槭树科优良种质资源的评价与筛选

Evaluation and Selection of Aceraceae Germplasm Resources

[目的]筛选可在园林和城市景观中应用的槭树科优良种质资源。[方法]通过对24个槭树科植物17个方面的生物学特征观测与记录,并参考不同人群的美观度评价,以分值的方式统一量化打分,筛选优良种质资源。[结果]综合分值最高的前10个槭树科植物依次为鹅掌槭(45.5)、小鸡爪槭(43.8)、鸡爪槭(41.8)、秀丽槭(39.2)、长尾秀丽槭(39.2)、北美红枫(39.1)、紫果槭(38.8)、元宝槭(38.3)、橄榄槭(37.7)、锐角槭(37.3)。[结论]鹅掌槭、小鸡爪槭、鸡爪槭、秀丽槭、长尾秀丽槭、北美红枫、紫果槭、元宝槭、橄榄槭和锐角槭可优先为园林绿化中的优良种质。

Objective] The aim was to screen out excellent germplasm resources of Aceraceae plants which can be applied in urban landscape . [Method]17 indicators of biological traits were recorded in score mode,as well as aesthetic evaluation of different groups,excellent germplasm re-sources of Aceraceae plants were selected.[Result] Top ten highest comprehensive score of Aceraceae plants were Acer japonicum（45.5）,Acer palmatum（43.8）,Acer palmatum（41.8）,Acer elegantulum（39.2）,Acer elegantulum（39.2）,Acer rubrum（39.1）,Acer cordatum（38.8）, Acer truncatum（38.3）,Acer olivaceum（37.7）,Acer acutum（37.3）.[Conclusion] Acer japonicum,Acer palmatum,Acer palmatum,Acer elegantulum, Acer elegantulum,Acer rubrum,Acer cordatum,Acer truncatum,Acer olivaceum,Acer acutum can preferentially be selected for landscaping germ-plasm.
