以陕西省秦岭山区繁殖生产的亚洲杂交系百合品种为材料，在4℃冷藏处理的基础上，解剖观察了不同处理切花种球的花芽分化进程，发现经40d处理后，多数品种都开始了花芽分化，而且，花芽分化的进程在品种间有着明显的差异。根据各品种的现蕾特点，大致可分为早蕾型、中蕾型和晚蕾型三种类型。在品种栽培和切花评价中，认为London、Mona、Pollyanna和ConnecticutKing是适应上海地区冬季大棚栽培的主要品种。
Based on the cold storage treatment at 4 ℃, the flower bud differentiation process of cut flower bulbs of different treatments was observed in the hybrids of Lilium hybrids in the Qinling Mountains in Shaanxi Province. It was found that most cultivars began flower buds after 40 days treatment Differentiation, and, flower bud differentiation process has obvious differences between varieties. According to the varieties of the characteristics of the bud, can be divided into the early Lei type, Lei type and late Lei type three types. In variety cultivation and cut flower evaluation, London, Mona, Pollyanna and Connecticut King are considered as the main varieties adapted to winter greenhouse cultivation in Shanghai.
