| 摘 要： | 红花种子经超干处理能显著提高耐藏性及抗老化能力.红花未超干种子(MC=9.01％)经室温贮藏3年，其发芽率，活力指数，脱氢酶活性，过氧化氢酶(CAT)活力和超氧物岐化酶(SOD)活力均有明显下降，而同期室温下贮藏的超干种子(MC=2.18％)其发芽力和活力指数仍保持在原来水平；脱氢酶、CAT、SOD活力保持与低温贮藏种子的同等水平.未超干种子在老化过程中其营养贮藏物较多被消耗，而超干种子保存较好.

| Abstract: | Storage tolerance and aging resistance of seeds were investigated with safflower seed rich in linolic acid After storage at room temperature, seed viability, seed vigor, activity of dehydrogenase, catalase(CAT), superoxide dismutase(SOD) were determinied The results showed that ultradried seed became more tolerant ,compaired to non ultradried seed under storage at room temperature No significant change can be found either in germination rate or seed vigor after storage at room temperature for three years The active oxygen scavenging system and reserve materials were retained well during storage in ultradried state |
