热带园林4种木质藤本植物叶性状与环境适应能力研究
|
摘要
为了探究不同木质藤本植物对环境变化的适应能力,以紫萼龙吐珠、狭叶异翅藤、蒜香藤和炮仗花4种常见的热带园林木质藤本植物为研究对象,通过测定叶片的10个性状,利用方差分析、主成分分析、模糊隶属函数分析探讨4种木质藤本植物对环境适应能力的强弱。结果表明:紫萼龙吐珠的比叶体积、叶绿素a含量、叶绿素b含量和叶绿素含量均高于其他3种植物;在叶经济谱中,狭叶异翅藤、蒜香藤和炮仗花在资源轴上属于"快速投资—收益"型物种,紫萼龙吐珠在资源轴上属于"缓慢投资—收益"型物种;4种木质藤本植物的环境适应能力从强到弱分别为紫萼龙吐珠、炮仗花、蒜香藤、狭叶异翅藤。
To assess the leaf traits of different lianas response to environment, 4 common tropical landscape lianas, Clerodendrum speciosum, Hetcropterys angustifolia, Mansoa Alliacea and Pyrostegia venusta were chosen to investigate the 10 leaf traits and analyze their relationships between leaf trait and environment. The methods of ANOVA, principal component analysis and fuzzy membership function were used to evaluate the environmental adaptability of 4 lianas. The results show that the values of specific leaf volume chlorophyll a content, chlorophyll b content, and chlorophyll content in Clerodendrum speciosum are significantly higher than other species.According to the leaf economic spectrum, the species at the quick investment-return end is Clerodendrum speciosum while other three species are at the slow investment-return end. The rank of environmental adaptability of4 lianas from high to low as Clerodendrum speciosum, Pyrostegia venusta, Mansoa alliacea and Hetcropterys angustifolia.
