【摘要】 研究了大白菜种子人工老化过程中所发生的一系列生理生化变化。结果表明：随着种子老化加深， 种子活力指数、ＰＯＤ、ＳＯＤ、脱氢酶、酸性磷酸酶、脂肪酶活性逐渐降低， ＭＤＡ 及芥子碱含量逐渐增加， 且品种间有差异。认为大白菜种子人工老化及劣变的主要机制在于膜脂过氧化作用加剧。更多还原

【Abstract】 Some physiological and biochemical changes were investigated before and after the artificial aging of Chinese cabbage seeds.The results showed that seed vigor index,activities of SOD,POD,dehydrogenase,acid phosphatase,lipase were reduced gradually with the aging seed;the contents of sinapine in seed exudates and MDA in seed were raised gradually.The main mechanism for deterioration of Chinese cabbage seeds during artificial aging may be the increased peroxidation of membrance lipids.更多还原
