Study on Physiology Characters of Senescence in Different Cassava Varieties

Abstract

Abstract: The activity change of peroxidase(POD), superoxidedismutase(SOD), catalase (CAT) and the content of malondialdehyde(MAD) in five cassava varieties during the senescence of cassava were by studied . The result indicated that the activity change of POD was different in cassava swollen period in October, with maturity of various cassava varieties the POD activity were constantly increased in November; the CAT activity descended with cassava maturity ; the SOD activity and MAD content went up in the cassava swollen period, and went down with cassava maturity. The synthesis comparison of various senescence index, the order was GR891>Baxizhong >SC124 >Nanyanghong>GR911.
