Quality of Corn Seeds Stored in Different Types of Packaging and Stress Conditions

Abstract

Corn (Zea mays) is one of the most cultivated poaceae in the world with high agricultural potential. It is propagated through seeds, which sometimes remain stored until the sowing period. Among the various forms of storage, some aspects related to the environment and the type of material that constitutes the packaging may compromise the viability and vigor of these seeds. Therefore, the objective of this study was to evaluate the physiological quality of corn seeds stored in different types of packaging and subjected to conditions of high temperature and relative humidity throughout storage. For this purpose, water content, germination and vigor were evaluated through the cold test. A completely randomized design in a 4 x 4 factorial scheme (packaging x evaluation times) with four replications was used. Data were subjected to analysis of variance and regression, and the means were compared by Tukey test at 5% probability, using the Sisvar 5.3 statistical software. It was concluded that, in 45 days of storage, the water content in corn seeds reached values of up to 13.62%, which resulted in a reduction in the vigor due to high respiration caused by the storage temperature.

Ciência das Plantas: desafios e potencialidades em pesquisa

“…O armazenamento surge como uma ferramenta importante na conservação da viabilidade e vigor das sementes, especialmente quando se utiliza embalagens que atenuam a influência do ambiente externo, diminuindo a interferência na respiração e no processo de deterioração das sementes (CAPILHEIRA et al, 2020). A embalagem em que a semente é armazenada também influência na conservação da qualidade fisiológica (MARCOS-FILHO, 2015).…”

Corn Seeds Stored Under Varying Storage Conditions

“…Storage plays a crucial role in maintaining the viability and vigor of corn seeds. Particularly noteworthy is the use of packaging that mitigates the impact of the external environment, which can influence respiration and lead to the subsequent deterioration of the seeds (Capilheira et al, 2020).…”

“…Polyethylene (Jaques et al, 2022) or hermetic packaging (Capilheira et al, 2019;Capilheira et al, 2020;Hornke et al, 2020) has been used in several studies to preserve the physiological seed quality. Considering these aspects, this study aimed to evaluate the physiological quality of corn seeds stored in different packaging and subjected to storage conditions in the central region of Brazil.…”
