摘　　要：This study was conducted to investigate the effects of different packaging methods on seed germination and vigor under a long-term bank storage condition, selecting suitable packaging materials and methods, and comprehensively estimate changes in seed vigor of seeds stored with different packaging materials. Hibiscus cannabinus L. seeds were stored in aluminium box, seed box, glass bottle, POlyethylene film bag, sack and kraft paper bag as packaging materials in a, long-term bank and tested for their seeds germinability, electrical conductivity and field seedling rate after 31 years. The results showed that the kenaf seeds with an initial germination rate of 88% exhibited the germination rates over 79.7% after being stored in the 6 packaging materials for 31 years, the germination rates of seeds packaged with paper bag and sack and of those sealed in film bag and aluminium box showed significantly decreased germination rates, while the seeds sealed in seed boxes and glass bottles exhibited non-significant decreases in seed germination rate, and their germination rates were still above 85%. Seed box and glass bottle were the packaging materials most suitable for long-term safe storage of kenaf seeds with a safe storage period long than 31 years.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。
