“…The storage of seeds in permeable packagings allows the internal humidity to change with the environment, causing increases or decreases in the water content until reaching hygroscopic equilibrium (Rocha et al, 2017;Moreano et al, 2018;Keneni et al, 2019). Smaniotto et al (2014) evaluated the storage of soybean seeds and observed a reduction in the water content, to 11%, due to the permeability of the packaging, which allowed greater intensities of water vapor exchange with the environment.…”

Storage is a fundamental practice in the control of the physiological quality of seeds, as it is a method that can preserve their viability and vigor for a longer period. Thus, the objective of the present study was to evaluate the storage of chickpea seeds in different packagings, environments, and periods. The completely randomized design was used in a 2 × 2 × 4 factorial scheme, corresponding to two types of packaging (hermetic and Kraft® paper), two storage environments (cold chamber environment and conventional environment), and four storage periods (0, 45, 90, and 135 days), with four replicates. The seeds were placed in Kraft® paper bags and hermetic packagings and stored for 135 days in the environments: cold chamber (14.5 °C and relative air humidity of 65%) and conventional environment (no temperature and relative air humidity control). Every 45 days, seeds were subjected to the following evaluations: determination of water content, germination, first germination count and accelerated aging. In general, the maintenance of the physiological quality of chickpea seeds was verified in Kraft® paper packagings and the cold chamber environment. Storage of chickpea seeds in hermetic packaging must be carried out with seeds with 7% moisture, regardless of the storage environment. The packagings maintained the physiological quality of chickpea seeds for up to 45 days, regardless of the storage environment.

“…In an evaluation of different storage environments at 10˚C, 25˚C, and room temperature, different deterioration rates were verified, influenced by the variation of the water contents. The predominant reaction of seed degradation occurred when the water content of the seeds reached levels below the activation limit for enzymatic lipid peroxidation and sugar hydrolysis [31][32][33].…”

This study aimed to evaluate the quality of seeds of RR and RR2 PRO soybean cultivars stored in ambient air with raffia packaging (ANER), ambient air with laminated packaging (ANEL), modified atmosphere with polyethylene packaging (AMEP), refrigerated atmosphere (1 to 3°C) with raffia packaging (ARER), refrigerated atmosphere (1 to 3°C) with laminated packaging (AREL), and modified (-14 PSI) and refrigerated (1 to 3°C) atmosphere with polyethylene packaging (AMREP), over 6 months of storage. Results showed that the seeds of cultivar RR2 were preserved with better physiological quality. Raffia and polyethylene packaging under natural storage conditions, in a refrigerated and modified atmosphere, did not preserve the seed quality over the storage period. The conditions of storage in ambient air with laminated packaging (ANEL) and in a refrigerated atmosphere with laminated packaging (AREL) reduced the environmental effects of temperature and relative humidity, leading to better results of physiological quality of the seeds. Storage time negatively influenced the physiological quality of seeds, except for AREL and ANEL, which maintained the quality close to that of the initial conditions, over the 6 months of storage. The best alternatives for soybean seeds storage over 6 months are the laminated packaging in a natural environment, matching the refrigerated conditions. The technological laminated packaging can be used as a new alternative for conserving soybean seeds in processing and storage units.

“…The seed lots showed high physical and physiological quality since the reception, and the seeds reached greater purity, germination and vigor throughout the process, since the values increased with each stage. One of the premises of the beneficiation is to remove impurities and damaged or non-standard seeds, raising the quality to the final product (Lopes et al, 2011;Kirchner et al, 2014;Moreano et al, 2018). In control charts, upper control limits (ULC) and lower control limits (LLC) are established to help judge the significance of the variation in product quality.…”

Soybean is a crop of great economic relevance in the world, with seed production being one of the most important sectors of its agro-industrial complex. Processing is one of the final stages of the seeds production process, it aims to remove impurities, select seeds by shape, size and density and pack properly. Monitoring and quality control at different stages of the process ensures that seeds meet storage and market standards. The aim of this study was to evaluate the different stages of processing in the physical and physiological performance of three cultivars of soybean seeds using statistical process control tools. The work was carried out at the seed processing unit with the cultivars M8644 IPRO, M8349 IPRO and M8808 IPRO, with sampling at eight points throughout the process. Water content, physical purity, germination, first count, accelerated aging, tetrazolium (vigor and viability), mechanical damage and electrical conductivity were evaluated. During the process, mean and amplitude control charts were used for each test. The use of control charts made it possible to monitor the process of soybean seed processing, pointing out the methodology as a tool to determine existing problems, to promote continuous improvement in the performance of seed processing.
