Tratamento industrial de sementes de soja e sua influência sobre a qualidade fisiológica ao longo do armazenamento

Abstract

The treatment of soybean seeds is a technic economically recommended to seed protect against biotic and abiotic factors that may decrease their physiological quality. The objective of this work was analyse physiological quality of the seeds submitted to several mixtures of products by seed treatment. The experiment was performed with soybean seeds, cultivar NS6700IPRO, the treatment and physiological quality tests were conducted at BioGrow seed lab in São Paulo. The seeds were treated in Momesso machine model L5-K, the dose utilized was 500mL.100Kg-1 of seeds, so the seeds were storage on environment temperature. It was realized 11 treatments and evaluated at 0; 45; 90; 135 and 180 days after seeds treatment. It’s concluded that is possible to make the seeds treatment with 180 days before seeding for the cultivarNS6700IPRO on these conditions. All of tested treatments contributed to maintenance of quality of the seeds during storage.
