Abstract

Fumitory (Fumaria officinalis L.) achenes were after-ripened in moist sand at 4 C for 0, 15, 30, 45, and 60 days. Embryo size in longitudinal section increased 14 times during after-ripening. The percentage of ether soluble lipids and their fatty acids remained constant during the entire after-ripening period. Soluble carbohydrates were the highest at the 45-day period of after-ripening when embryo growth was rapid. The concentration of 70% ethyl alcohol soluble amino acids increased gradually over the first 45 days of after-ripening and decreased over the last 15 days as embryo growth became more rapid.
