Abstract
This, study was carried out in the Abu Rawash province area Giza Governorate during two successive seasons 2014, 2015.Four grain cultivars were selected (Wheat Masr1, Wheat Masr2, Barley Giza 2000 and Barley Giza 130). This study aims to achieve the effective use of some bioagent induces to increase the resistance of wheat and barley against some diseases that afflict the ears of grain . by using safe and natural compound to control some of the diseases of both wheat and barley and know the impact of them on agricultural products whereas biotechnology and natural compounds were safe of both quality and technological for both, wheat and barley. The maximum fresh weight/1000 grain were obtained with Streptomyces, ther followed by Trichoderma harziunum and the latest one was Trichoderma viride in both seasons. While, the lowest increase of 1000grain weight were recorded in case of control. Streptomyces and Trichoderma viride recorded the highest reduction of damping off powdery mildew and Leaf Rust of survival wheat plants. CV Barley Giza 2000 gave fresh weight/ 1000 grain weight, powdery mildew and Leaf Rust in both seasons as compared with CV Barley Giza 130. Inoculation of barley (Giza 2000 and Giza 130) with Streptomyces increased total protein and fresh weight/ 1000 grain in both seasons. As for the rheological quality, the best treatments with Trichoderma viride were found to have a non-significant difference between Masr1 and Masr2 wheat cultivars in water absorption, arrival time and dough growth time with treatments (Streptomyces lydicus. methyljasmonate, Trichoderma harziunum, control(.
