摘要:

土壤盐碱化问题日益严峻,已经成为全球范围内制约植物生长发育的主要环境因子之一。根系在植物应答逆境胁迫中具有重要的调节作用,但是多年来对于植物抗逆性的研究往往集中于地上,根系作为环境胁迫下最先感知并作出反应的器官,其耐逆机理还不明确。基于此,本文从根系构型、结构、生长、生理和分子生物学等多角度对国内外植物根系应答土壤盐碱胁迫机理进行了综述,并提出了不足与展望,旨为深层次揭示植物根系功能和耐盐碱胁迫机理提供一定的科学依据。

Abstract:

As one of the serious environmental factors, soil salinization has severely restricted plant growth and development worldwide. Root system plays significant role in the regulation of plant responded to stress. However, most previous studies about plant stress tolerance focused on the aboveground. As the first organ to perceive and response to the environmental stress, stress tolerance of root system was still unclear. For this reason, the mechanism of plant roots responded to soil saline-alkali stress was summarized from the perspectives of root system architecture, structure, growth, physiology and molecular biology, and shortcomings and prospects were also put forward in this manuscript. The aim was to provide a scientific basis for further revealing the function of plant root system and its saline-alkali stress tolerance mechanism.

Key words: root, salt stress, alkaline stress, root architecture, physiological mechanism
