| 深入研究20个萱草品种的物候期、形态特征以及生长适应性，对其进行系统观测，为筛选出适宜在杨凌地区栽植的萱草品种并为大量引进萱草提供引种依据。研究通过实地调查、文献查阅、征询专家意见等确定了株高、冠幅、叶片数等15个评价因子，建立了萱草综合评价体系，应用层次分析法对20个萱草品种进行了评价。结果表明：引进品种均能正常生长发育，不同萱草品种物候期存在差异，萌芽期集中在3月上旬，展叶期在3月中上旬，花期在5月到8月，11月中上旬进入枯黄期。各品种在形态特征以及生长适应性方面均存在不同程度的差异。层次分析法结果表明，抗病虫害能力、群体花期长短和耐热性是萱草综合评价的首要考虑因素，生长势、花期早晚、单莛花朵数、花色等占较大比重。依据各品种综合评价得分，将20个萱草品种划分为3个等级。筛选出‘波斯集市’、‘艾米丽’和‘女人心’3个Ⅰ级品种，适宜在杨凌大面积推广种植，‘原谅我’等9个品种整体表现良好，有一定引种价值，可以进行推广与应用，‘拇指’等8个品种综合表现较差，不适宜在杨凌推广应用。 |
| 英文摘要: |
| In recent years, Hemerocallis fulva has been widely introduced and cultivated across China due to its potential for garden use. However, it has not previously been introduced in the Yangling region. To screen out daylily varieties suitable for cultivation in Yangling and to support the large-scale introduction of Hemerocallis fulva, 20 varieties were systematically evaluated in terms of phenology, morphological traits, and growth adaptability. Fifteen evaluation indicators, including plant height, crown width, and number of leaves, were selected based on field observations, a literature review, and expert consultation. A comprehensive evaluation system was established, and the Analytic Hierarchy Process (AHP) was applied to assess 20 Hemerocallis fulva varieties.The results showed that all introduced varieties were able to grow and develop normally. However, variations were observed in phenological stages: budding occurred in early March, leaf expansion occurred in mid-March, flowering occurred from May to August, and leaf yellowing occurred in early November. Significant differences were also found in morphological traits and growth adaptability among the varieties. According to the AHP results, resistance to pests and diseases, the duration of the flowering period, and heat tolerance were the most critical factors in the comprehensive evaluation. Additional important factors included growth vigor, flowering time, number of flowers per stalk, and flower color.Based on their comprehensive evaluation scores, the 20 Hemerocallis fulva varieties were classified into three performance categories. In conclusion, among the tested varieties, ‘Persian Bazaar,’ ‘Miss Amelia,’ and ‘Woman’s Heart’ (Grade I) demonstrated superior performance and are suitable for large-scale cultivation in Yangling. ‘Pardon Me’ and nine other varieties showed good overall performance and have potential for selective introduction and promotion. In contrast, ‘Siloam Tom Thumb’ and eight other varieties exhibited poor performance and are not recommended for cultivation in this region. |
