摘要
叶片是水分传输的终端部分,水分在叶片中的传输效率限制了整个植株的水分传输,而叶片水力性状可以表征叶片水分传输方面的特征。目前针对叶片水力性状开展了较多研究并取得了一定的成果。文章在简述叶片水力性状测定指标、测定方法的基础上,阐明了影响叶片水力性状的因素、水力性状之间的权衡和协调关系以及与光合生理过程的响应关系;重点概述了气候变化背景下叶片水力性状的响应机制,并展望了今后的研究重点,以期为进一步了解植物碳水耦合关系提供参考。
Hydraulic characteristics of leaves can represent the features of leaf water transport since leaves are the terminal part of water transportation.Leaf water transport efficiency can constrain the whole plant's water transport.At present,many studies have been conducted on the leaf hydraulic traits of leaves and some results have been obtained.Based on a brief description of leaf hydraulic traits measurement indicators and methods,we discussed the factors affecting leaf hydraulic traits,trade-offs and coordination between hydraulic traits and their response to photosynthetic physiological processes.We focuses on the response mechanism of leaf hydraulic traits under the context of climate change.The future research is prospected,hoping to provide a reference to further understanding of the coupling relationship between carbon and water.
