorrhizal spores exhibit variation in different ecosystems and depending on the kind and presence of plant communities in these ecosystems. When there is a good interaction between a plant and mycor-rhizal spores, resistance against all unfavorable weather conditions, above all drought, is better in infected plants than in uninfected plants in all circumstances, especially drought. In this study, which we conducted in the Çumra Plain, where wheat is cultivated in large amounts, distribution of arbuscular mycorrhizal fun-gus (AMF) spores in Çumra, Alibey and Alemdar soil series was determined. Although presence of mycorrhizal spores varies depending on different proper-ties of soil, it was found that the number of spores determined in the 3 series on which the study was conducted was above the optimum level that was supposed to exist in soil. The difference between the distributions of spores in the series was not found to be significant (P 0.01 and P 0.05). However, the order of the series was identified as Alemdar series Alibey series Çumra series (132.81 113.97 109.731 number/10 g dry soil) in terms of average spore num-bers.
