植物叶寿命测定方法综述

叶寿命是一个反映植物行为和功能的综合性指标,与植物资源利用、物候学和生长策略密切相关。叶寿命的相关研究可追溯到20世纪初,尽管叶寿命的研究已经长达一个世纪,但目前仍然缺少公认的测定叶寿命的方法。为此,在概述叶寿命研究历程的基础上,分析并总结了国内外专家学者对于叶寿命的不同测定方法,包括生命表法、传统的野外标记观测方法和野外监测与叶寿命模型结合的方法,以期为植物物候和功能性状的研究提供帮助。

A Review on Methods for Measuring Plant Leaf Longevity

Leaf longevity is a comprehensive indicator to reflect the behavior and function of the plant,and is closely related to the utilization of plant resources,phenology and growth strategies.It is also a key factor affecting nutrient cycling and productivity of ecosystem,which links the physiological and ecological processes of leaves,individual plant growth and ecosystem processes.The research on leaf longevity can date from the beginning of the early 20th century.Although the research on leaf longevity had lasted for over a century,there is still a lack of a common method to measure leaf longevity that would be widely used.This review summarized the development history and the different measured methods of leaf longevity,which will greatly promote the studies in plant phenology and functional traits.
