Abstract Artificial refrigeration is sufficient for maintaining the quality of soybean seeds in storage in processing plants, but when lots are distributed to rural producers, they are often kept in natural environments, without temperature or relative humidity control, which decreases their germination rates. This research aimed to evaluate different storage conditions and technological packaging for soybean seeds. The first stage evaluated the quality of soybean seeds stored at different temperatures for up to one year in raffia bags with or without polyethylene inner liners. The second stage evaluated the quality of soybean seeds stored in a natural atmosphere in raffia or laminated packaging, in a modified atmosphere with polyethylene packaging, in a refrigerated atmosphere with raffia or laminated packaging, or in a modified and refrigerated atmosphere with polyethylene packaging. An increase in storage time had a negative influence on the quality of the stored seeds. Storage temperature was the main influence in the reduction in seed physiological quality. Storage of soybean seeds in raffia packaging coated with polyethylene in a natural-temperature environment resulted in seeds retaining similar physical and physiological qualities to those stored under refrigeration. Raffia packaging coated with laminated material maintained the best physical and physiological quality of soybean seeds stored over time. Optimal packaging technology with laminated coating in “big bag” format has replaced the conditioning of storage environments with the maintenance of the quality of soybean seeds over time. The packaging technology is an excellent alternative for the soybean processing units.

大豆种子储存：包装技术和储存环境条件

摘要 人工冷藏足以保持加工厂储存的大豆种子的质量，但当大量分发给农村生产者时，它们往往被保存在自然环境中，没有温度或相对湿度控制，这会降低其发芽率。本研究旨在评估大豆种子的不同储存条件和技术包装。第一阶段评估大豆种子在不同温度下储存在带或不带聚乙烯内衬的酒椰纤维袋中长达一年的质量。第二阶段评估在自然气氛中以酒椰纤维或层压包装、在气调与聚乙烯包装中、在冷藏气氛中以酒椰纤维或层压包装储存的大豆种子的质量，或在带有聚乙烯包装的改良和冷藏环境中。储存时间的增加对储存种子的质量有负面影响。贮藏温度是影响种子生理品质下降的主要因素。在自然温度环境下，将大豆种子储存在涂有聚乙烯的酒椰纤维包装中，导致种子保持与冷藏条件下相似的物理和生理特性。随着时间的推移，覆有层压材料的拉菲草包装保持了大豆种子的最佳物理和生理质量。随着时间的推移，“大袋”形式的层压涂层的最佳包装技术已经取代了储存环境的调节，以保持大豆种子的质量。
