摘要:以鹅掌楸的冬芽为材料,提取DNA做模板,用14个引物对131个鹅掌楸样本进行RAPD分析,扩增出235个谱带,显示该属植物具有丰富的遗传多样性。结果表明:①中国鹅掌楸群体多态位点百分率为88.98%,北美鹅掌楸91.06%,杂种鹅掌楸89.98%。②中国鹅掌楸遗传变异分量在群体间占33.03%,群体内占66.97%;北美鹅掌楸分别为8.73%和91.27%;主要变异均存在于个体间。③聚类表征图表明杂种鹅掌楸与北美鹅掌楸的遗传距离较近。
Random amplified polymorphic DNA (RAPD) markers were used to estimate genetic diversity of Liriodendron. Fourteen primers generated 235 bands from 131 samples. It was indicated that Liriodendron has high genetic diversity. (1) The polymorphic bands percentage of L. chinense (Hemsl.) Sarg., L. tulipifera L. and hybrid clones ware 88.98 %, 91.06 % and 89.98 %, respectively. (2) The genetic variation was observed within populations. (3) Clustering data indicated that the hybrid clones is close to L. tulipifera L. in heredity. Basic data were provided for further studies on the genetic variation, selection and evaluation of Liriodendron.
