摘要: 植物叶片的水分传输是SPAC系统中的一个重要环节,不仅受植物本身的调节和控制,而且还受外界环境条件的影响,是复杂的生理过程。为了搞清SPAC系统水分传输机理,人们对植物叶片导水率进行了大量的研究。本文综述了近年来植物体叶片导水率研究的一些新的进展和发展动态,就叶片水分传输在植物水分平衡中的作用、叶片导水率的定义及其影响因素等方面进行了综述。影响植物叶片导水率的内部、外部环境因素各异,文章重点阐述了土壤因素、气象因素、植物激素、生育阶段和解剖特性等对叶片导水率的影响,提出植物叶片导水率研究中亟需考虑的问题,并对今后SPAC系统中叶片导水率研究的重点发展方向做了展望。

Abstract: Leaf water transport is a complex physiological process in the SPAC system. It is not only regulated by the plant itself, but also affected by the external environmental conditions. This paper reviews recent new progresses and developments including the role of leaf water transport in plant water balance, the definition of leaf hydraulic conductivity and its influencing factors. Internal and external environmental factors differ in affecting leaf hydraulic conductivity. This paper mainly explains the effects of soil factors, meteorological factors, plant hormones, developmental stages and anatomical characteristics on leaf hydraulic conductivity. At last, we put forward some urgent problems needing to be considered in leaf hydraulic conductivity research and made prospects for key development direction of research in the future.
