摘要
以引进的20个铁线莲品种为实验材料,研究其在山东烟台的环境适应性、观赏性和物候表现,并运用层次分析法(AHP)对其进行综合评价和筛选。结果表明:花色、花量和花径是其观赏性评价的最重要指标;生长势是影响其适应性的主要因子。根据评价结果,将引种的铁线莲划分为5个等级:Ⅰ级包括‘皇后’等3个品种,观赏性状优异,生长强健,非常适合在烟台地区进行栽培和园林应用;Ⅱ级包括‘伍斯特美女’等4个品种,观赏性状优秀,生长良好,适合在烟台地区生产应用;Ⅲ级为‘自行车岛’等6个品种,观赏性和适应性等均有不错的表现,具有一定的应用推广价值;Ⅳ级为‘天空’等5个品种,适应性与观赏价值综合评价较低;Ⅴ级为‘纪三井寺’和‘红星’2个品种,综合评价最低。
The adaptability,ornamental value and phenological performance of 20 Clematis species introduced to Yantai region were comprehensively evaluated and selected by using Analytic Hierarchy Process(AHP).The results showed that the color,quantity and diameter of flowers were the most important indexes of ornamental value.Growth potential was the main factor affecting the adaptability.According to the evaluation results,these Clematis species were classified into five grades.The 3 species including C.EMPRESS‘Evipo 011’were in gradeⅠ,which had excellent ornamental value and growth ability,perfectly suitable for cultivation and application in Yantai.The 4 species including C.‘Beauty of Worchester’were in gradeⅡ,which had good ornamental value and good growth ability,suitable for application in Yantai;C.‘Charissima’and other 5 species were in gradeⅢ,whose ornamental value and adaptability are quite good,therefore had certain value for introduction and application;The 5 species such as C.‘Tenku’were in gradeⅣ,whose comprehensive evaluation is relatively low;C.‘Kimiidera’and C.‘Red Star’belong to gradeⅤ,with the lowest comprehensive evaluation.
