【摘要】 首次应用形态系统数值分类法聚类分析，取桑属的大量形态性状经加权量化处理，采用计算机统计分析，对桑属12个种、2个变种及20个栽培品种进行了系统发育、进化趋势及亲缘关系的研究，探讨了形态系统数值分类法在桑树系统学研究方面的应用前景。更多还原

【Abstract】 Morphology-systematic-numerical taxonomy is adopted for the first time for classfication of mulberry. Systematic development, evolutionary tendency and relation of 12 species,2 varieties and 20 cultivars are analysed with computer. The application of morphology-systematic-numerical taxonomy in phylogenetic classfication of mulberry in the future was predicted.更多还原
