Abstract
The moisture content of red clover seed proved to be the most important single factor governing its longevity. Life was conserved considerably better in a heated room, on account of its lower relative humidity, than in an unheated granary. Low temperature (32°–41°F.) was shown to be very beneficial for maintaining viability when the moisture content was excessive (10.32 per cent). By replacing the air in the containers with dry CO 2 longevity was increased. A combination of low moisture content, cold storage and replacement of air by dry CO 2 enabled red clover seed to germinate 71 per cent after 23 years’ storage and produce vigorous seedlings. Purple and yellow colours may be retained in a considerable proportion of a red clover seed stock long after all the seeds are dead.
