干旱和高温对植物胁迫效应的研究进展

干旱对植物的影响广泛而深刻，它可以表现在生长发育的各个阶段，如种子萌发、营养生长和生殖生长，直到开花结实．同时影响各种生理代谢过程，如光合作用、呼吸代谢、水分和营养元素的吸收转运、各种酶的活性和有机物质的转化、运输、积累等．本文概述了植物体对水分和高温胁迫做出的响应，既有生理上的，包括光合作用，呼吸作用，气孔行为等，又有形态结构方面的适应，并讨论了研究中存在的问题及对未来的展望．

Plant Responses to the High Temperature and Moisture Stress

Drought stress and high temperature influence plant activities and processes in germination, development, bloom and burliness widely and deeply. They can show in every stage of growing of the botanical, such as sprout of the seed, growing of the nutrition and growing of the generation. Moreover, physiological process of metabolism, such as photosynthesis, respiration, absorption and transportation of water and nutrients, activities of enzymes, and transformation, transportation, and accumulation of metabolic products, are closely linked with moisture and temperature regimes of micro - environment. Advances on stress ecophysiology researzh are summarized in this paper. Responses of plant to environment stress conditions and their physiological, morphological, ecological adaptability are presented. The problems and present studies and potential hotspots are also discussed.
