| 摘 要： | 以3个不同白菜品种(‘新早56’、‘新乡小包’、‘北京小杂’)为试材,采用田间试验的方法,研究了干旱胁迫对莲座期白菜生理生化特性的影响,并结合隶属函数法对3个白菜品种的抗旱性进行了综合评价。结果表明:随着干旱胁迫程度的增加,白菜叶片相对含水量、叶绿素含量和净光合速率都明显降低;电导率、丙二醛(MDA)、可溶性糖、脯氨酸的含量则显著增加;不同白菜品种的抗旱性有一定的差异,其中‘新早56’的抗旱性较强,其次为‘新乡小包’和‘北京小杂’。

| Abstract: | Using 3 different Chinese cabbages as experiment material in rosette stage,the effect of drought stress on physiological and biochemical characteristics of Chinese cabbages was studied,and the drought resistance of different Chinese cabbages was evaluated by subordinate function.The result showed that,with the increase of drought stress,leave relative water content,chlonophy content and net photosynthetic rate decreased,while the cell membrane permeation,MDA content,soluble sugar content and proline content increased.The drought resistance in 3 different Chinese cabbages was variable,and the 'Xinzao 56' had higher drought resistance,followed by 'Xinxiang xiaobao' and 'Beijing xiaoza'. |
