Chemical and biochemical activities of bean (phaseoulus vulgaris) cultivars were studied in three red bean cultivars (V1, V2, and V3) at the two levels of irrigation and two different amounts of super absorbent (0 &7%). Field experiment was conducted in 2005 and the experimental design was randomized by complete block in a split plot arrangement with three replications. Our results showed that, the drought stress significantly increased the activities of some antioxidant enzymes (catalase, glutathione redoctase and super oxid dismutase) content. Of course, the content of antioxidant enzymes was more at moderate than extreme water deficit. Lipid and protein oxidation (malondialdehyde and dityrosine contents) also significantly increased in response to water deficitinduced. As it was shown, stress decreases the yield and it can increase biochemical characters and on the other hand, using 7% super absorbent in field situation increases its agricultural characters.
