基于层次分析法的盆栽东方百合品种综合评价体系构建

【目的】建立盆栽东方百合品种综合评价体系,筛选出适合广西地区规模化设施栽培的优良百合品种。【方法】观测统计12个盆栽东方百合品种的20个植物学性状指标,应用层次分析法从花性状、茎叶性状和生长适应性3个方面构建盆栽东方百合品种的综合评价体系。【结果】通过对花性状、茎叶性状和生长适应性赋权,确定评价20个性状指标的权重值,其中叶烧情况、成花率、花径、落叶情况和株型紧凑度的总排序权重所占比重较大,分别为0.1429、0.1372、0.1139、0.0714和0.0677;根据品种综合评价得分,将12个东方百合品种划分为优秀、优良、一般和较差4个等级,其中,Entertainer、Starlight express、Souvenir、Bahamas和Pink champion 5个品种综合性状表现优良,适合小规模生产;Fortune和After eight综合性状表现差,可淘汰。【结论】东方百合品种Entertainer、Starlight express、Souvenir、Bahamas和Pink champion具有花朵硕大、花色艳丽、花期长、株型紧凑和适应性强等优点,可作为广西地区设施盆栽百合品种引进推广。

Establishing comprehensive evaluation system for potted Oriental lily cultivars based on analytic hierarchy process

Objective]A comprehensive evaluation system for potted Oriental lily cultivars was established to screen the proper cultivars for scale planting in Guangxi.Method]Twenty botanical characters for twelve potted oriental lily cultivars were observed and recorded. A comprehensive evaluation system for potted Oriental lily cultivars was established using analytic hierarchy process from three perspectives of floral traits , leaf traits and growth adaptability. Result]Through weight determing for floral traits,leaf traits and growth adaptability weights of 20 traits factors was calculated. Among all the factors, the weights of leaf burn (0.1429),flower formation rate (0.1372),flower diameter (0.1139),leaf abscission (0.0714) and plant type compact degree(0.0677) were high compared to others. According to the scores of comprehensive evaluation,twelve cultivars were divided into four grades:excellent,good,general,and poor. Five cultivars (Entertainer, Starlight express, Souvenir, Bahamas and Pink champion) with superior comprehensive traits could be applied to small scale planting. Fortune and After eight which were with poor comprehensive traits were eliminated. Conclusion]Entertainer, Starlight express, Souvenir, Bahamas and Pink champion, which enjoy good traits of large flower, bright color, long florescence, compact plant type and strong adaptability, are suitable for introduction as potted lily cultivars in Guangxi.
