【摘要】 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。更多还原

【Abstract】 Through collecting,sorting out and analyzing research data at home and abroad,we summed up study methods and various identification indexes in drought—resistant crops.According to the growth en- vironment and approaches,we divided study methods into six types.Identification indexes included mor- phological index,growth index,physiological index,metabolic index and biochemical index.Most of these indexes could be used in identifying drought—resistance of crops,while others were not reliable enough because of differences in research or lack of sufficient reports.更多还原
