| 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。 |
| 关 键 词： | 异叶爬山虎 栓翅爬山虎 五叶爬山虎 耐荫性 生态型 |

| Abstract: | 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. |
| Keywords: | Parthenocissus dalzielii P suberosa P quinquenfolia shade-tolerance ecotype |
