石榴品种分类研究

针对石榴品种分类现状，在前人研究的基础上，根据实地调查的结果，分析了石榴品种的形成途径及主要形态特征。遵循《国际栽培植物命名法规》与品种演化规律，对石榴品种分类依据进行了研究,提出石榴品种形成属于同一种系来源，并建立了品种群——品种系统，即按照花瓣将石榴品种分为4个品种群，同时认为花瓣、花色、结实性、果色、果实大小及果重是品种分类的主要依据，而籽粒软硬、萼筒形状、新叶颜色、茎剌有无等特征可作为次级分类特征。

Studies on Cultivar Classification of Punica granatum

On the basis of obtained data and field survey of cultivar classification of pomegranate,the ways of cultivar formation and main appearance characteristics were analyzed in this paper. In the light of International Horticulture Nomination Code and the regulation of cultivars evaluation,the cultivar classification was discussed. The results show that cultivar formation of pomegranate belongs to the same type of species. The cultivar group, cultivar systems were built up. According to the flower petal, cultivars were divided into 4 cultivar groups. The flower petal, flower color, fecundity, fruit color, fruit size and quantity were taken as the main basis of classification,and the characters of the seed soft or hard,shape of calyx tube,color of new leaf,caulis stab etc. can be taken as a second basis.
