摘　　要： 为了获得最适合淡黄花百合花粉离体保存的条件,以不同发育阶段的淡黄花百合花粉为试材,采用TTC法测定花粉萌发率,研究了4种贮藏温度对3个发育阶段淡黄花百合花粉生命力的影响。结果表明:取样当天测定开花第3天的花粉生命力最强,萌发率为91.97%;开花当天的花粉萌发率为73.63%;开放前2d的花粉萌发率为70.60%。在不同温度下离体保存后,随着贮藏时间的延长,所有花粉的萌发率在前4d迅速下降,4d后下降变缓。通过对比,开花前2d和开花当天的花粉贮藏在4℃的条件下其生命力保持较好,保存时间不超过8d为宜。 Pollen of Lilium sulphureum Baker was employed as experimental material to carry on studies on viability and storage condition.Pollen viability of 3 development periods and 4temperature conditions were studied,and the germination rate was tested by TTC in these experiments.The results showed that fresh pollen of different development period had different viability.The pollen germination rate after flowering three days was 91.97%,flowering day was73.63%,and two days before flowering was 70.60%.Pollen from undeveloped bud and new blooming bud had the longest shelf life after storage.Storage temperature had great effect on pollen viability.4℃ was favorable for keeping pollen viability,and-20℃took the second place,but the storage period should be within 8days.
