Abstract


This work studies the effects of two drying processes on quality soybean seed. This study comparing simultaneously the effects of two drying processes: the dry-aeration process and conventional drying process. Two drying temperatures (60 and 80°C) and two tempering times (30 and 120 min) were investigated. The seed quality variables analyzed were: break tegument and germinating power. Results show that both drying processes were negative effect on quality seed but dry-aeration process cause less damage. The dry-aeration process to less temperature and higher tempering time caused less damage that conventional drying process about germinating power and integrity integument of soybean seed. In dry-aeration process, the higher tempering times (120 min.) show a positive effect on quality soybean seed. For analysis of temperature, the most damages were to higher temperature.
