2010—2012年对垂枝栗1号、垂枝栗2号2个垂枝型板栗品种的生物学特性进行了评价。结果表明,垂枝栗2号在结果枝数、结果枝比率、单位面积产量等方面表现优于垂枝栗1号,其果形、果皮颜色、茸毛分布、果肉颜色、果肉质地与垂枝栗1号基本一致,综合品质优于垂枝栗1号。2个品种树势中庸、树姿披垂、树干逆时针旋曲盘升,其中垂枝栗1号左旋程度明显高于垂枝栗2号。垂枝栗2号为生产和绿化兼用种质资源;垂枝栗1号更宜作观赏资源。
The biological characteristics of two weeping chestnut varieties, Weijianli 1 and Weijianli 2, from 2010 to 2012 were evaluated. The results showed that weeping chestnut No. 2 had better performance than that of weeping chestnut No. 1 in terms of the number of branches, the ratio of branches and the yield per unit area. The fruit shape, the color of peel, the distribution of furry hair, the color of flesh, No. 1 basically the same, the overall quality is better than weeping chestnut No. 1. Two varieties of trees moderate, tree-like drape, trunks anti-clockwise curly plate rose, which weeping chestnut No. 1 left significantly higher than the weeping chestnut No. 2. Weeping chestnut No. 2 for the production and use of both green germplasm resources; weeping chestnut No. 1 is more suitable for viewing resources.
