| 摘 要： | 从发芽率、保护酶系活性、脱氢酶活性、丙二醛含量和种子蛋白等方面对菠菜种子超干贮藏效果进行了研究。结果表明,超干贮藏可以提高种子的抗老化劣变能力。菠菜种子含水量为3.3%~5.4%时,表现出较强的抗老化和劣变能力及较好的耐藏性。超干和老化处理后菠菜种子的SOD,POD,CAT和脱氢酶活性显著高于原始含水量种子,而丙二醛含量显著低于原始含水量种子。不同含水量菠菜种子的SDS-PAGE蛋白质谱带无显著差异。

| Abstract: | Spinach seeds were used to investigate the ultra-dry effect of aging-resistance.The results showed that ultra-dry seeds became more tolerant to aging conditions.When spinach seeds were dried to about 3.3%-5.4% of moisture content,they became more tolerant to aging and were easier to store.Under the same aging condition,the activity of SOD,POD,CAT and dehydrogenase of ultra-dry seeds were higher while Malonadehyde (MDA) were lower than seeds with original moisture content.The protein of SDS-PAGE bands were almost the same in spinach seeds of different moisture content. |

| Keywords: | spinach seeds ultra-dry storage SOD POD CAT dehydrogenase MDA SDS-PAGE |
