综合权重法评价不同菊花品种的扦插生根能力

Comprehensive Evaluation of Rooting Ability of Cuttings from Different Chrysanthemum Cultivars by Synthetical Weight Analysis

试验以AHP法和主成分法相结合的综合权重法对20个菊花栽培品种的7个生根相关形态性状进行综合评价分析,构建综合评价函数,依据综合法确定的权重计算综合评分,将20个品种的生根能力由强到弱分为3个等级,各等级分别包含6、9、5个品种,该方法能全面、客观、有效分析不同菊花品种的生根能力。

Seven morphological indexes related to rooting ability of cuttings from 20 chrysanthemum culti- vars were comprehensively evaluated using the method of synthetical weight analysis. The synthetical weights of the indexes were calculated by method of analytic hierarchy process （AHP） and principal components analysis. The comprehensive evaluation function was built up. Twenty cultivars were divided into three groups according to the scores of comprehensive evaluation of rooting ability,6 cultivars were included in the group with strong rooting ability,9 eultivars in the group with middle rooting ability, the remaining 5 cultivars were included in the group showing poor rooting ability. This analysis method developed here is a practical,objective and efficient way to analyze rooting abilities of cuttings from different chrysanthemum cultivars comprehensively.
