چکیده:

Antioxidant enzymes activity increases in plant cells as a response to environmental stresses. Environmental stresses can result in the production of Reactive Oxygen Species (ROS), including O2+ , H2O2 and OH? ; these ROS adversely affect crops yield and quality. To investigate the effect of vermicompost and N fertilizer application on antioxidant enzymes activity under water deficit stress of Safflower in 2014 at Khorramabad- Lorestan , Iran. The experiment was arranged in Factorial Randomized Complete Block Design as split plot- factorial with 3 replications. Treatments were included three agents: Vermicompost rate in 4 levels (V1=0 (control), V2=2, V3=4 and V4=6 ton Vermicompost ton/h-a-1) and Nitrogen rate in 4 levels (N1= 0 (control), N2= 50, N3= 100, N4= 150 kg N ha -1) in the form of Urea and Irrigation as the main factor in two levels, S1=regular irrigation and S2=Non- irrigation (stress from bloom growth stages). The results revealed that water stress increased antioxidant enzymes activities and whit application Vermicompost and Nitrogen the antioxidant enzymes activity decreased then the control treatments
