Abstract

Abstract:The production of soybeans in the state of Santa Catarina is quite significant in the national context, since the state is recognized for producing seeds with high standards of physiological quality, due to the use of modern technologies and favorable climatic conditions. The aim of this study was to evaluate the physiological quality of soybean seeds produced by major companies in the state of Santa Catarina, analyzed in three seasons: harvesting (reception at UBS), after processing and at the time of sale. The experiment was conducted in the state of Santa Catarina, in the main regions and companies producing commercial soybean seeds: Xanxerê (companies A, B and C), Abelardo Luz (companies D and E), and Campus Novos (companies F and G), in addition to Canoinhas, which was evaluated with a single producer (company H). Data analysis and interpretation of the results showed that the soybean seeds produced in different regions have adequate quality for sowing and germination within the standards required for marketing, except the BRS 295 cultivars and Don Mario 7.0i company "F".

Highlights

The soybean production in the state of Santa Catarina is important on a national scale, primarily due to favorable climatic conditions
The use of high quality seeds is the basis for agriculture production, is related to the ability of the seed perform its vital functions, and that the effects on quality are generally
The physiological seed quality may be affected by genetic factors, adversity during seed development after ripening and physiological processes that occur before and after harvest (Braccini et al, 2001)

Summary

Introduction

The soybean production in the state of Santa Catarina is important on a national scale, primarily due to favorable climatic conditions. There are cooperatives and companies that produce high quality seeds, designed to meet the needs of the domestic and foreign markets, with exports to Paraguay, Uruguay and Argentina. The market demand, the industry’s professionalism and good climatic conditions guarantee significant participation in the Brazilian scene. This makes Santa Catarina among the largest producers in the soybean seed business, with about 86.000 tons during the 2013/14 harvest (Conab, 2014). The physiological seed quality may be affected by genetic factors, adversity during seed development after ripening and physiological processes that occur before and after harvest (Braccini et al, 2001)
