摘要：水分作为植物生存、生长和发育的主要限制因子,会通过植物生理过程和状态的变化来影响植物生长和产量。为阐明植物在干旱环境下适应性变化,该文主要综述了植物在干旱胁迫下生长、叶绿素含量、光合参数、保护酶活性的变化情况,并提出了几点研究展望,如在今后的试验中可采用顶棚法模拟干旱,使试验环境更真实,结果更可靠;探究在严重干旱或持久干旱下,植物光合作用代谢机制的变化情况;以及探究长期干旱胁迫下常绿植物在不同季节下光合能力的变化。
Water is a main limiting factor in plant survival, growth and development, as which can affect plant growth and yield through the physiological process and state. In order to clarify the adaptations of plants in drought environment, the changes in grow-th, the chlorophyll content, photosynthetic parameters and protective enzyme activities under drought stress were mainly reviewed in this article. In addition, such several research prospects were focused on as to simulate drought by using throughfall exclusion in future experiments in order to make experimental environment more real and results more reli-able ,to explore the changes in plant photosynthetic metabolism in serious drought or in continuous drought, and to inquire the changes in photosynthetic ability of evergreen plants in different season during continuous drought.
