| 摘 要： | 为了阐明鸡爪槭(Acer palmatum)翅果表型性状间的关系及其变异规律。从黄山学院校园内随机选择10棵生长健康的鸡爪槭单株,对10棵鸡爪槭的9个翅果表型性状进行调查分析。10棵鸡爪槭的9个翅果表型性状的遗传变异系数范围为5.68%~19.71%;9个翅果表型性状间相关系数的范围是-0.451 4~0.729 4,这表明翅果表型性状间关系密切复杂;基于9个翅果表型性状划分的4个组别间表型性状差异明显,可为营建不同用途的鸡爪槭提供基本材料。研究表明鸡爪槭翅果表型性状变异丰富,多层次的变异为不同选育目标奠定了基础。

Study on Samara Phenotypic Variation of Acer palmatum |

| Abstract: | 10 Acer palmatum plants were selected randomly in Huangshan University campus to analyse 9 samara phenotypic traits to study the phenotypic variation within and among single plant. The results showed that the genetic variation coefficients of 9 charac-ters were ranged from 5.68%-19.71%,the correlation coefficients from-0.451 4 to 0.729 4,which indicated that they had complicat-ed relationships with each other. Significant differences in phenotypic traits of four groups divided based on the traits were identi-fied,which provided basic information for accessions with different purposes. Phenotypic variation of Acer palmatum was rich and the variations provide information for the preliminary selection and breeding of seeds for different purposes. |
