41份紫花苜蓿抗旱鉴定试验研究

Study and Appraisal of Drought Resistance Capacity of 41 Different Alfalfa Cultivars

对来自国内外不同种质的41个紫花苜蓿品种进行盆栽试验,测定其7个抗旱鉴定指标,应用系统聚类的方法对数据进行分级聚类,使其归属于3个抗旱等级,分别是:强抗旱、中抗旱和弱抗旱。

By cluster-analysis system,an experiment testing 41 different alfalfa cultivars,planted in pots,from home and abroad for 7 drought resistant indexes proves that the alfalfa cultivars could be classified into 3 drought resistant ranks:the strong drought resistant,the medium drought resistant,and the weak drought resistant.
