EFFECT OF SYMBIOSIS INTERACTION OF MYCORRHIZAE ARBUSCULAR ON MINERAL UPTAKE IN WHEAT ( PISHTAZ CULTIVAR)

Background and Aim:Mycorrhizal fungi form a close symbiotic relationship with plant roots and help the roots to draw nutrients from the soil .Methods:In order to study the effect of symbiosis interaction of Mycorrhizae Arbuscular on mineral uptake in wheat ( Pishtaz cultivar), a greenhouse test with 11 treatments (2 species of Glomus mossea, 2 species of G. intraradices, 2 species of G. clarum, 1 species of G. etanicatum, 1 species of G. caledonium, 1 species of G. claroideum, 1 control treatment without mycorrhiza inoculation, a mix treatment with different species was done in greenhouse of biology department of Soil and Water Research Institute in completely randomized design.Results:Result showed that root colonization percentage was significantly (1% probability) increased in harvest time of wheat and reached to 50% of root system. Maximum shoot dry weight was in T7 (G. claroideum) and it was 11.89 g per pot. Wheat root symbiosis with fungi, increased uptake of P, K, Zn and shoot dry weight (5% probability). Maximum P uptake was in T4 (G. intraradices) and it was 29.9 mg per pot. Maximum K uptakes were in T7 (G. claroideum) and T11 (mix treatment with different species), they were 175.95 and 173.41 mg per pot respectfully. Maximum Zn uptake was in T11 and it was 0.947 mg per pot.Conclusion:T11 had better results in most of measured parameters comparing to other treatments.
