Abstract

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.
