用新鲜花粉和贮存期达10年的花粉,作了一系列人工授粉试验,表明了保持花粉高度生命力和活力所需的环境条件。在处理时,刚提取的花粉,暴露在高达50℃的温度下24小时,具有高度的抵抗力。贮存前必须将含水量降至10％以下,然后置于保持低含水量的容器内放在3℃的冰箱内可达一年。如须贮存更久,干燥处理后的花粉,必须放置在紧密封口的玻璃瓶或塑料袋内,温度调节至-20℃。花粉在真空密封的安瓿内,置于3℃下,至少能保存10年。
A series of artificial pollination experiments were conducted with fresh pollen and pollen that has been stored for 10 years, demonstrating the environmental conditions necessary to maintain the high viability and viability of pollen. At the time of treatment, the freshly harvested pollen is highly resistant to exposure to temperatures up to 50 ° C for 24 hours. The water content must be reduced to less than 10% before storage and then placed in a 3 ° C freezer for up to one year in a container holding a low water content. If it needs to be stored for longer, dried pollen must be placed in tightly sealed glass bottle or plastic bag with the temperature adjusted to -20 ℃. The pollen in a vacuum-tight ampoule placed at 3 ° C for at least 10 years.
