摘要
本研究以油菜叶片为材料,对其含水量、叶绿素含量、丙二醛含量、过氧化氢酶活性等生理指标进行测试分析。试验结果表明:相对于全光照的油菜而言,遮荫处理后叶片的含水量显著上升;不同光强处理对叶绿素含量也存在影响:遮荫处理后叶绿素总量、chla、chlb的含量均上升,但chla/chlb下降;遮荫后叶片的丙二醛含量有所上升,但过氧化氢酶活性稍微下降。
Leave physiological activity were studied with Brassica campestris L. planted in pot. The result showed： Compared to those under 100% sunlight, the plants which were treated by shading showed that water content of leaves were increased remarkably.The effect of treatments with different light-intensity significant with the performance of the increase of contents of total chlorophyll, chlorophyll a and chlorophyll b, meanwhile the chlorophyll a/b decreased.And with the decreased of lightintensity, the content of malonyldialdehyde （ MDA ） increased, but the activities of catalase （ CAT ） decreased.
