QUALIDADE DE SEMENTES DE FEIJÕES PARA A AGRICULTURA FAMILIAR

Abstract

Brazil stands out as the third largest bean producer in the world and although many farmers use improved seeds for planting, most beans are grown by small farmers who keep part of their production to be used in the new crop. Thus, research is needed to provide information on the physiological, physical and sanitary quality of special bean seeds. The objective of this study was to characterize the physical, physiological and sanitary quality of seeds of two - year special bean varieties cultivated in Carmo do Rio Verde - GO. The tests of physical purity, moisture degree, mass of 1000 seeds, germination, electrical conductivity, tetrazolium and sanity were done in the Laboratory of Seed Analysis and seedlings emergence was done in a greenhouse of the Goiano Federal Institute - Campus Ceres. The moisture content of the analyzed seeds is within the standards established by the legislation. The purity of the seeds is not within the commercial standard. The physiological quality of bean seeds was genotype dependent. The effect of the genotype on the electrical conductivity results of the seeds was evidenced. The Jalo and Roxinho beans grown in the Carmo region of Rio Verde have germination above 95%. The special bean varieties studied in this study had the physical, physiological and sanitary potential of the appropriate seeds, thus possessing the necessary characteristics for their use in the production of grains for the family farmers.
