| 摘 要： | 银杏种子不耐脱水，属于温带非典型性顽拗型种子，在干燥脱水过程中，胚和胚乳的超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性呈现出降低－升高－降低的变化趋势；过氧化物酶(POD)活性以及丙二醛(MDA)含量先上升后下降；种子浸泡液的电导率不断增加，活力不断降低。

| Abstract: | The Ginkgo Biloba Seeds were desiccation-sensitive when shedded. With the lost of water, the change tendency of superoxide dismutase (SOD) and catalase (CAT) was decreased-increasde-decreased. The Activity of peroxidase (POD) and the content of malonaldehyde (MDA) increased at the earth desiccation stage, then it decreased with dehydration. The rate of electrolyte leakage increased and seed vigor decreased rapidly. |
