| 摘要: |
| 岭南槭（Acer tutcheri）是华南地区重要的彩叶和观果树种之一。文章简述了岭南槭生物学特性，并以其6个家系为试材，开展了种子千粒重、发芽率、生长情况和美景度等方面的研究。结果表明：不同家系种子千粒重差异显著，平均为31.89 g；种子发芽率较低，平均为16.63％；岭南槭苗期生长速度一般，1 a生苗木平均地径为0.48 cm，平均高为18.60 cm；2号家系和3号家系岭南槭的美景度较高。 |

| Abstract: |
| Acer tutcheri is one of important colorleaf and fruit ornamental trees in south China. The morphological character, geographic distribution and habitat of A. tutcheri is illustrated in brief. Six families has been regarded as the objects, and thousandgrain weight, germination rate, growth, and the scenic beauty has been carried out. The results showed that the different family has diverse thousandgrain weight, with an average of 31.89 g. Seed germination rate is low, with an average of 16.63%; Seedling growth rate of A. tutcheri is general, average ground diameter and height of 1 year old seedling was 0.48cm and 18.60 cm, respectively. The scenic beauty of family 2 and 3 is higher. |
