| 摘 要： | 对2年生落叶松幼苗进行不同的遮阴处理,测定华北落叶松叶片内可溶性糖、蛋白质、叶绿素的含量,结果表明：伴随着遮阴程度的增加,可溶性糖与蛋白质含量相应减少。与此同时,为了保护光合作用的正常进行,叶绿素b的含量逐渐增多。华北落叶松幼苗在生长过程中需要充足的光照,但适度的遮阴可促进光合作用的高效进行。

| Abstract: | Different shading treatment on growth of 2 year-old Larix principis-rupprechtii seedlings,soluble sugar,protein and chlorophyll content of leaves were measured.Results showed that:contents of soluble sugar and protein decreased as the increase of shading treatment.At the same time chlorophyll b content in leaves gradually increased to maintain photosynthesis,and physiological parameters in leaves were stable and efficient.The suitable shading treatment on Larix principis-rupprechtii seedlings was to promote the efficient photosynthesis. |
