Abstract/Contents:"Perennial ryegrass seed was dried at temperatures from 50°C to 120°C, the increases of 10°C being made regularly at intervals of 3 hours. The figures for germination capacity obtained immediately after treatment indicated that a lethal zone had been reached with final temperatures above 100°C and moisture contents reduced to 0.09 and 0.00 per cent. It was shown that heat drying to as low as 0.66 per cent moisture at a final temperature of 100°C for 3 hours does not injure the germination capacity over a period of seven years, but after 15 years a greater loss in viability appears than in seed treated less severely. Germination energy figures (6-days' test) rather than germination capacity are a more reliable guide to optimum temperatures, duration of heating, and moisture content in the drying of seed for long-period storage. The most favourable treatment in this series was found to be heating the seed gradually to a maximum temperature of 90°C for 3 hours with a reduction of moisture content to 1.62 per cent. Seed thus treated showed 81 per cent germination after 15 years; for the last eight years the bottles were stored in a cold room, after replacing the air in them with nitrogen."
