A Comparative Study of Fruit and Seed Characteristics of Plus Trees of Idesia polycarpa Maxim.var.vestita Diels
摘要
Abstract
The plus trees of Idesia polycarpa Maxim.var.vestita Diels(IPM) variety were collected from Guangyuan region.Phenotype diversity of fruit and seed was analyzed by using the methods of ANOVA,Multiple comparison,Correlation analysis,Cluster analysis etc.The results showed that IPM had great differences among different plus trees except the seed shape index.The average coefficient of variation of the 10% kernel weight was the largest(24.36%),and that of the seed weight was the second largest(22.413%) and the fruit shape index had the lowest variation coefficient(4.17%).These indicated that the fruit shape was the most stable.Significant linear correlation was found between the fruit diameter and weight.So,the weight of fruit was predictable.The 19 plus trees of IPM investigated could be divided into two groups according to the cluster analysis.关键词
