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上升;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处理有利于板栗的保鲜贮藏.
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.
