植物根系研究进展

Research Advances on Plant Roots

根系是植物体的地下部分,是植物长期适应陆地条件而形成的一个重要器官,具有锚定植物、吸收输导土壤中的水分养分、合成和储藏营养物质等生理功能。根的发育过程比较复杂,而且因不同种类的植物和环境条件而异,形成了不同的根系类型、形态结构、生理功能及生长特性。现对植物根系的生理机制、根系活力、根系环境胁迫及根系的形态构型等进行了概述。

Root system is the underground part of plants,and an important organ formed in long-term adaptation on land. It is with physiological functions of anchoring plant, absorbing water and nutrition in soil, synthesizing and reserving nutrition and so on. Root development process is more complex,and varies for different kinds of plants and environmental conditions. It forms different types, structures, physiological functions and growth characteristics of root system.
