综合评价甘蔗的抗旱性及其抗旱生理指标

A SYNTHETIC APPRAISAL OF DROUGHT-RESISTANCE OF SUGARCANE AND ITS DROUGHT-RESISTANT PHYSIOLOGY INDEXES

摘要: 用主成分分析方法对７个甘蔗品种（种）的抗旱性和７项抗旱生理指标作了分析．将抗旱生理指标分成３种类型，并对甘蔗品种（种）的抗旱性强弱进行了排序．

Abstract: It was conducted to applying PCA to analyse the drought-resistance of seven sugarcane varieties (species) and seven drought-resistant physiology indexes.Physiology indexes were divided into three types. The drought-resistant ability of seven sugarcane varieties (species) was ranked from strong to weak.
