植物根系生物学研究进展

根系生物学是近十几年来兴起的一门专门研究植物根系的前沿学科，研究领域涉及形态学、生理学、发育生物学、分子生物学、遗传学等多个学科。根系生物学是重要的生态和农业指标，对于保护和利用植物资源、改良植物遗传品质和提高植物生产力具有重要的指导作用。文中从根系构型、根系生长发育与环境、根际、根系解剖结构以及根系遗传改良等方面总结归纳植物根系生物学的研究进展，阐明根系生物学的研究意义，在探讨当前根系生物学研究存在问题的基础上提出今后研究建议。

Research Advance of Plant Root Biology

The root biology is a cross-cutting discipline focused on the research on plant root system that has emerged in a decade. Its research areas cover morphology, physiology, developmental biology, molecular biology and genetics. Root biology as the important ecological and agricultural index plays important guiding role in protecting and utilizing plant resources, improving genetic quality of plants and increasing productivity. This paper summarized the research advance of plant root biology in recent years in terms of root architecture, root growth and soil conditions, rhizosphere, anatomical structure of root and genetic improvementof root. Meanwhile it clarified the significance for studying root biology and discussed the problems arising in recent research. Finally, some suggestions were put forward for the future development of root biology.
