Tall fescue (Festuca arundinacea Schreb.),red rubra L.) and cocksfoot (Dactylis glomerata are important fodder grasses, but in seed production, they prone to shedding certain yield losses.In practice, seeds usually harvested at approximately 20-35% moisture content then additionally dried the of 12% or lower.However, prevent shedding, was 45% content.The effects drying temperatures 70, 60, 50, 40, 30 22 °C on germination dormancy tall fescue, red seeds, contents 45, 35 25 %, were observed present study.The analysis done immediately upon drying, three, eight fourteen months later, which corresponds autumn spring sowing time continental part central south-eastern Europe.In all three species, temperature 70°C, regardless content, 60°C combination with a 45%, reduced germination.After months, highest detected 25% 50°C.Furthermore, greatest determined 35% 50°C.After 40-50°C, while corresponding values amounted 22-30°C, respectively.A positive significant correlation established between seedling vigour.
