中国农科院作物品种资源研究所于1982年12月22—26日在北京召开农作物品种资源抗旱研究讨论会。会议以交流“三北”地区抗旱鉴定工作为主,并商讨了农作物品种资源抗旱鉴定的方法和指标,以及抗旱鉴定协作内容和方式。会议认为,根据国内测试手段现状,比较可行的生理生化指标是:①用电导法测定细胞膜 Institute of Crop Germplasm Resources, Chinese Academy of Agricultural Sciences in December 1982 22-26 held in Beijing held a variety of varieties of crops Drought Research Symposium. Meeting to exchange “three North” area drought-based identification work, and discussed the identification of drought-resistant varieties of resources identification methods and indicators, as well as identification of drought-resistant content and methods. Meeting that, according to the status quo of domestic test methods, more feasible physiological and biochemical indicators are: ① using conductivity method to determine the cell membrane
