摘要
研究了4个油菜品种的成熟种子经40℃,100%RH高温高湿、58℃±1℃热水和50%甲醇溶液老化处理后的发芽情况.结果表明:这3种人工老化处理的油菜种子的发芽势、发芽率、发芽指数和活力指数等的变化趋势与自然老化种子的相同,均适用于评价油菜种子耐贮性的人工老化.但58℃±1℃热水和50%甲醇溶液处理比40℃,100%RH高温高湿处理更合适,其最适老化时间分别为10～15分钟和60～100分钟.
Rape seeds of four varieties were artificially aged using the methods of hot water (58℃±1℃), 50% methanol solution and high temperature and humidity (40℃ , 100% RH), respectively. The changeable tendency of all aged seeds in germination potential, germination percentage, germination index and vigour index was similar to that of naturally aged seeds. But the methods of 58℃±1℃ hot water and 50% methanol solution were more suitable than that of 40℃ and 100% RH in evaluating the seed storability and the most appropriate ageing duration were 10～15 minutes and 60～100 minutes, respectively.
