遮光对丽莎蕨生长与一些生理的影响

Effect of Shading Treatments on Growth and Some Physiological Effects in Rumohra adiantiformis

设置50％遮光及7O％遮光处理，研究不同遮光水平对丽莎蕨叶片生长、产量及一些生理效应的影响，结果表明，7O％遮光处理比50％遮光处理，能促进叶片的生长，增加其商品产量，同时能提高叶片的叶绿素a、b及总叶绿素的含量，明显增加POD活性及叶片中K的含量；对叶片的解剖结构无明显影响，但能明显促进细胞内含物的积累。

Effects of 50% and 70% shading on the growth, yield and physiology of Rumohra adiantiformis were studied. The results indicated that 70% shading treatment, in comparison with 50%shading treatment, had more obvious effect in promoting leaf growth, increasing market yield, and could raise the contents of chlorophyll a, b and total chlorophyll. The POD activity and content of K in leaves could be apparendy increased in 70% shading treatment; No obvious effect on anatomical structure of leaf, but it could apparently accelerate accumulation of cellular matters on the leaves of 70% shading treatment than that of 50% shading treatment.
