| 摘 要： | 研究结果表明, 栽培条件下2年生细叶百合实生苗中不抽茎、抽茎不开花和开花的比例分别为: 38.79% , 47.66%和13.55%。3年生和4年生细叶百合全部开花, 且开花比例随栽培年龄增加而增大。花粉和胚珠比为: 栽培164.9～175.2; 野生284.4～315.6, 其繁育系统为兼性自交。全光栽培下, 相对生殖成功率随植株年龄增加而增大, 2年生植株, 全光条件的相对生殖成功率是林下的7.5倍; 野生与全光下的相对生殖成功率相差无几。在开花前5 d其柱头即有可授性, 花前1 d授粉的结实率最高。细叶百合无多父本效应, 单一父本结实率和种子产量反而较高。人工同株异花、自花授粉坐果率为自然传粉坐果率的1 /2左右, 毛百合及松叶百合的花粉对其生殖有很强的干扰作用。

| Abstract: | The research showed that the satus rate of 2nd-year Lilium pumilum with stooling and without stooling are respectively 47.66% and 38.79%, and the blooming rate for 2nd-year cultivated plants is 13.55% in term of cultivated condition. All the plants of 3rd-year and 4th-year L.pumilum can bloom, but the flower quantity has a positive correlation with the age of plants. The ratio of pollen to ovule is 164.9-175.2 for cultivated plant, and 284.4-315.6 for wild plant, so the breeding system is facultative selfing. In full sun, relatively reproductive rate of the cultivated plants has positive relation with the age of the plant. For the 2nd-year plants, relatively reproductive rate of the plants with the condition of full sunlight is 7.5 tines as that which grow under forest. Wild L. pumilum has the same relatively reproductive rate as the cultivated 2nd-year L. pumilum. which grows in full sunlight. It is discovered that the pollination acts on the stigmata 5 days before L. pumilum flower. The plants pollinated 1 day before flower bear luxuriantly. L. pumilum has no multi-parent effect, and the setting percentage and the seed yield for single parent is higher than that for multi-parent. The fruit-set rate of the plants with natural pollination is about 2 times of that with illegitimate pollination and self-pollination. The pollen which comes from L. daurucum and L.cernum heavily affects the natural reproduction of L. pumilum. |
