摘　　要：研究O2 、CO2 、N2 、SO2 对银杏种子贮藏过程中霉变率、呼吸强度、失水率、硬化率、胚生长、过氧化氢酶 (CAT)、过氧化物酶 (POD)、果胶甲酯酶(PE)的影响。结果表明 ,在 3%～ 5 %O2 、 3%～ 5 %CO2 、 >70 %N2 和 >1 0 %SO2的气调状态下 ,贮藏银杏种子效果良好。CO2 和N2 对上述 3种酶的作用较小。随O2 浓度增加 ,CAT和POD活性下降 ,而PE活性基本不变。SO2 对 3种酶均有较强的抑制作用。This paper studied the effects of O 2,CO 2,N 2 and SO 2 on rotting rate,respiratory intensity (RI),hardening rate,embryo growing,water lose,and the activities of catalase(CAT),pectinesterase(PE),and peroxidase(POD)of Ginkgo seeds during storage.The results showed that under the satisfied storage conditions of the gas composition of 3%～5% O 2+3%～5%CO 2+>70%N 2+>10%SO 2,the storage effect of ginkgo seed was better.In addition,there was little effect of CO 2 and N 2 on CAT,PE and POD,and its activities became lower with the increase of O 2 concentration,but PE activity was almost unchanged.CAT,POD and PE could be strongly inhibited by SO 2.
