Abstract:: Lilium brownie var.viridulum from Wanzai was used as test material.The effect of stigma receptivity，hybrid index(OCI) and pollination way on setting seeds was studied，and pollen tube extension was observed by fluorescence. The results showed that Lilium brownie var.viridulum could be pollinated in a long period of 10 days from the day before that flowering to 10 days later，specially during 4-6 days after blooming.The pollen germinating rate was the highest during 1-3 days after blooming.Pollen-ovule(P/O) was from 3 673 to 4 670 and OCI was 5.Due to the breeding system of the obligate outcrossing,the pollination medium was necessary for Lilium brownie var.viridulum to lead to the successful pollination.Pollens from the same flowers were accepted and grew seeds.Pollination by cutting stigma contributed to the reproduction.
