摘要
该文把数量分类方法应用于菊花７８个品种的分类．选取了菊花（Ｄｅｎｄｒａｎｔｈｅｍａ×ｇｒａｎｄｉ－ｆｌｏｒｕｍ）３８个性状，对７８个菊花品种（秋菊中的大菊）进行数量分类，Ｑ型聚类分析的结果表明：花瓣形状应作为菊花品种分类的第一级标准，花型应作为第二级标准．７８个菊花品种分成了平瓣类、匙瓣类、管瓣类、桂瓣类、畸瓣类５大类，共２７个花型．并对毛刺品种、剪绒品种在菊花品种分类系统中的位置做了讨论．抽取１０个菊花品种进行鉴定，各个品种全部鉴定为它们所应属的花型．
This paper deals with the numerical classification of the cultivars of chrysanthe-mum(Dendranthema grandiflorum).38 characters were selected,78 cultivars of chrysanthe-mum(Large-flowered autumn chrysanthemums)were subjected to the numerical classification.Results obtained through Q cluster analysis show that the first criterion of classification of culti-vars of chrysanthemum is the shape of petals.The second is the flower type.7 8 cultivare ofchrysanthemum are divided into five groups:flat-petalled group, spatulate petalled group, quill-petalled group,anemone-petalled group,abnormal-petalled group,together with their 25 flowertypes.The position of cultivars with burr and fine hairs in the classification system of chrysan-themum was discussed.Ten samples were taken from cultivars of chrysanthemum.The result ofidentification showed that all cultivars were identified into the types they should belong to.
