Summary

IN ORDER TO OBTAIN DORMANT SEEDS, IN A REPRODUCIBLE WAY, BARLEY (HORDEUM VULGARE L. CULTIVAR SONJA) WAS GROWN IN A PHYTOTRON. DIFFERENT TEMPERATURE TREATMENTS, TIMES OF LIGHT EXPOSURE AND ARTIFICIAL RAIN APPLIED DURING THE GROWTH AND RIPENING OF GRAINS, RESULTED IN CHANGES IN THEIR GERMINATING PROPERTIES ON HARVESTING. A FRESH TEMPERATURE, EG 285 K (12 DEG C), SEEMS TO BE AN ESSENTIAL FACTOR FOR OBTAINING STRONG DORMANCY, WHEREAS RAIN HAS RATHER A CONTRARY EFFECT.
