Abstract
The effects of abscisic acid (ABA) and water stress on senescence and enzym e activities of oxygen scavenging enzymes of detached rice leaves were comp ared. Exogenously applied ABA exhibited water stress-like effects by promot ing senescence, by decreasing the activities of catalase, peroxidase, ascor bate peroxidase and superoxide dismutase. It seems that the effects of wate r stress on senescence and enzyme activities are possibly mediated through increased content of endogenous ABA.
