摘要
为了科学评价苦苣苔科(Gesneriaceae)植物的观赏性状,以苦苣苔科的35种植物为材料,运用层次分析法构建苦苣苔科植物的综合评价体系,对花、叶、株型特征、栽培表现等4个方面的15项具体评价指标进行打分。结果表明,35种苦苣苔科植物可划分为4个等级,划分为Ⅰ级的苦苣苔科植物综合得分最高,观赏价值亦最高,此类植物有5个种归为4个属,分别是喜荫花属喜荫花、花脸苣苔属艳斑苣苔、长筒花属长筒花、报春苣苔属的异色报春苣苔和都安报春苣苔。通过聚类分析可将35种苦苣苔科植物按观赏性状分为5类,其中划分为第1类的有5种,这与层次分析法评价出的Ⅰ级种类完全一致。该5种在育种和生产上应具有良好的前景,可为中国培育具有自主知识产权的高观赏价值品种奠定基础,促进中国苦苣苔园艺产业的发展壮大。
To scientifically evaluate the ornamental traits of Gesneriaceae plants,35 species of Gesneriaceae plants were selected to establish a comprehensive evaluation system for the ornamental traits of the Gesneriaceae plants by employing the Analytic Hierarchy Process(AHP).In this system 15 specific indicators were selected for assessment across four dimensions,i.e.floral characteristics,foliar features,plant architecture,and cultivation performance.The results showed that all the 35 species could be classified into four grades.The species in Grade I achieved the highest composite scores and ornamental value,comprising five species from four genera:Episcia cupreatasri,Kohleria bogotensis,Achimenes erecta,Primulina heterochroa,Primulina duanensis.Cluster analysis categorized the 35 species into five groups based on ornamental traits,with Group 1 containing the same five species identified as Grade I through AHP.This consistency confirms the exceptional ornamental potential of these species,indicating their significant prospects for breeding and horticultural production.These findings provide a foundation for developing proprietary ornamental cultivars with high aesthetic value in China,thereby advancing the horticultural industry of Gesneriaceae.
