克隆植物的水分生理整合及其生态效应

水分生理整合是克隆植物生理整合过程中非常重要的一部分,是克隆植物生长发育和生态适应过程中的重要机制之一。本文主要从理论上对克隆植物水分生理整合的存在性、方向性、整合的程度、范围及其与克隆植物的功能分工、表型可塑性和觅养行为、风险分摊等行为表现的关系进行了深入分析,并对迄今有关克隆植物水分整合的最新研究进展和研究方法进行了系统总结和评述。提出克隆植物的水分生理整合包括水平和垂直两个方向,而水力提降为垂直方向的水分生理整合提供了一个重要途径。认为在今后,应加强对克隆植物水分生理整合的精确定量化研究,同时,应运用生态学、生理学、生物化学及分子生物学等方法,综合深入地研究克隆植物水分整合的机理。

Water Physiology Integration and Its Ecological Effect of Clonal Plants

Water physiology integration is an important part of the physiological integration of clonal plants and one of the important mechanisms in the growth,development and adaptation of clonal plants.The paper present an in-depth analysis about existence possibility,orientation,degree,limits of water physiology integration of clonal plants and their relation to such behaviors as functional differentiation,phenotypic plasticity and foraging behavior and risk spreading,and systematically summarizes and comments on the latest research advances about water integration of clonal plants.It points out that water physiology integration of clonal plants includes vertical and horizontal directions and hydraulic lifting and lowering provides an important way for vertical water physiology.It holds that it is necessary to strengthen quantitative researches about water physiology integration of clonal plants and carry out in-depth researches about water-integration mechanisms of clonal plants by employing the methods in ecology,physiology,biochemistry and molecular biology.
