| Abstract: | Relationchip between detached leaves senescence of hybrid rice cv. Shanyou 63 and protein metabolism was studied. During the senescence of detached leaves, the contents of chlorophyll and soluble protein decreased, and the contcnt of free amino acid increased, and the activities of aminopeptidase and endopeptidase markedly rase. The results suggested that the main reason why protems were degraded was the proteolysis of aminopeptidase and endopeptidase in senescent leaves. |
