基于AHP观赏海棠切枝观果品种评价与筛选

The Evaluation and Selection of the Branch-cutting Ornamental Fruit Varieties of Ornamental Crabapple Based on AHP

为了筛选出观赏海棠果实观赏价值高和应用于切枝观果的材料,以67个观赏海棠品种为供试材料,运用层次分析法(AHP)构建了切枝观果综合评价体系。以观赏海棠切枝观果品种筛选的综合评价作为目标层,以果枝观赏性状、果实性状、果实观赏时期和观赏时间等3方面因素作为准则层,将果量、枝条造型、可采切枝长度、果色、果实形状、果实大小、果萼、果梗长、最佳观赏月份和果实观赏期等10个指标作为指标层评价因子进行综合评价。结果表明,在准则层中,果枝观赏效果所占权重较高;在指标层中,果色所占权重值最大,其次是果实观赏期和果量。参评观赏海棠品种中,‘饴糖’(‘Sugar Tyme’)、‘唐纳德·怀曼’(‘Donald Wyman’)、‘红宝石’(‘Red Jewel’)、‘亚当斯’(‘Adams’)、‘大卫’(‘David’)、‘草莓果冻’(‘Strawberry Parfait’)、‘雪球’(‘Snow drift’)等7个品种综合得分均≥4.0,是秋冬季良好的室内瓶插素材和优良的观果品种。

Analytic hierarchy process(AHP)was used to establish an assessment standard for branch-cutting varieties of 67 ornamental crabapples to select the proper species with the highest ornamental value.The target level was the comprehensive assessment for branch-cutting varieties of ornamental crabapple fruit.The criterion level was consisted of fruit branch ornamental effect,fruit character and period and days of fruit viewing.The index level included fruit setting,branch modeling,branch length for cutting,fruit color,fruit shape,fruit size,calyx,length of stalk,the best viewing time and fruit viewing period.Results indicated that fruit branch ornamental effect was more important at the criterion level,and the fruit color was more important at the index level,followed by fruit viewing period and fruit setting.7 ornamental crabapple varieties were good for flower arrangement and fruit appreciation with the score above 4.0.
