板栗贮藏过程中的生理生化变化初探

Physiological Studies on the Chestnut During Storage

摘要: 用阳山油栗为试验材料，在贮藏过程中，呼吸作用随着贮藏时间的延长而逐渐下降，栗果失重率总的趋势是随着贮藏时间的延长呈不断上升之势；超氧化物歧化酶（ＳＯＤ）酶活性前期保持在一个比较高的水平，后期逐渐下降，而过氧化物酶（ＰＯＤ）、过氧化氢酶（ＣＡＴ）酶活性则随着贮藏时间的延长而逐渐升高最后又下降；电导率前期较低而后期逐渐下升；低温＋Ｃａ处理的ＳＯＤ及ＰＯＤ同工酶均比＋Ｈ２Ｏ处理的多１条酶带、低温＋Ｃａ处

Abstract: The physiological changes of Yangshan chestnut (Castanea mollissia Blume) during storage were studied. Respiratory rate dropped with the the. The activity of superoxide dismutase (SOD) remained at a higher level in the preliminary phase (about 60 days after storage), and thereafter dropped,whereas the activities of peroxidase (POD), catalase (CAT) increased gradually. The electrical conductivity kept at a lower level during the preliminary phase (about 60 days after storage), and then increased.
