The Research on Samara Characteristics of Maple Germplasm Resources

Seeking for the relativeness and evolvement trend of maple,seven samaras characteristics of 68 maple germplasms(including twenty-seven species,two varieties and two cultivars) were made the principal component analysis using SAS8.0 statistical software.The results showed the cumulative was up to 83.9% of the first three principal components which represented integrated factor of size,angle,yield respectively.In addition,according to clustering analysis of seven samaras characteristics,relativeness of maple was discussed furtherly,which provided important information for the research of maple germplasm resources.
