Abstract:

Based on the principal component analysis and the cluster analysis of phenological observation data from 70 meteorological observation stations for 8 years (1994—2002), which were located in all the distribution regions of Melia azedarach in China, the distribution regions of Melia azedarach in Chinese were divided into 11 phenological areas. It will provide a scientific basis for seedling rational allocation and germplasm resources conversation for Melia azedarach; and the phonological isophene map will be a guidance for agriculture and forestry production in the most parts of southern China.

Key words: Melia azedarach, phenological, germplasm resources, principal component analysis, cluster analysis
