不同贮藏条件下引进扁桃花粉活力变化

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34 d,浓帕烈在44 d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49C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.

Change of Vitality of Introduced Almond Pollen under Different Storage Conditions

【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 days 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℃.
