Armazenamento de sementes de grão-de-bico em embalagem hermética e papel em diferentes ambientes

Abstract

The packaging and the storage environment influence the seeds' physiological quality since the material of the seeds may accelerate the deterioration process. It was resulting in abnormal seedlings. Thus, the objective was to evaluate chickpea seeds' physiological quality stored in airtight packaging and kraft paper, kept in conventional storage and a cold chamber. For the experiment, a lot of chickpea seeds from the cultivar Aleppo was used. A completely randomized experimental design was used in a 2 x 2 x 4 factorial scheme, corresponding to two packaging types (airtight and kraft paper), two environments (cold and conventional chamber), and four storage periods: 0, 45, 90, and 135 days. At the end of each storage interval, the seeds' physiological quality was evaluated by analyzing germination, first count, moisture, and accelerated aging. As a result, there was a significant effect of a triple interaction between the factors of packaging, environments, and storage time. At germination and first count, there was a double interaction of packaging and time factors. As for the accelerated aging factor, there was a significant effect of the double interactions between the packaging and environment factors and between environment and storage times. The kraft paper packaging showed a lower rate of deterioration of chickpea seeds during the 135 days of storage.
