摘要
通过不同程度遮荫处理对细叶百合和松叶百合的生长特性、解剖结构及光合色素含量的变化规律进行研究。结果表明,遮荫条件下两种百合的株高、叶面积、株高/茎粗和叶绿素含量均高于对照;叶干重/叶鲜重比值均低于对照。遮荫处理后细叶百合叶片厚度、栅栏组织厚度、海绵组织厚度大于对照,松叶百合则小于对照。
This experiment was investigated the change rule on growth, anatomical structure and photosynthetic pigment content of Lilium pumilum and Lilium cemuum under different shading treatments. The results showed that the plant height, leaf area, plant heightstem diameter and chlorophyll content of two species were all higher than that of the control, however, the ratio of DW/FW was all lower than that of the control. The leaf thickness, spongy tissue, palisade tissue of Lilium pumilum was higher than that of the control after shading. In contrast, Lilium cemuum was lower.
