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.
