观赏用枫香优树选择与种质资源收集

目的]建立观赏用枫香选优标准,建立采穗圃、基因库,为选育观赏用枫香新品种提供依据。方法]采用枫香叶色亮丽度等8个因子进行分级评分的方法制定标准;釆用无性繁殖方法培育优树苗木,营建采穗圃和基因库。结果]建立观赏用枫香选优标准,选出观赏用枫香优树50株,建立采穗圃0.33 hm~2、基因库0.33 hm~2。结论]观赏用枫香选优标准具科学性、可操作性和实用性;采穗圃和基因库的建立为开发新品种奠定了基础。

Selection of Ornamental Use Liquidambar formosana and Collection of Germplasm Resources

Objective] The aim was to establish plus tree selection standard for ornamental use Liquidambar formosana, cutting orchard and gene bank, to provide basis for new variety breeding.Method] 8 factors were adopted to formulate evaluation standard;Asexual reproduction method was used to culture excellent seedling and built cutting orchard and gene bank. Result] The plus tree selection standard was estab-lished.50 plants of ornamental use Liquidambar formosana were selected, 0.33 hm2 cutting orchard and 0.33 hm2 gene bank was built.Con-clusion] Plus tree selection standard is scientific, operational and practical; cutting orchard and gene bank lays a foundation for development of new varieties .
