Seeds of three forage plant species, cocksfoot, tall fescue and perennial ryegrass with good amount of dormancy were chemically treated (25%, 50%, 75% and 98% H2SO4) for different durations and exposed to different temperatures (40 degrees C, 50 degrees C, 60 degrees C, 70 degrees C, 80 degrees C and 90 degrees C) for varying periods with an aim to decrease seed dormancy and increase seed germination. Three groups of seeds based on after ripening period of 0, 3 and 8 months were subjected to these treatments. Immediately after harvest, germination of cocksfoot and tall fescue seeds increased by 24%, but only 13% in perennial ryegrass. Three months after harvest it was possible to increase germination by 20% (cocksfoot), 18% (tall fescue) and 6% (perennial ryegrass). Eight months after harvest it was still possible to increase seed germination of cocksfoot and tall fescue by 4-5% whereas, in ryegrass dormancy was completely lost after 8 months storage
