| 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下贮藏效果进行了研究。结果表明，超干孵：藏町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蛋白质谱带尤显著差异。 |

| Studies on spinach seeds' physiological characteristics of aging-resistance after ultra-dry storage |
|

| 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. |
