Packaging of soybean seeds stored in different environments

Abstract

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.
