通过对国内外研究结果的收集、整理及分析,总结出作物抗旱的研究方法和可用于作物抗旱性鉴定的各种指标。根据作物生长环境与处理方法将作物抗旱研究方法分成六种,作物抗旱性鉴定指标包括了形态指标、生长指标、生理指标、代谢指标和生化指标共五类,其中绝大部分指标可作为作物抗旱性鉴定指标,少数指标由于研究结果不一致或报道较少,其可靠性尚难以确定,选用时应注意。 Through the collection, collation and analysis of the research results both at home and abroad, the research methods of crop drought resistance and various indexes that can be used to identify the drought resistance of crops are summarized. According to crop growth environment and treatment methods, the research methods of crop drought resistance are divided into six types. The drought resistance identification indexes of crops include five kinds of morphological indexes, growth indexes, physiological indexes, metabolic indexes and biochemical indexes. Most of them can be used as crop drought resistance Identification of sexual indicators, a few indicators of the results of inconsistent or less reported, its reliability is difficult to determine the selection should pay attention.
