Effect of seed vigor and sowing densities on the yield and physiological potential of wheat seeds

Abstract: Initial seed vigor and sowing density interact in establishment of plants the field, can thus affect expression plasticity wheat crop yield physiological quality seeds produced. The aim this study was to evaluate effect levels combination with densities on potential seeds. cultivars BRS Gralha-Azul Sabiá were used a randomized block experimental design 2 × 4 factorial arrangement, four replications. treatments consisted high low (150, 250, 350, 450 seeds.m-2). following evaluations made: yield, germination, first germination count, seedling length, dry matter, accelerated aging, emergence speed index, sand. An increase favors both cultivars; however, it reduces produced by cultivar Gralha-Azul, especially originating from For Sabiá, an decreases performance
