فعالية التلقيح المزدوج بفطريات المايكورايزا الشجيرية Glomus mosseae و البكتريا المثبته للنتروجين Azotobacter chroococcum في نمو و إنتاجية بعض التراكيب الوراثية لمحصول الشعير Hordium vulgare L.

الملخص EN

This investigation was conducted to determine the response of 12 genetic recombination of barley crop to bioinoculation with mixture of Glomus mosseae (Nicolson & Trappe.

) Gerd &Trappe 250 spores/gram soil and 10 ml(10 cfu/ml) of Azotobacter chroococcum /0.5meter seeded line.Treatments were distributed in randomly block design with three replicates on 2010-2011 growing season .

Growth parameters : Percentage of germination, Flowering after 106 days of germination , Maturity after 130 days of cultivation, Number of branches after 126 days of cultivation, Dry weight of vegetative growth, The number of spikes in the line, Number of grains per spike, Average weight of 1000 grain, and The total weight of seeds in the line were taken.Results reveald different response of the tested recombinations for biofertilizers effects.The recombinations Al Iraq ,Klebar ,Rafidane ,Alkair ,Arevat ,Albaraka ,Tuwatha ,Furat 9 , Sameer ,Showuaa, reveald significant increasing differences (0.05 level) in most growth and productivity parameters specialy Showuaa, Rafidane, Alkair which recorded increament at 32% ,25% ,23% respectively ,while the recombinations MH-421 ,M7020 showed no response and recorded reduction percentages 5% ,50% as comparison with control respectively.
