摘要:目的
构建文冠果Xanthoceras sorbifolia不同类型的评价指标体系, 为类型评价、实现分类经营提供依据。
方法在掌握文冠果生物学特性及类型划分的基础上, 应用层次分析法构建优良类型综合评价指标体系。
结果综合评价指标体系由目标层、控制层和指标层组成。目标层由生长性状、种子及果实性状、产量性状、产油性状、物候期性状组成。指标层由19个具体指标组成。应用层次分析法、特尔斐法、指数综合评价法确定了各评价指标的权重和评价方法。利用该指标体系对内蒙古赤峰地区文冠果各类型进行评价的结果显示:花朵类型中, 单瓣白花型和单瓣红花型的得分较高, 分别为3.96和2.75;果实类型中, 大球果型得分最高(3.98), 其次是圆柱果型(3.67)、三棱果型(3.50), 这3类为入选的丰产高油优良类型。
结论所建立的评价指标体系能满足以油用为目的的文冠果优良类型选择要求。
Abstract:ObjectiveTo construct a comprehensive evaluation index system of Xanthoceras sorbifolia germplasm, and provide the basis for type evaluation and classified management.
MethodBased on biological characteristics and type classification of X.sorbifolia, a comprehensive evaluation index system was established by analytic hierarchy process.
ResultThe comprehensive evaluation index system was composed of three layers including a target layer, a control layer and an index layer.The target layer included growth, seed and fruit, seed production, oil production and phenophase characteristics.The index layer was composed of 19 indices.The weighted values of each index and evaluation method were determined by analytic hierarchy process, Delphi and index comprehensive evaluation methods.X.sorbifolia types in Chifeng, Nei monggol were evaluated using the comprehensive evaluation index system.Among different flower types, the scores of simple white flower (3.96) and simple red flower (2.75) were the highest.Among different fruit types, the score of big spherical fruit was the highest (3.98), followed with cylindrical fruit (3.67), and triquetrous fruit (3.50), and these three fruit types were considered as superior types with high production and high oil contents.
ConclusionThe established evaluation index system can enable the selection of X.sorbifolia types for the purpose of oil production.
