摘　　要：在植物的生长过程中,干旱是制约其生长发育和产量的重要因素。腐殖酸(HA)对植物的生长发育及耐旱性有着重要作用,广泛参与调控植株防御反应和形态发育相关的多种生物学过程,应对各种环境胁迫的应激反应。文章着重介绍了干旱胁迫下腐殖酸对植物的表观形态、生理生化、分子机制等方面影响的研究进展,腐殖酸对干旱胁迫下植物表观形态的影响主要体现在根系和地上植株的生长发育,而植物生理水平的影响主要体现在光合作用、渗透调节代谢、抗氧化代谢、激素物质以及矿质营养等方面,并阐述了腐殖酸诱导的分子机制及参与其中的调控基因,总结了当前腐殖酸研究中存在的问题,对腐殖酸在植物抗旱性上的应用前景进行了展望。In the process of plant growth,drought is an important factor restricting growth,development and yield.Humic acid (HA) plays an important role in many biological processes related to plant defense responses and morphological development.In this review,the effects of humic acid on plant morphology,physiology,biochemistry and molecular mechanisms under drought stress are reviewed.The effects of humic acid on the growth and development of plant roots and above ground plant parts under drought stress,and its effects at the plant physiological level on photosynthesis,osmotic regulation,antioxidative metabolism,hormones and mineral nutrition are discussed.The existing problems in the research of humic acid are summarized and the prospects for the application of humic acid in plant drought resistance are examined.
