Rapid loss of seed germination and vigor during storage is a common problem faced by rice farmers and seed producers. Present study investigated the influence of packing material and seed moisture content (SMC) at packing on seed germination and vigor during storage in rice. Seeds of three popular improved rice varieties were stored in polythene and poly-sack (woven polyethylene) with 11% and 13% SMC at packing. Standard seed germination (SSG), glasshouse seedling emergence (GSE) and seed vigor as measured by field emergence (FE) were recorded at monthly intervals in storage. Seed germination and vigor could be maintained unchanged for the longest duration in polythene at 11% SMC. In Bg 300, SSG remained unchanged for 11 months, GSE for >11 months and FE for 10 months. In Bg 352 and Bg 358, SSG remained the same for eight months, GSE for 10 months and FE for nine months. Therefore, polythene is a better alternative to poly-sack which is the commonly used material at present and SMC 11% is better than 13% for storage of seed paddy in polythene.

贮藏期间种子发芽和活力迅速丧失是稻农和种子生产者面临的普遍问题。本研究调查了包装材料和种子水分含量（SMC）对水稻贮藏过程中种子萌发和活力的影响。三种流行的改良水稻品种的种子在包装时储存在聚乙烯和聚乙烯袋（编织聚乙烯）中，SMC 分别为 11% 和 13%。标准种子发芽 (SSG)、温室出苗 (GSE) 和通过田间出苗 (FE) 测量的种子活力在储存中按月间隔记录。在 11% SMC 的聚乙烯中，种子萌发和活力可以保持最长时间不变。在 Bg 300 中，SSG 保持不变 11 个月，GSE 保持>11 个月，FE 保持 10 个月不变。在 Bg 352 和 Bg 358 中，SSG 保持不变八个月，GSE 10 个月，FE 9 个月。因此，聚乙烯是一种更好的替代品，聚乙烯袋是目前常用的材料，SMC 11% 比 13% 更适合在聚乙烯中储存种子稻。
