摘要
提出了在梅种之下设置11个品种群的梅花品种群分类新方案。该方案既与国际栽培植物命名法规接轨,又保留了原有"花卉品种二元分类"的优点。在提新方案的同时,还发现并论证了梅核之宽厚比(宽/厚)也是品种群分类的重要标志之一。这是核面蜂窝状点穴之外一项新发现的指标。此指标对远缘杂种起源之杏梅品种群和美人品种群而言,意义尤著。文中还剖析了它们在南梅北移等方面的发展优势。
The authors revised the classification system for mei cuhivars (2007), and a new system (2008) including 11 cultivar groups proposed. A key for classifying the 11 groups is published, and reasons of establishing these groups explained. The revised system is better than the old one in which only 3 cultivar groups included. Both of the two systems are in agreement with the rules of I. C. N. C. P ( International Code of Nomenclature for Cultivated Plants, 2004), but the revised one reserves and expresses more superiorities of "Dual Classification Method" for Chinese traditional flowers. Meanwhile, on the basis of considering dot grottoes on stone surface as key criterion in group classification, it has been found recently that breath/thickness ratio of the stone also important as another key critorion. Moreover, special importance of these two groups both originated from interspecific hybridization, viz. apricot mei group and meiren (blireiana mei) group in acclimatization and development is pointed out.
