| Effects of triacontanol(TRIA) on several parameters of senescence including the changes of related enzyme activities were investigated in radish(Raphanus sativus L._ cotyledons developing in light. In senescing radish cotyledons, 1.0mg TRIA/1 retarded the degradation of chlorophyll content. Moreover, it depressed the increases of malondialdehyde and H2O2 contents compared to the control. Catalase and superoxide dismutase activities were highly maintained but the increase of peroxidase activity was inhibited remarkably under the TRIA application. These results suggested that TRIA participated in the regulation of senescence during the late part of cotyledon development where it delayed senescence through its action on free radical-associated enzymes and consequent metabolic turnover. |
