摘要
[目的]确定引进扁桃花粉贮藏条件及花粉活力保持时间。[方法]对6个扁桃品种浓帕烈、索奴拉、米森、汤姆逊、尼普鲁斯和布特的花粉进行贮藏，研究其萌发率及花粉活力。[结果]贮藏浓帕烈、索奴拉、米森、汤姆逊、尼普鲁斯和布特花粉，其常温下与4℃下贮藏相比，花粉活力保持天数仅多1。3d，而在-19℃下汤姆逊、尼普鲁斯和布特花粉活力保持天数为34d，浓帕烈在44d后花粉萌发率仍在77％，贮藏的各扁桃品种花粉活力保持天数比4℃贮藏下多4倍以上。[结论]引进扁桃的花粉在-19℃下贮藏较为适宜。
[ Objective ] To determine the storage conditions of introduced almond pollen and time of maintaining its pollen vigour. [ Method ] The pollen of six almond varieties including Nonpareil, Sonora, Mission, Thompson, Ne puls ultra and Butte were storaged to study the chang of their germination rate . [Result]The result shows that with the increase of the storage time, pollen vitality fell gradually under the different temperature conditions,the pollen vitality could be maintained for 7 - 14 clays under room temperature, the pollen vitality of almord storaged under room temperature were could be maintained for only more 1 - 3 days than that under 4℃, while Thompson and Napuls ultra and Butte were maintained for 34 days, the pollen germination rate of Nonpareil still were 77 % after 44 days. The storaged pollen vitality of all the almond varieties could be maintained for more 4 times than that under 40℃[ Conclusion]The introduced almond pollen was fitlod to be stovaged at - 19℃.
