QUALIDADE DE SEMENTES DE CULTIVARES DE FEIJÃO COMUM

Abstract

Seeds are considered to be the most important agricultural input. And for a crop to be successful, seeds are an important part of this process, so the great effort to produce quality seeds, and the success of a crop depends on the quality of the seeds used. Thus, this study aimed to analyze the physical and physiological quality of common bean seeds: BRS Agreste, BRS Esteio, BRS Realce and BRS Pitanga. The analyzed variables were germination pattern, electrical conductivity of seeds, emergence speed index (IVE), degree of humidity, thousand seed mass and seedling dry mass. The cultivar BRS Pitanga showed the highest results for TPG in the laboratory. The cultivars BRS Realce and BRS Agreste had lower content of salts in solution, and have greater vigor for the EC. The cultivar BRS Realce had the highest seed mass. The cultivars BRS Pitanga, BRS Agreste and BRS Realce presented the degree of humidity closest to that recommended for storage. All treatments for Emergency in the Field were superior to the TPG test in the laboratory. The cultivars BRS Agreste and BRS Esteio were the ones that emerged more quickly, showing greater vigor. The cultivars BRS Pitanga, BRS Agreste and BRS Esteio showed greater vigor for the dry mass of seedlings.
