摘　　要：以蟹爪兰和盆栽榕树这2种花卉为研究对象,通过设置4种遮阴梯度光照时间处理(遮阴时长分别为15,30,45,60 d),分别测定遮阴后2种植物的生长指标、细胞内的相对质膜透性及叶绿素含量。结果表明,随着遮阴时间持续增加,蟹爪兰和盆栽榕树这2种植物的叶片长度、宽度及叶面积、株高都比正常光照下生长快速,叶绿素含量也随着遮阴时间增加而上升,细胞内的质膜透性随着遮阴时间的增加而下降。说明蟹爪兰和榕树这2种花卉均有较高的耐阴性,夏季光照强度大时应进行适当遮阴。In this study, taking two kinds of potted plants crab cactus and banyan as research object, 4 kinds of shading lightingtime treatment （shading treatment time were 15, 30, 45, 60, respectively）were set up, and growth index, relative membrane permeabilityin cells, and chlorophorll contents were measured. The results showed that with the increasement of shading time, the length, width andarea of leaf, plant height and the contents of chlorophyll were increased, whereas, the membrane permeability in cells were decreased,compared with those plants under the normal sunlight. It indicates the crab cactus and banyan have higher tolerance of shade. It isadvisable to adopt shading treatment during the strong sunlight period in summer.
