Abstract: 

Super absorbents could be able to absorb and keep it the water several times of their volume. The following research has been carried out with purpose of investigating the effects of different levels of water deficiency stress and super absorbent on yield, antioxidant enzymes activity and cell membrane stability in mustard in field experiments in research station of Islamic Azad University, Karaj branch. The plan which was taken advantage of in this research was factorial randomize complete block design with totally random blocks repeated three times. The treatments included five levels of water deficiency stress (Irrigation after 80 mm evaporation from class A evaporation container, cut irrigation from booting stage, flowering stage, silicling stage and grain filling stage) and three levels of applying super absorbent (amount of 0, 5 and 7 Weight percentage). The traits underwent the experiment were: the performance of the seed, biological performance, harvest indicator, the weight of one hundred seed, the activity of the antioxidant enzymes (catalase and super oxide dismutase) and cell membrane stability. The conclusions showed that effects of water deficiency stress and super absorbent was significant. The mutual impact of water deficiency stress and super absorbent weren’t significant for any treats. Normal irrigation and usage of concentration of 7 %, level 3, of super absorbent with mean of 5.803 and 25.78 ton/hect showed the most seed and biological performance. Cut irrigation from booting stage without applying super absorbent with mean of 206.1 and 5231 u/mg.protein showed the most activity of catalase and super oxide dismutase and with mean of 2683 Ls/cm showed the least cell membrane stability.
