| 摘 要： | 首次利用来自6个国家的共计21个观赏品种,对其叶片形态多样性及形态指标进行了聚类分析。结果表明,观赏品种的叶形具有多样性,可分成9类;叶缘、叶基、裂刻数、叶色等形态指标差异较大。聚类分析发现, ‘金秋’(Aut．)和‘筒状银杏’(Tub．)均单独分为一类。对银杏观赏种质的多样性进行了探讨。 |

| Abstract: | The morphological diversity of leaf of twenty-one ginkgo cultivars from six countries was studied in this paper. There were nine types of leaf shape in ginkgo cultivars. Significant differences were also found in leaf margin, leaf base, the number of lobes, leaf color. Cultivars ' Aut.' and ' Tub. ' were significant different from other cultivars and were classified in the same group by means of cluster analysis. The diversity of ornamental germplasm was also discussed in this paper. |
| Keywords: | Ginkgo biloba Ornamental cultivar Leaf shape Leaf color |
