Influence of Seed Storage Techniques on Germinability and Storability of Cowpea (Vigna unguiculata (L) Walp)

Abstract

<p>This study was set to investigate the germinability and storability of the newly released cowpea genotypes and secondly the influence of different storage materials under ambient storage condition on seed vigour and germination over time. The experiment was laid in a Split-split plot design with four replicates. The main plot was duration (0, 30, 60 and 90 days), while Storage material (polyethylene bag, cotton bag and glass container) was sub plot and the four cowpea genotypes were sub-sub plot. Results from the study showed that irrespective of the cowpea genotypes and storage material used, percentage vigour and germination were significantly affected with time in storage. Seeds stored in cotton bags had the least percentage vigour (57%) and germination (65%) while the highest was recorded for seeds stored in air-tight glass containers. Among all the cowpea genotypes studied, Hewale was found to have poor storage abilities. For better storage of cowpea seeds for a period exceeding 3 months, it is preferable to use glass containers or black polyethylene bags even under ambient condition to maintain seed vigour and germinability.</p>

Calidad fisiológica de la semilla de fríjol caupí (Vigna unguiculata L. Walp.) por conductividad eléctrica y prueba de germinación

“…Studies carried out by Bortey et al (2016) showed that loss of the quality attributes of the seed can occur faster in one genotype than another even when exposed to the same storage conditions, since the genotypes exude solutes at differential rates due to their ability to resist aging. As the imbibition time elapses, more solutes are released to the outside due to the level of deterioration of the cell membranes (Batista et al, 2012).…”

“…Low EC values are associated with good seed quality (Arun et al, 2017). On the other hand, the conventional germination method is the most reliable, despite demanding more time and has been applied in cowpea to be compared with other methods (Bortey et al, 2016;Moura et al, 2017).…”

Review on: Effect of Seed Storage Period and Storage Environment on Seed Quality

“…As seed quality deteriorates during storage, vigour declines before loss in standard germination [30]. Moreover, reported that farmers in the developing world still store their produce including seed under the ambient environment [15]. Some researchers concluded that, storage under ambient conditions has been observed to affect seed quality in general and germination in particular [11].…”

“…For 1000-seed weight determination, 100 seeds were randomly selected and weighted. The weight obtained was then multiplied by ten (Bortey, Sadia & Asibuo, 2016). Hectoliter weight (Kg/hL) was estimated in triplicate using a 1-liter graduated cylinder filled with seeds consistently and uniformly before weighting.…”
