摘　　要：硼作为植物的必需营养元素,对植物的许多生理过程起着重要的作用。根系是植物地下的营养器官,决定着地上部及整个植株的生长发育。本文对近年来国内外学者在植物根系方面硼素营养的一些研究成果进行综述,着重阐述了低硼胁迫下植物调控根系生长和养分吸收的机制,以及硼对根系细胞壁结构的形成及稳定、豆科植物根瘤的生长发育及根瘤菌的固氮能力等方面的重要作用,最后提出了应加强硼元素在植物根系方面研究的问题与展望。Boron is an essential nutrient element for plant and plays an important role in many physiological processes of higher plants.Root is an important organ for absorbing the water and nutrients, and affects the growth and development of plants.This review is focused on recent researches about the regulation and physiological metabolism of roots under boron deficiency,the regulatory mechanism of root growth and nutrition absorption under low boron condition.In addition,this paper summarized effects of boron on stability of root cell walls,growth and development and nitrogen fixing capacity of root nodule of leguminous plants.Finally,problems and prospects of researches about the effects of boron on plant roots were proposed.
