摘　　要：根系是土壤和植物的动态界面,植物根系具有锚定植株、吸收和运输土壤中的水分及养分、合成和贮藏营养物质等重要功能。近年来,随着研究方法的改进和现代根系定量分析技术的发展,对根系的研究日益受到重视和关注。因而,根系的研究在多个新的研究方向上展开。本文简要介绍了国内外近年来在根系对土壤环境胁迫响应的研究进展,以供根系研究参考。Roots are a dynamic interface of soil and plant. Plant roots can anchor plants, absorb and transport water and nutrients in soil, synthesis and storage of nutrients and other important functions. In recent years, the research methods are improved and the technology of the modern roots quantitative analysis is developed, and then the research of roots are obtained attention. Thus there are a number of new research directions. This paper introduced the advances of research in roots at home and abroad in recent years. It also included roots responses to environmental stress on soil to provide reference for research on root systems.
