为了探讨长期库贮藏条件下不同包装对种子发芽率、活力的影响,筛选适宜的种子包装材料和方法并全面评价不同包装的种子长期保存后的活力变化情况。用铝盒、种子盒、玻璃瓶、聚乙烯薄膜袋、布袋和牛皮纸袋6种材料,对南选红麻种子进行包装后,贮藏于长期库内,31年后取出测定它们的种子发芽力、电导率和田间成苗率等。试验结果表明:初始发芽率为88%的6种包装类型的红麻种子贮藏31年后种子发芽率仍然在79.7%以上,用纸袋和布袋包装、薄膜袋和铝盒密封包装的种子发芽率下降明显,用种子盒、玻璃瓶密封包装的种子发芽率下降不明显,发芽率仍保持在85%以上,种子活力高。种子盒和玻璃瓶是红麻种子长期安全贮藏最适宜的包装材料,安全保存期限达31年以上。
In order to investigate the effect of different packages on seed germination rate and vigor under long-term storage conditions, the appropriate seed packaging materials and methods were screened and the changes of vitality of different packaging seeds after long-term storage were evaluated. Seeds of south kenaf were packaged in aluminum boxes, seed boxes, glass bottles, polyethylene film bags, cloth bags and kraft paper bags, and stored in long-term storage. After 31 years, the germinated power of the seeds was measured, Conductivity and field seedling rate and so on. The results showed that the germination rate of seeds of six kinds of kenaf varieties with the initial germination rate of 88% after storage for 31 years was still above 79.7%. The seed germination rate of kenaf seeds packed in paper bags and bags, film bags and aluminum boxes decreased Obviously, with the seed box, sealed glass bottles sealed seed germination rate decreased significantly, the germination rate remained above 85%, high seed vigor. Seed boxes and glass bottles are the most suitable packaging material for long-term safe storage of kenaf seeds, with a safe storage period of over 31 years.
