摘要:
为了研究黄毛草莓的开花生物学特性，观测黄毛草莓的散粉规律和繁育系统，并以不同时期的花蕾为试材，用不同方法测定花粉的萌发率和柱头可授性。结果表明：黄毛草莓的单朵花期为2 d，散粉时间为每天9∶30～17∶00，在12∶00～14∶00达到顶峰。黄毛草莓的花粉在开花盛期活力最大，其它时期均较低或没有活力。柱头可授性在开花初期和盛花中期达到顶峰，持续到末花期仍具有一定的可授性。
Abstract:
In order to study the biological characteristics of flowering of Fragaria nilgerrensi,pollen-shedding rule and breeding system of Fragaria nilgerrensis were observed.Buds of different periods were used as test materials to determine the pollen germination rate and stigma receptivity with different methods.The result showed that the single flower season of Fragaria nilgerrensis lasted for 2 days,9∶30～17∶00 each day was considered to be pollen-releasing period and it peaked from 12∶00～14∶00.The pollen viability reached the top during the flowering stage,but in other periods were lower or were not viable.Stigma receptivity peaked at early flowering period and mid-full bloom stage.It had a certain degree of receptivity till the end of flowering season.
