热带地区切花百合新品种引种观察与评价（英文）

Observation and Evaluation of New Lily Cutflower Varieties Introduced in Tropical Area

[目的]引种、筛选百合新品种,为热带地区选择种植综合性状较好的百合品种提供参考依据。[方法]对从国外引进的百合新品种＂白色表达＂、＂木门＂、＂阿克迪瓦＂、＂多纳托＂、＂星球战士＂和＂西安＂在海南冬季进行露地引种栽培试验,观察、比较参试品种的物候期、形态特征和切花品质,筛选适宜海南种植的百合新品种。[结果]6个百合品种的生育期差别很大,介于96~113 d,平均为105.3 d;生物学特征表现较大差异,＂阿克迪瓦＂和＂西安＂具有花大色艳、植株高且整齐、花头数多、花期长和生长势强等优点,其观赏价值和品种适应性明显优于其他品种。利用百合分数等级测评机制来评价这6个品种,按得分高低依次排列为：＂西安＂〉＂阿克迪瓦＂〉＂木门＂〉＂星球战士＂〉＂多纳托＂〉＂白色表达＂。[结论]＂阿克迪瓦＂和＂西安＂两个百合切花新品种综合性状表现良好,适合海南三亚热带地区扩大试验和示范种植。

[Objective] New lily varieties were introduced and selected to provide ref- erences for choosing lily varieties with the best comprehensive performance and most appropriate for tropical area. [Method] In winter, six lily cultivars including White Express, Concad＇or, Aktiva, Donato, Star Fighter and Serano were planted outdoors in Hainan. Phenophase, morphological traits and cut flower quality of the tested cultivars were observed and compared in order to choose varieties suitable for Hainan. [Result] Their growth period ranged from 96 to 113 d with the mean of 105.3 d. Six cultivars had obvious differences in biological characteristics and cut- flower quality. Compared with the other 4 cultivars, Aktiva and Serano were superior for their bright color and beautiful shape, height uniformity, long florescence and strong growing. According to the comprehensive evaluation system of lily variety, the sequence was Serano 〉 Aktiva 〉 Concad＇or 〉 Star Fighter 〉 Donato 〉 White Ex- press. [Conclusion] The two cultivars of Aktiva and Serano with good characters are selected for further research and extension in Sanya of Hainan.
