摘要
【目的】建立铁线莲属Clematis栽培品种观赏性综合评价体系,为合理引进和应用铁线莲栽培品种资源提供理论依据。【方法】对20个铁线莲品种植株、叶、花、果性状的生长物候期进行调查,采用层次分析和灰色关联度分析法,评价其观赏性。【结果】(1)20个铁线莲品种可分为常绿和落叶2种生态型。(2)植株在杭州地区的萌芽期、抽枝展叶期多集中在2月上中旬至3月中下旬,花期多处于4—6月(‘蓝焰’‘Bagatelle’和‘蓝光’‘Blue Light’等7个品种在7—12月可以2次开花)。(3)萼片多为紫红色系、蓝紫色系或具2种颜色以上的复色系。【结论】经观赏性评价和聚类分析,‘蓝焰’和‘茱莉亚夫人’‘Madame Julia Correvon’的综合评价得分最高(Ⅰ级),Ⅱ级含‘羞嗒嗒’‘Innocent Blush’等4个品种,Ⅲ级包括‘乌托邦’‘Utopia’在内的3个品种,Ⅳ级包括‘朱卡’‘Julka’在内的9个品种,Ⅴ级含‘蓝光’和‘丹尼尔德隆达’‘Danniel Deronda’。Ⅰ和Ⅱ级的6个品种可优先在杭州地区推广应用。表12参17。
[Objective] The objective is to establish a comprehensive evaluation system for ornamental quality of Clematis cultivars, so as to provide a theoretical basis for the rational introduction and utilization of Clematis cultivars. [Method] The growth phenological periods of plant, leaf, flower and fruit traits of 20 Clematis varieties were investigated. The ornamental value was evaluated using analytic hierarchy process and grey correlation analysis. [Result](1) The 20 Clematis cultivars could be divided into 2 ecotypes: evergreen and deciduous.(2)The budding stage, branching and leaf spreading stage of plants in Hangzhou were mostly in early and mid-February to mid-March and late March. The flowering period was usually from April to June, and 7cultivars including ‘Bagatelle’ and ‘Blue Light’ could bloom twice from July to December.(3) Sepals were mostly purplish red, blue purple or polychromatic with more than 2 colors. [Conclusion] Through ornamental evaluation and cluster analysis, ‘Bagatelle’and ‘Madame Julia Correvon’ have the highest comprehensive evaluation scores(Grade Ⅰ). Grade Ⅱ includes 4 cultivars such as ‘Innocent Blush’. GradeⅢ contains 3 cultivars including ‘Utopia’, and Grade Ⅳ contains 9 cultivars including ‘Julka’ and GradeⅤ includes ‘Blue Light’ and ‘Daniel Deronda’. 6 varieties of Grade Ⅰ and Ⅱ can be preferentially popularized and applied in Hangzhou.
