摘要
本文就枇杷叶背茸毛是否脱落和花期能否作为分类标准进行了讨论。同时,提出了一个以枇杷属植物雄蕊、柱头和叶片大小等形态学性状为主要依据,结合分子标记结果而制定的枇杷属植物分类系统。分为3个类群:①少雄蕊、小叶片类群;②多雄蕊、多柱头、大叶片类群;③多雄蕊、少柱头、中叶片类群。其中,第3个类群又分为4个亚类。
The value of blossom period and whether the floss of leaf back falling off or not in the classification of loquat was discussed. A new classification system was presented based on the morphology of pistil, stigma and size of leaf in combination with the results from DNA marker study. The new classification system divides the Eriobotrya species into three groups: (1) small leaves, fewer stamens (〈20). (2) more stamens (≥20), more stigmas (≥5), big leaves. (3) more stamens (≥20), fewer stigmas (〈5), mid-sized leaves. Group 3 can be further divided into four subgroups.
