Excerpt from Vernalization Experiments With Forage Crops
Seed of white lupine, crimson clover, hairy vetch, and Austrian Winter field pea vernalized or started into growth by the addition of moisture and then kept for a period of 40 days at 0° C. When subsequently planted came into flower and fruit, while seed not so treated remained in the vegetative stage or came into bloom at a later date. Seed of white sweetclover and red clover showed no response, but this may have been due to insufficient treatment.
Seed of foxtail millet, Sudan grass, soybean, and crotalaria mois tened and kept for a _period of 5 to 9 days at high temperatures showed in most cases decreased vigor and in no case did such treatment advance the time of maturing.
Seed moistened and started into growth activity and subsequently dried started into growth sooner than seed not so treated.
