基于层次分析法的切花多头菊品质性状评价

为筛选出适合浙江地区种植的切花多头菊品种,根据切花菊评价标准和菊花DUS测试技术,对11个品种的12个田间性状进行观察测量和评分,利用专家咨询法和层次分析法建立评价体系。结果表明,应用层次分析法对标准层4个因素进行权重排序,花部特征的权重值最大,其他依次为整体感、光感周期和瓶插期及叶部特征,表明花部特征对于切花菊的综合评价影响最大,而叶部特征对其影响最小。对目标层的12个影响因子的权重进行赋值,其中花色、花型、花朵数和株高相对于其他性状的权重大,说明其对切花多头菊品质影响最大。最终筛选出4个优良品种,分别为‘罗西梅红’、‘罗西黄’、‘绿橄榄’、‘斯奈’。

Spray Cut Chrysanthemum: Evaluation of Quality Characters by AHP

The purpose is to select the suitable spray cut chrysanthemum varieties for planting in Zhejiang Province. According to the evaluation standard of cut chrysanthemum and DUS test technology, 12 field characters of 11 varieties were observed, measured and scored, and the evaluation system was established by expert consultation and the analytic hierarchy process (AHP). The results showed that the weight of four factors in the standard layer was ranked by AHP, and the weight value of flower feature was the highest, followed by the whole sense, light sense period, bottle insertion period and leaf feature. It showed that the characteristics of flower parts had the greatest influence on the comprehensive evaluation of cut flower chrysanthemums, while the characteristics of leaf parts had the least influence. The weight of 12 influencing factors was assigned by AHP, among which the weight of flower color, flower type, flower number and plant height was significant compared with other characters, indicating that they had the greatest impact on spray cut chrysanthemum. Finally, 4 good varieties were screened out, which were ‘Rossi Splendid’, ‘Rossi Sunny’, ‘Olive’, and ‘Snazzy’.
