棉花涝害胁迫研究综述

A Review of Cotton Waterlogging Stress

涝害是棉花生产中面临的重要自然灾害之一,严重制约了棉花种植面积和产量。为了研究涝渍灾害对棉花生长发育状况的影响,本研究从棉花的形态生长、生理特性及植物激素变化等方面概述了涝害胁迫的研究现状及进展,分析了涝害对棉花生理机制造成的影响,以及涝害胁迫下棉花通气组织的形成及酶代谢适应性变化,并就棉花耐涝性鉴定方法、评价指标及其品种选育等提出了需要进一步研究和探讨的建议。

Waterlogging is waterlogging which severely of waterlogging on one of the main abiotic stresses in nature, and cotton is constantly exposed to restrict cotton planting acreage and lint yield. In order to study the harmful effects the growth and development of cotton, we summarized present situation and progress of studies on waterlogging stress in terms of morphological parameters, physiological traits and phytohormone variation, and then analyzed cotton physiological mechanisms under waterlogging stress, including adaptive changes of cotton aerenchyma formation and enzymes metabolisms, and lastly gave several advices on waterlogging identification methods, evaluating indicators and varieties breeding for further study.
