摘要
为了解不同种源地葛萝槭表型变异程度及变异规律,对5个种源地69个单株葛萝槭的果实和种子表型性状进行分析。结果表明:不同种源地葛萝槭果实和种子表型性状存在不同程度的变异,变异系数范围为1.76%~10.94%,种群间表型性状的差异性较为显著;利用系统聚类可将5个种源地葛萝槭分为3类,葛萝槭种群间具有明显的地理变异规律。
Analysis the phenotypic traits of Acer grosseri fruits and seeds from 69 families in five provenances,in order to reveal phenotypic variation and variation patterns of Acer grosseri from different provenances.The results indicated that different extent of variation in phenotypic traits of Acer grosseri from different provenances,coefficient of variaton ranged from 1.76%to 10.94%,there were significant differences among populations in phenotypic traits.Five provenances of Acer grosseri were divided into three groups by using hierarchical clustering,obvious laws of geographic variation among populations of Acer grosseri.
