- 摘要:
- 以野生细叶百合为试材,通过田间观察和人工授粉试验,对细叶百合的开花生物学和繁育系统等生殖生态方面进行了比较全面系统的研究,以期为其在迁地保护、繁殖栽培、杂交育种等方面的合理开发利用提供理论依据。结果表明:细叶百合的花期为6月初至6月中,群体花期约15 d,单花花期约5~7 d,花粉在整个花期均存在活力,且能在4℃条件下保存40 d左右,柱头在花开1~3 d可授性最强;花粉-胚珠比(P/O)介于3 051~12 857,杂交指数(OCI)为5,因而认为细叶百合的繁育系统为异交类型;人工授粉和自然结实率均明显高于自花和同株异花的结实率,而且人工异株异花授粉结实率又明显高于自然结实率,说明存在传粉限制,需要传粉媒介为其传粉;实地观察显示细叶百合有昆虫访花,为虫媒传粉。
- Abstract:
- Taking wild Lilium pumilum as test material,through the field observation and artificial pollination test method,a comprehensive system of reproductive ecology aspects on blossom biology and breeding system of wild Lilium pumilum were researched,to provide theoretical basis for reasonable development and utilization in exsitu conservation,propagation cultivation,cross breeding,and so on.The results showed that L.pumilum bloom from early June to mid June,group flowering about 15 d,single flowers flowering about 5~7 d,pollen in the flowering stage had vitality,and could be stored at 4℃ for 40 d,receptivity of stigma was the best after flowering 1~3 d.Pollen-ovule ratio (P/O) between 3 051~12 857,hybrid index (OCI) was 5,breed system of L.pumilum was outcross type.Artificial pollination and natural seed setting rate were significantly higher than self pollination and geitonogamy setting rate,and artificial different strains cross-pollination seed setting rate was obviously higher than that of the natural seed setting rate,indicating there existed pollination restrictions,need pollination media for their pollination.Field observation showed that L.pumilum had insect visit flowers,belonged to insect pollination.
