The best condition of storage and safe time limit were concluded."ZiHua" snap bean of middle maturity during storage at 9 1 shows good results.TKD treatment of 20g/m3 can effectually decrease the occurrence of decay, put off the respiration peak and restrain the decline of quality of snap bean. 6-BA treatment and GA3 treatment can delay the descent of content of Vc, chlorophyll, soluble protein and the rise of coarse fibre of snap bean. The POD activity and respiratory rate of snap beans treated by 6-BA and GAa were significantly reduced and at last reached the purpose of the delaying of spot and decay.

结果表明，中等成熟度的紫花油豆角在9±1℃下贮藏效果较好，低温可减少油豆角锈斑的发生，延缓呼吸高峰的到来，并能抑制油豆角品质的下降。20g／m~3TKD熏蒸处理油豆角可有效减少贮藏期间腐烂的发生，6-BA和GA_3处理可延缓油豆角Vc、叶绿素、可溶性蛋白质含量的下降和粗纤维含量的上升，延缓电导的增加和POD活性的上升，保持较低的膜透性、丙二醛含量，提高豆荚的PAL活性和总酚含量，从而延缓油豆角的衰老，并减少油豆角腐烂和锈斑的发生。
