为了研究花粉长期贮存技术,进行此试验。试验结果如下:从温室和田间将甜菜花粉采集来,在5℃,-18℃下贮存,可以贮存一天。在-196℃下贮存,可以贮存一年。花粉湿度12％在液态氮里存放一年,再将此花粉授于雄性不育花上,其育性和新采集的花粉效果一样。所得的种子的发芽情况也和新采集的种子的发芽情况一致。如果花粉在—18℃下贮存一年,其育性、结实和发芽的效果就不如新鲜花粉好。在5℃下贮存一年,花粉基本上失效。
In order to study pollen long-term storage technology, this test was conducted. The test results are as follows: beet pollen collected from the greenhouse and field, at 5 ℃, -18 ℃ storage, can be stored for one day. Storage at -196 ℃, can be stored for one year. 12% of the pollen moisture is stored in liquid nitrogen for one year, and this pollen is given to male sterile flowers for the same fertility as the newly harvested pollen. The germination of the resulting seeds is also consistent with the germination of the newly collected seeds. If pollen is stored at -18 ° C for one year, its fertility, firmness and germination are not as good as fresh pollen. After one year of storage at 5 ° C, the pollen essentially fails.
