研究了以铝箔袋真空包装和铝盒非真空包装的89份小麦种子,在-4~0℃的低温种质库中贮藏11年后,从2种包装方式的种子贮藏后的检测发芽率各自与入库前的初始发芽率差异,2种包装方式的种子各自年份间、以及同一年份2种方式间的种子检测发芽率差异,3个层次探讨了2种包装方式的种子在低温贮藏条件的贮藏效果。结果表明,通过低温贮藏11年的小麦种子生活力测定,82%的材料在低温保存后其种子平均发芽率高于初始发芽率,而10年后发芽率才出现较初始发芽率明显下降,铝箔袋包装的种子发芽率下降幅度小于铝盒包装的,且差异达到显著,铝箔袋真空密封包装的贮藏效果明显好于非真空包装的种子。
Germination percentage of 89 accessions wheat germplasm stored-4~0℃ packed in vacuum aluminum foil bag and non-vacuum aluminum box were tested.Disussed the effect of storage method form three levels:the difference of germination percentage of two package methods for seeds stored at low temperature and initial germination percentage before stores, the difference of germination percentage of two package methods for seeds between storage years and the difference of germination percentage between two package methods in the same year. The result showed:the viability of wheat germplasm stored at low temperature were tested, the 82 percent of materials of mean germination percentage was higher than initial germination percentage,but ten years later, germination percentages were obviously decreased than initial germination percentage,and the germination percentage of aluminum foil bag were reduced of less than aluminum box and the difference was significant, the method of sealing up in aluminum foil bag showed best effect.
