甜菜花为两性花,在开花后的3～5小时内,分泌出略具芳香气味的三甲胺汁液。甜菜开花期一般可延续20～40天。花药成熟后纵向开裂,20～30分钟之内散粉完毕,6小时之后花药干枯脱落。花粉粒呈圆球状,当开花期遇到35℃以上的高温,花粉粒可变成椭圆形且体积缩小。如将花粉保持在15～18℃及相对湿度5～15％环境下,则花粉发芽能力可保持40天。
Beet flower bisexual flowers, in the flowering of 3 to 5 hours, the secretion of a slightly aromatic flavor of trimethylamine juice. Sugar beet bloom generally lasts 20 to 40 days. Longitudinal cracking of anthers after maturity, loose powder within 20 to 30 minutes is completed, 6 hours after anthers shedding. Pollen grains are spherical, when the flowering encountered 35 ℃ above the high temperature, the pollen grains can become oval and the volume decreases. If the pollen is maintained at 15 ~ 18 ℃ and relative humidity 5 ~ 15% environment, pollen germination capacity can be maintained for 40 days.
