The Effect of the Arbuscular Mycorrhizal (AM) Fungus Glomus mosseae on the Growth and Yield of of three ecotype of hemp (cannabis sativa L.) under saline soil and saline water

In order to evaluate the effect of Arbuscular Mycorrhizal (AM) fungi species (Glomus mosseae) to salinity stress of three ecotype of hemp، a study was carried out at a fields in north east of Isfahan city in 2012 growing season. The experimental design set as factorial based on randomized complete block design with three hemp ecotype (Shiraz، Mashhad and Isfahan) and Arbuscular Mycorrhizal fungi species of Glomus mosseae and control under saline soil and saline water. Result showed that the total dry weight، height، number of latral shoots and grain yield of Mycorrhizal plant was highest than the non Mycorrhizal plant. The ecotype of Shiraz with Mycorrhizal had the highest precente of K+. AM fungi significantly enhanced the concentration of K+. Hemp Mycorrhizal plants absorbed less amounts of Na+ and inhibit their transfer to the shoots. In this reaserch obsrvered ecotype of Shiraz with Mycorrhizal had the most resistance to salinity under salin soil and water.
