Abstract
Soybeans were germinated in dark room at 25°C and the weights of the 3 parts (hull, cotyledon and hypocotyl) in germinated beans and the lipid components of them were determined at various periods up to 7 days. The fatty acids composition of total lipids in each part, triglycerides and polar lipid contents of cotyledon were determined.
The results obtained were as follows :
(1) The lipids content in hull and cotyledon decreased slightly during germination of soybean and gradually increased in hypocotyl, whereas the tocopherol content in cotyledon and hypocotyl was decreased continuously and increased in hull.
(2) Triglycerides of cotyledon lipids decreased markedly during germination of soybeans and free fatty acids and polar lipids of this part were increased. More reduction of unsaturated fatty acids was observed in polar lipids than in triglycerides.
(3) Unsaturated fatty acids of phosphatidyl ethanolamine, phosphatidyl choline and phosphatidyl inositol of cotyledon decreased irregularly during germination of soybeans.
