棉花主要抗旱鉴定指标研究进展

Research Progress of Major Identification Indicators in the Cotton Drought-resistance

从形态指标、生长发育指标、产量指标、生理指标、生化指标、生态指标,以及综合指标等7个方面,概述国内外有关棉花抗旱性鉴定指标的研究进展,描述棉花各个生育期以及全生育期不同干旱胁迫程度对棉花各方面性状的影响,提出棉花主要抗旱鉴定指标和方法,对生产实践中制定棉花抗旱育种策略和抗旱耕作栽培措施,实现棉花抗旱夺丰收具有实际参考价值。

This paper summarized the research progress home and abroad identification of indicators in the cotton drought-resistance from seven areas of that morphological index,growth and development indicators,output targets,physiological,biochemical,ecological indicators and integrated indicators.It described the various aspects of cotton characters on each growth period and growth period of drought stress.The paper proposed the major identification of indicators and methods in the cotton drought-resistance.It had practical value on making cotton breeding strategies and drought-resistance farming cultivation in actual practices and achieving a bumper harvest of cotton drought-resistance.
