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。
Acer tutcheri is one of important color-leaf and fruit ornamental trees in south China.The mor-phological character,geographic distribution and habitat of A.tutcheri is illustrated in brief.Six families has been regarded as the objects,and thousand-grain weight,germination rate,growth,and the scenic beauty has been car-ried out.The results showed that the different family has diverse thousand-grain weight,with an average of 31 .89 g.Seed germination rate is low,with an average of 1 6 .63%;Seedling growth rate of A.tutcheri is general,aver-age ground diameter and height of 1 year old seedling was 0.48cm and 1 8.60 cm,respectively.The scenic beauty of family 2 and 3 is higher.
