Abstract:

The fungi of vesicular-arbuscular mycorrhiza (VAM) as a benefit microorganism are used in various purposes, such as mining, agriculture and environmental science. In agriculture, utilization of VAM as benefit manner and biological efficiency for plant growth and nutrition is an important symbiotic with crops. The effects of different mycorrhizal fungi symbiosis with sorghum genotypes were studied in growing season 2006-2007 in Agriculture and Research Institute of Dryland Area, Zabol, Iran. This experiment was based on factorial completely randomize design with two factors in four replications in field condition. The first factor was in three levels including KGS 25, KGS 29 and native. The second factor was mycorrhiza in three levels including without mycorrhiza and various species of Glomus etanicatum and G. mossae. The results showed that there are significant differences between cultivars of sorghum and using mycorrhiza on plant height, number of seed in spike, biomass, root colonization. Also the results indicated that in order augmentation of plant growth and crop yield it is necessary to choose the most effective fungus species. G. mosseae species were best mycorrhiza strains among studied species. VAM colonization improved most characteristics of sorghum in semiarid lands.
