摘要
为探讨爬山虎属植物的耐荫特性,设置了3个不同的遮光水平(遮光度分别为:0、37和78%)对异叶爬山虎、栓翅爬山虎和五叶爬山虎的23个不同生态型进行了耐荫性研究。研究结果表明:异叶爬山虎具有良好的耐荫特性,其中尤以广州天河异叶爬山虎生态型耐荫性最强,所使用的各指标中,比叶面积最能反映爬山虎植物的耐阴性。
Seventeen, five and one ecotypes of P. dalzielii, P. suberosa and P. quinquenfolia, respectively, were collected from 5 provinces in southern and middle parts of China, and their shade-tolerance was investigated. The plants were stressed under 2 shading treatments （shading ratio were 37% and 78%, respectively） and a control with zero shading was also conducted. The results showed that the shade-tolerance of P. dalzielii was higher than that of P. suberosa and P. quinquenfolia. The ecotypes collected from Tianhe district, Guangzhou City, Guangdong Province were with the highest shade-tolerance. Among characters tested, ratio of leaf area/dry weight value were found to be coincident with the actual shade-tolerance of the tested ecotypes, and therefore were considered to be useful for evaluating the shade-tolerance of plants of Parthenocissus spp.
