摘要: 为保持桑葚采后品质,延长桑葚的贮藏期,研究采后低温(0~2℃)条件正己醇处理对桑葚呼吸强度、VC、过氧化物酶(POD)、脂氧合酶(LOX)、超氧化物歧化酶(SOD)和过氧化氢酶(CAT)的影响。结果表明:正已醇可以降低桑葚的呼吸强度和LOX比活力;延缓桑葚VC的减少;保持POD和CAT比活力;对SOD比活力影响则前后不一,前4d降低了桑葚中SOD比活力,4d后则提高了桑葚中SOD比活力,但各处理与对照差异不显著。

Abstract: In order to achieve an optimal method for maintaining post-harvest quality and extending storage period of mulberry fruits, the effect of 1-hexanol treatment on respiratory intensity, vitamin C, peroxidase (POD), lipoxygenase (LOX), superoxide dismutase (SOD) and catalase (CAT) in mulberry fruits stored at low temperature of 0-2 ℃ was explored. The results indicated that 1-hexanol could reduce respiratory intensity and LOX activity, delay the reduction of vitamin C, and maintain POD and CAT activities of mulberry fruits. However, the 1-hexanol treatment could result in the reduction of SOD activity during first 4 days and increase after 4 days.

Key words: mulberry, 1-hexanol, antioxidant enzyme, senescence
