Abstract:Using partially sterile culture method,effects of different nitrogen nutrition on the growth and antioxidant characteristics of rice (Oryza sativa L.) stressed by drought was studied.Drought stricken on the plant was induced by polyethylene glycol(PEG).The results showed that,higher foliar dehydration resisting capacity and higher shoot dry weight cumulation was observed for the rice treated with organic nitrogen compared with rice supplied with no nitrogen or inorganic nitrogen.A higher foliar water potential was also found for the organic nitrogen treated rice.Under drought stress,rice supplied with organic nitrogen could maintain comparatively higher activities of SOD,POD and CAT in the leaves and lower membrane peroxidation(Expressed by MDA content).
