摘要 在高温、高湿模拟条件下人工加速老化的黄瓜种子,生活力与活力指标均发生明显变化,电导率随老化程度增大而呈平行关系,种子乙烯含量随老化程度增大而呈规律性下降,乙烯释放高峰期推迟。种子贮藏物质中,可溶性糖与淀粉含量减少,过氧化氢酶与脱氢酶活性随种子老化程度的增加有下降的趋势。 Significant viability and vigor changes were found in cucumber seeds during artificial aging. Electrical conductivity appeared to be the paralleled relations in the case of high temperature and high wet simulation, while ethylene level of seeds decreased regularly with aging degree increases, and the ethylene releasing peak was delayed. In seed storage materials, suluble sugar and starch contents decreased greatly, while hydrogen peroxidase and gehydrogenase showed a tendency of decrease as seed degree increases.
