Abstract

Taking Zantedeschia cutting flower as material,we had researched for senescent physiology in vase life(mainly active oxygen metabolism).The results showed that calla cutting flower vase life was about seven days,and superoxide dismutase(SOD),catalase(CAT) activity increased slightly in petal during first two days,and SOD,CAT activities were increased by sugar in 3 th day(distilled water as controll).During vase arrangement,petal peroxidase(POD) activity and malondialdehyde(MDA) content increased continually,but soluble protein content continued decreased.
