Effect of foliar application of selenium onquality traits and enzyme activities of safflower (Carthamus tinctorius. L) under different soil moisture regimes stress in varamin region

In order to study the effect of selenium foliar application on yield and yield components of safflower (Carthamus tinctorius.L) under different soil moisture regimes stress an experiment in split plot based on Randomized complete block design with three replications in 1393 in The Islamic University research farm Varamin unit. Treatments were main plot drought in four irrigation regimes including 50 (Control), 80, and 110 mm evaporation from evaporation pan (Class A) and sub plotconsisted offour levelsof selenium (Control, 100, 200 and 300 mg/lit) respectively. Results showed a significant effect of drought stress and selenium on Catalase, Glutathione, Superoxide dismutase, Oil and protein percentage. Effect of selenium on selenium content of grain was significant but the effect of drought stress on this trait is not significant. Interactions between drought stress and selenium on selenium content of grain and oil percentage was significant and The Best Results in normal irrigation (control) and 300 mg treatment was obtained.
