摘　　要：地理环境差异和自然选择使植物种内产生了广泛的遗传变异,并丰富了遗传多样性。植物为适应逆境环境会产生一系列复杂的生理变化,而同一植物的不同地理种源其生理表现存在着明显差异,这为筛选优良种源提供了基础。文中综述了在盐胁迫、水分胁迫、温度胁迫和低磷胁迫下不同植物地理种源间生理变化的差异,分析了研究中存在的问题,对未来的研究工作提出了展望,以期为植物资源合理利用与保护和科学改良提供科学依据。Geographical variation and natural selection trigger a wide range of genetic variation in plants,which enriches the genetic diversity. In order to adapt to adversity environment,plants will produce a series of complex physiological changes,while the same plants with different geographical provenances will show varied physiological performances,which provides a scientific basis for screening excellent provenances. In this paper,we summarized and reviewed the differences in physiological variation among different geographical provenances under the salt stress,water stress,temperature stress and deficient phosphorus stress. Finally,we analyzed the problems existing in current researches and put forward the prospect of the future studies,with the expectation to provide science basis for rationalized utilization,protection and improvement of plant resources.
