mycorrhiza (glomus mossea) effects on protein percent and agronomic traits of four varieties of corn in the sistan region

for study the effect of arbuscularmycorrhiza fungi a factorial experiment in a randomized complete block design with four replications was carried out in the summer of 1389 at the agricultural research station in city of zahak. the experiment included two factors; the first factor was inoculated glomus mossea mycorrhiza and no-inoculated one. the second factor was in four varieties of corn: s.c. (770), tisa, s.c. (7020) and s.c. (704). results showed that application of arbuscular mycorrhiza fungi on plant height, flag leaf width, number of grains per ear and plant protein had a very significant effect; and flag leaf length had a significant effect. arbuscular mycorrhiza fungi on the stem diameter, leaf number and 100 seed weight had no significant effect. interactions of arbuscular mycorrhiza fungi and digits only 100 seed weight had a very significant effect; and plant height and percent protein had a significant effect. but the stem diameter, leaf number, flag leaf length, flag leaf width, number of grains per plant had no significant effect.
