摘　　要：为了解不同失水程度对板栗保鲜贮藏的影响机制,以镇安红栗为试验材料,研究了不同失水程度的板栗在贮藏过程中腐烂率、水分含量、电导率、呼吸强度、过氧化氢酶(CAT)、过氧化物酶(POD)和超氧化物歧化酶(SOD)等生理指标的变化。结果表明,失水5%的板栗在贮藏期间的腐烂率、呼吸强度和电导率显著低于对照;CAT、POD和SOD活性维持较高水平。失水10%和15%的板栗在贮藏期间的腐烂率、相对电导率和呼吸强度显著高于对照,POD和SOD显著低于对照、处于低水平。试验表明,板栗采后少量失水对保鲜贮藏有一定的促进作用。The influences of dehydration degree on the decay rate, moisture content, conductivity, respiration rate, Catalase （CAT）, Peroxidase （POD） , superoxide dismutase （SOD） and other physiological indicators of Zhen＇an red chestnuts during storage were investigated. The results show that the decay rate, respiration rate and conductivity of the chestnuts with the 5% dehydration rate during storage were significantly lower than those controlled while CAT and POD activity remained at higher levels and SOD activity decreased slowly. The decay rate, respiration rate and conductivity of the chestnuts with the 10% and 15% dehydration rates during storage were significantly higher than those controlled while CAT, POD and SOD were significantly lower, at a low level.
