摘要:2016年3月至2016年11月,在川西北地区不同海拔梯度对西康扁桃野生种质资源进行调查,松潘与九寨沟样方的西康扁桃除平均单枝基径外,其它性状均不存在显著性差异。采用主成分分析法对15个指标进行分析,性状累积方差贡献率达到85%进行降维,并对西康扁桃优树综合评选,为四川地区西康扁桃的优树资源筛选奠定了基础。
In this paper, the natural germplasm resources of Amygdalus tangutica in different altitudes in dry-hot valleys of Western Sichuan were investigated. There was not any significant difference fould between Songpan and Jiuzhaigou, except the average branch diameter. Principal components analysis (PCA) was applied to analyze the 15 traits of Amygdalus tangutica. According to more than 85% of the cumulative variance proportion, the results proposed comprehensive assessments of these trees. It would provide a basis for the superior variety selection of Amygdalus tangutica in Sichuan province.
