| Abstract: | Seed phenotypic characteristics for 130 families in 7 populations of Sophora japonica Linn including seed length,seed width,ratio of seed width and length,seed surface area,seed volume and 1000-seed weight were studied in order to reveal phenotypic variation and variation patterns in different districts.Phenotypic variation among and within populations was analyzed by using variance analysis and correlation analysis.Results showed that different extent of variation exited in phenotypic characteristics of se... |
