Abstract:

Florescence and flower Senescence are complicated physiological and biochemical processes. Navel orange was taken as experiment material to investigate the changes of anti-oxidant activities during florescence and flower senescence. The results showed that MDA content accumulated and the activities of SOD, CAT, GPX first increased then decreased, but APX decreased during florescence and flower senescence. Therefore, one of important reasons for florescence and senescence of navel orange is the disorder of metabolism induced by the accumulation of active oxygen species.
