摘要
2009年和2010年通过大田试验对收集保存的58个单头切花菊品种主要品质性状进行观察统计,并建立了单头切花菊综合评价体系。应用专家咨询法并结合其他观赏植物评价体系,筛选出13个对单头切花菊品质性状影响较大的因子。应用层次分析法对各影响因子的权重进行定量评价,其中花径对单头切花菊品质影响最大,其权重为0.113;花色和舌状花数次之,其权重均为0.106。对58个单头切花菊品种进行K-Means聚类分析的结果为:优等级品种14个,占24.14%;良等级品种24个,占41.38%;差等级品种20个,占34.48%。品种评价结果与实际生产经验相符,表明应用专家咨询法、层次分析法和K-Means聚类法建立的评价体系可以很好地对单头切花菊品种进行评价和分级。
Field experiments were conducted to observe and count ornamental factors of 58 varieties of standard cut chrysanthemum in 2009 and 2010.A synthetic assessing system was established by means of expert consultation,analytic hiberarchy process and K-Means cluster method.The factors affecting the quality of standard cut chrysanthemum were analyzed,and 13 factors were selected.The weight of the 13 factors was quantitatively evaluated by analytic hierarchy process.The flower diameter,flower color and ray flower number had the most important effect,and the weight were 0.113,0.106,0.106,respectively.58 varieties of standard cut chrysanthemum were then clustered into 3 grades by K-Means cluster method.There were 14 varieties graded excellent,24 graded moderate and 20 graded poor,and the occupancy were 24.14%,41.38%,34.48%,respectively.The evaluation result was consistent with production practice,and the system constructed by adopting expert consultation,analytic hiberarchy process and cluster method can be used to evaluate and classify standard cut chrysanthemum varieties.
