| 中文摘要: |
| 取普通油茶的花为试材，对油茶单花开放情况进行观察，并研究了不同条件对油茶花粉萌发率
的影响。结果表明：所选油茶单株的单花开放时间为5~16 d，且单花寿命受天气影响；花粉萌发的适宜培养
基为10% 蔗糖+0.005% 硼酸+1% 琼脂；不同的采花时间花粉萌发率差异较大，而不同的花朵保鲜方式花
粉萌发率差异不大；各种干燥处理的花粉萌发率均高于对照，适度的加热处理有助于花粉萌发；不同储藏条
件下，花粉生活力差异较大，-20℃冷冻条件下储藏效果最佳，而室温干燥箱储藏的花粉萌发率下降迅速，
至150 d 全部失活，-4℃冷藏条件下储藏的花粉萌发率为39.43%，-20℃冷冻条件下储藏的花粉萌发率仍在
55% 以上。 |
| 英文摘要: |
| Taking flowers of Camellia oleifera as materials，the opening process of single flower and the pollen
germination rate in different conditions were studied in this paper. The opening time of single flower lasted 5-16
days，the lifespan would be affected by weather. The suitable medium components for pollen germination were
10% sucrose，0.005% boric acid，and 1% agar. Florescence rather than flower preservation mode had influence on
pollen germination rate. The germination rates of pollen after several drying treatments were all higher than that of
control，and moderate heat treatment was conducive to pollen germination. In different storage conditions，the pollen
vitalities were significantly different，the best was storage at -20℃. At room temperature，the pollen germination rate
decreased rapidly，the pollen was inactive after 150 days. The germination rates were 39.43% and above 55%，at 4℃
and -20℃ storage，respectively. |
