遮光处理对女贞叶色及生理指标的影响

Effect of Shading Treatment on Leaf Color and Physiological Indices of Ligustrum lucidum

通过对不同遮光处理下女贞叶色及生理指标的变化情况的比较分析,结果表明:高强度的光照条件下女贞叶片中叶绿素含量低,颜色多为金黄色;弱光下叶片中叶绿素含量高,叶片的颜色多为黄绿或者绿。较低的光照条件对女贞叶色的变化不利。我国北方地区栽植女贞时要保证较强的光照,避免在高大的树木或者建筑物周围栽植。

The changes of leaf color&physiological indexes under different shading were compared.Result shows that the chlorophyll content is low&the color is mostly golden yellow under high intensity illumination conditions.The chlorophyll content in the weak light leaves is high,and the color of the leaves is mostly yellow-green or green.It can be seen that the lower light conditions are unfavorable to the expression of the leaf color of Ligustrum lucidum.It is suggested that when planting Ligustrum lucidum in the northern part of China,it is necessary to ensure strong light,avoid planting around tall trees or buildings.
