Avaliação da qualidade de sementes de duas cultivares de gergelim em diferentes espaçamentos.

Abstract

Poor seed quality is a major problem facing producers in the Northeast region of Brazil. Witch this, the present work aimed to evaluate the physiological quality of seeds of two sesame cultivars in different planting configurations. The experiment was conducted from July to August 2019, at the Seed Analysis Laboratory (LAS) belonging to the Department of Phytotechnics and Environmental Sciences (DFCA) of the Federal University of Paraíba (UFPB), Campus II, Areia, Paraíba, Brazil. Were used. seeds of cultivar BRS Seda and Anahí obtained from a survey with different planting configurations in the 2019 agricultural year. The statistical design was completely randomized, with treatments distributed in a 2 x 3 factorial scheme, with two sesame cultivars and three spacings (E1, E2 and E3) using four subsamples with 50 seeds. The characteristics analyzed were: First count, Germination, Germination speed index (IVG), Moisture, Seedling length (aerial part and root) and Weight of one thousand seeds. The results showed significant effects between the cultivars with superiority of Anahí in root length and weight of one thousand seeds and superiority of BRS Seda in aerial part length and the spacing in the weight of one thousand seeds with superiority of spacing 2 and 3 in relation to spacing 1. It can be concluded that cultivar Anahí and the adoption of spacing 2 and 3 favor the physiological quality of sesame seeds.
