摘  要:
研究了不同遮荫水平(遮光率分别为:0%、50%、75%、90%、98%)对山蒟部分形态和生理指标的影响。结果表明,随着遮荫率的提高,山蒟在适度低光照(50%~75%遮荫)水平下,茎生长量、叶面积、植株含水量、叶绿素含量增加,比叶重减小。叶绿素总量增加,尤其是叶绿素b含量增加,光合性能提高,光合产物的积累增加,表现出对弱光环境的适应,75%遮荫处理最有利于山蒟的正常生长。山蒟可作为一种新优耐荫园林植物在立交桥下、高层建筑物之间、林荫下等弱光环境中种植。

摘  要:
The effects of different shading levels(shading levels of 0%,50%,75%,90%,98%) on morphological and physiological characteristics of Piper hancei seedlings were investigated.The results showed that,on a proper illumination level(50%~75% under shade),the growth of stem,leaf area,water content of plant,chlorophyll content and total amount increased,but specific leaf mass(SLM) declined with shading levels increasing,specially,chlorophyll b content increased.These resopnses could improve the photosynthetic efficiency,photosynthetic production accumulation and the adaptability of Piper hancei under the weak light environment.Piper hancei seedlings grew best at the 75% shading level.It could be taken as a new shade garden plants for cultivation under the overpass,between the high-rise buildings,tree-lined and other low-light environment.
