Packaging of soybean seeds stored in different environments

O objetivo deste trabalho foi avaliar embalagens para a conservação da qualidade de sementes de soja (Glycine max) estocadas em diferentes ambientes. O delineamento experimental foi inteiramente casualizado, em arranjo fatorial com seis condições de armazenamento de sementes: atmosfera natural (NA), atmosfera de embalagem laminada (LPA), atmosfera modificada em embalagem de polietileno (MAPP), atmosfera refrigerada em embalagem de ráfia (RARP), atmosfera refrigerada em embalagem laminada (RALP), e atmosfera modificada e refrigerada em embalagem de polietileno (MRAPP), com quatro tempos de armazenamento (zero, dois, quatro e seis meses). O tempo de armazenamento reduz a qualidade das sementes de soja após dois meses em todas as embalagens testadas. A germinação das sementes de soja foi mantida nas seguintes embalagens: LPA, RARP, RALP e MRAPP. A LPA é a embalagem mais eficiente para as sementes de soja, que apresentam maior percentual de germinação pelo maior tempo de armazenamento, sem necessitar de modificação e/ou refrigeração do ambiente de armazenamento.The objective of this work was to evaluate packaging for preserving the quality of soybean (Glycine max) seeds stored in different environments. The experiment design was completely randomized, in a factorial arrangment with six seed storage conditions: natural atmosphere (NA), laminated packaging atmosphere (LPA), modified atmosphere in polyethylene packaging (MAPP), refrigerated atmosphere in raffia packaging (RARP), refrigerated atmosphere in laminated packaging (RALP), and modified and refrigerated atmosphere in polyethylene packaging (MRAPP), with four storage times (zero, two, four, and six months). Storage time reduces the quality of soybean seeds after two months in all tested packaging. The germination of the soybean seeds was maintained in the following packaging: LPA, RARP, RALP, and MRAPP. LPA is the most efficient packaging for soybean seeds, which show the highest percentage of germination for the longest storage time, without requiring any modification or refrigeration of the atmospheric storage environment
