| 摘 要： | 通过盆栽试验研究了模拟渍水条件对苗期油菜（Brassica napus L.）中双11号生长及生理特性的影响。结果表明，渍水超过3 d就会显著抑制苗期油菜的生长，这与渍水降低油菜叶片叶绿体和光合色素含量、降低氮素吸收利用和引起过氧化胁迫有关。渍水后苗期油菜的生理恢复，无论是叶绿体和光合色素含量，还是硝酸还原酶及抗氧化酶活性的恢复均表现出一定的滞后性，而且渍水时间越长滞后期越长。此外，在苗期油菜叶片光合色素中，渍水对类胡萝卜素的影响要大于对叶绿素的影响。

| Abstract: | A pot experiment was conducted to investigate the effects of waterlogging on the growth and physiological properties of juvenile oilseed rape (Brassica napus L. cv. Zhongshuang No. 11). Waterlogging lasted 3 or more days significantly depressed the plant growth, which might be due to it decreased the chloroplast and photosynthetic pigment content, nitrogen uptake and utilization, and induced the oxidization of plant. The effects of waterlogging on juvenile oilseed rape growth is mainly attributed to its influence on the recovery process of physiological properties after flooding, which was prolonged with the period of waterlogging lasted, including the chloroplast and photosynthetic pigment content, nitrate reductase and antioxidant enzyme activities. Moreover, in photosynthetic pigment, the effect of waterlogging on the carotenoid content was more significant than chlorophyll content of juvenile oilseed rape. |
