摘要
在详细野外调查基础上,利用形态比较学方法,对河南垂丝海棠品种进行分类研究。共记载33个品种,根据品种分类原则和垂丝海棠品种演化规律,确定花瓣数目、果实形状为划分品种群的主要依据,花冠直径、开花时幼叶颜色、刺状枝的有无、花梗是否下垂、花香有无、花柱颜色、花柱与雄蕊的高度差异、花序下嫩梢的长度等性状作为品种群划分品种的主要依据。33个品种被分为3个品种群,其中单瓣海棠品种群6个品种,圆果海棠品种群17个品种,梨果海棠品种群10个品种。3个品种群的演化途径为单瓣海棠品种群→圆果海棠品种群→梨果海棠品种群。
Cultivar investigation and classification of Malus halliana Koehne in Henan Province were cartied out on the basis of morphology. Thirty three cuhivars were recorded. According to the cultivar classification principles and the regulations of cultivars evaluation, the number of flower petal, fruit shape were taken as the main basis for group classification, and the characters of flower diameter, color of young leaf, shoot thorn, pedicel droop, flower fragrantee, pistil color, difference in pistil height and stamen height, the length of burgeon next to anthotaxy etc. were taken as the main basis for cultivar classification. All cultivars were devided into 3 groups, including 6 cultivars in single annulus group, 17 in round fruit group, 10 in pear shape fruit group. The evolving pattern of the three groups is single annulus group to round fruit group, to pear shape fruit group.
