以万载龙牙百合为试材,研究了柱头可授性、杂交指数OCI、不同授粉方式对龙牙百合结实的影响,并对其授粉后花粉管伸长情况进行了荧光观察。结果表明:龙牙百合柱头可授期为开花前1d至开花第9天,共10d,可授期较长,柱头在开花4~6d可授性最强;花粉生活力在开花第1~3天最强;花粉-胚珠比(P/O)介于3 673~4 670,杂交指数(OCI)为5,繁育系统属于专性异交,存在传粉限制,需要传粉媒介为其传粉;自花授粉能结实,切柱授粉有助于结实。
The effects of stigma receptivity, cross index OCI and different pollination methods on the fruiting of Aralia elata were studied. The pollen tube elongation after the pollination was observed by fluorescence. The results showed that the stigma of Aralia elata could be granted from 1 day before flowering to 9 days after flowering for a total of 10 days, The pollen-ovule ratio (P / O) ranged from 3673 to 4670, and the hybridization index (OCI) was 5. Breeding systems were obligate outcrossing with pollination restrictions and pollinators were needed for pollination. Pollination can be strong, cut column pollination helps to strong.
