Variation and Correlation Analysis of Cone Traits and Seed Characteristics among Different Families of Pinus taiwanensis
摘要
Abstract
Taking 35 families of Pinus taiwanensis as the research objects,measured their cone traits and seed characteristic indicators,and analyzed the variability and interrelationships of these indica-tors using methods such as correlation analysis,stepwise regression analysis,and cluster analysis.The results showed that the variation coefficient range of the indicators was between 4.73％and 21.67％.There were extremely significant differences among the indicators of different Pinus taiwan-ensis families.The longitudinal diameter,transverse diameter,single fruit fresh weight,and size of the cones had extremely significant effects on the thousand-seed weight of the seeds,with the trans-verse diameter of the cones being the most important determinant factor.The cones of the 35 families were divided into three types by cluster analysis,and the first type,which included families 1,14,15 and 33,could be considered as excellent candidate families for seed collection in Huangshan.关键词
