摘要：

以东京夏黑和潼光一本太大葱为试材，研究了大葱对不同遮光处理的形态和生理反应。结果表明：两种遮光处理均使供试大葱品种的株高，含水量，叶绿素含量以及Vc含量增加，而使可溶性糖含量减少。不同遮光程度对茎粗影响不同: 与对照相比，遮白网使茎粗增加，遮黑网使茎粗减小。大葱生产中可依据实际情况而采取不同遮荫处理,以达到最佳产量和品质指标。

Abstract:

The morphological and physiological responses of two Welsh onion cultivars, e.g. Dongjingxiahei and Tongguangyibentai, to different degree of shading, were studied. The results showed that the plant height, water content, chlorophyll content and Vc content were increased after the two shading treatment, respectively. However the content of soluble sugar was declined. The stem diameter responded differently to different degree of shading.
