摘要:
 通过对松辽平原西部、豫西山地、冀北山地的文冠果树体形态特征调查进行类型划分，为种质资源收集保存和良种选育提供依据。根据性状稳定性和易识别性，确定花瓣单重、花色、果实形状为文冠果天然类型划分指标。从生物质能源树种角度，将文冠果划分为结实型和观花型。结实型包括单瓣白花型，根据果实形状将其进一步划分为小球果、大球果、扁球果、倒卵果、桃形果、三棱果、圆柱果7种类型。观花型包括单瓣红花型、重瓣紫红型、重瓣黄花型。单瓣白花型在各地区都是最主要的类型，分布比率均>95%。根据各果实类型经济性状选择出适合不同地区的优良类型：松辽平原西部WQ地区为大球果型、三棱果型、圆柱果型；松辽平原西部AQ地区为小球果型、大球果型、圆柱果型；豫西山地为大球果型、圆柱果型；冀北山地为小球果型、大球果型、扁球果型、圆柱果型。倒卵果、桃形果的子代苗期各性状均值偏小。大球果、三棱果、圆柱果的子代生长好于小球果和扁球果。各苗期性状在类型间差异显著，类型内单株间除地径外，其余性状差异极显著。
Abstract:
 In order to provide scientific basis for germplasm resource collection, an investigation was carried out on the Xanthoceras sorbifolia resource classification based on the morphological characteristics of the tree in the areas of western Songliao Plain, mountainous area of western Henan and mountainous area of northern Hebei. Based on the stability and legibility of the characters, indices such as double petals, single petals, flower color, and fruit shape were chosen for the classification. From the point of biomass energy tree, X. sorbifolia was divided into fruiting type and flowering type. Fruiting type included single white flower type. This type was classified into small spherical fruit type, big spherical fruit type, cylindrical fruit type, triquetrous fruit type, flat-sphere fruit type, peach fruit type and obovate fruit type. Flowering type included single red flower type, double purplish red flower type, and double yellow flower type. Distribution characteristics of each type were investigated in each distribution area. Single white flower type was widespread in all distribution areas, and the distribution rates were higher than 95%. Super types were selected according to economic traits of fruit types:big spherical fruit type, triquetrous fruit type and cylindrical fruit type were super types in WQ area of western Songliao Plain; small spherical fruit type, big spherical fruit type and cylindrical fruit type were super types in AQ area of western Songliao Plain; big spherical fruit type and cylindrical fruit type were super types in western Henan mountainous land; small spherical fruit type, big spherical fruit type, flat-sphere fruit type and cylindrical fruit type were super types in northern Hebei mountainous land. Seedling growth traits of obovate fruit type and peach fruit type were lower than other types, and the seedlings of big spherical fruit type, cylindrical fruit type and triquetrous fruit type grown better than small spherical fruit type and flat-sphere fruit type. Seedling growth traits were significantly different among different types. The differences of other traits were extremely significant among individuals except ground diameter.
