摘　　要：干旱是环境胁迫主要因子之一,严重影响植物的分布与生长发育。本文综述了园林地被植物的根、叶等形态结构特征与抗旱性的关系,总结了干旱胁迫下植物自身的渗透调节、光合生理、膜透性、活性氧代谢对干旱胁迫的响应机理及抗旱分子生物学研究进展。Drought is one of the major environmental stressor, influencing the distribution, growth and development of plant seriously. In this paper, the relations between morphological and anatomical characteristics of root and leaf and drought - resistance were reviewed ; the mechanism of defense responses to drought stress in osmotic adjustment , photosynthesis, membrane permeability and active oxygen metabolism were sunmed up, and also the research progress of drought - resistance molecular biology in this article.
