Simulação da duração e da temperatura de transporte de espigas de milho da colheita à secagem de sementes

Abstract

The high quality seeds production envolves apply planning and decision making strategies on the companies. For this purpose, the factors concerning that can impact on seed quality should be understood. Thus, understanding each step of process helps to achieve faster, more accurate decision making. The transport time between harvest and seed drying can rise the seed deterioration. This project aimed to the period and temperature that impact on seed quality of the inbred line (Hybrid) A, harvested with 27% of moisture during of the transport. The assessments were with four temperatures (20, 30, 40 and 50 Celsius degree) and three periods (6, 12 and 24 hours after harvested), the lab test for germination was under the rules of RAS and vigor was under cold test modificated – C-Sat (Syngenta’s method). So, the period of transport has been shown to be a critical factor to the quality of the seeds, and that temperature must be tracked especially when above 40 C.
