摘　　要：以华南地区9种木质藤本和5种草质藤本为研究对象,通过测量全阳和荫蔽环境下2类藤本叶性状指标,研究其叶性状差异及相关性,分析其叶经济谱并探讨2类藤本对不同光环境的适应性策略及应用。结果表明:14种藤本植物在不同光环境中表现出不同的适应策略,总体表现为采取SLA升高、LT降低、LWC提升、LDMC降低等策略来适应荫蔽环境。草质藤本的SLA极显著高于木质藤本,而木质藤本的LDMC极显著高于草质藤本,草质藤本在叶经济谱中更倾向于“快速投资−收益”型物种,木质藤本则更倾向于“缓慢投资−收益”型物种。叶功能性状SLA、LNC、LD、LDMC、LWC间紧密相关,表现出SLA与LDMC、LD呈极显著负相关,与LNC、LWC呈极显著正相关的权衡关系。聚类结果显示,绿萝和合果芋为耐荫植物,五爪金龙、鸡矢藤、珊瑚藤、玉叶金花、炮仗花、锦屏藤、冬红为中性偏阳植物,鹰爪花、络石、软枝黄蝉、叶子花、白花油麻藤为喜阳植物。Taking 9 kinds of lianas and 5 kinds of herbaceous vines in South China as the research objects,by measuring the leaf trait indicators of 2 types of vines under full sun and shade environments,the differences and correlations of their leaf traits were studied,and their leaf economic spectrum was analyzed and discussed in depth.The results showed that the 14 vines exhibited different adaptation strategies in adapting to different light environments,and the overall performance was to adapt to the shady environment by adopting strategies such as expanding SLA,reducing LT,increasing LWC,and reducing LDMC.The SLA of herbaceous vines was significantly higher than that of lianas,while the LDMC of lianas was significantly higher than that of herbaceous vines.Leaf functional traits SLA,LNC,LD,LDMC,and LWC were closely correlated.It showed a trade-off relationship that SLA was extremely significantly negatively correlated with LDMC and LD,and extremely significantly positively correlated with LNC and LWC.The clustering results show that Epipremnum aureum and Syngonium podophyllum are shade-tolerant plants,and Ipomoea cairica,Paederia scandens,Antigonon leptopus,Mussaenda pubescens,Pyrostegia venusta,Cissus verticillata and Holmskioldia sanguinea are the neutral partial-sun plants,and Artabotrys hexapetalus,Trachelospermum jasminoid,Allemanda cathartica,Bougainvillea sp.and Mucuna birdwoodiana linseed vines are sun-loving plants.
