S ummary1 Changes in fats, sugars and starch have been followed in grains of A. sativa during the first few days in germination conditions. 2 A decrease in fats and some of the sugars present in the dry grain was evident during the first day; the utilization of starch did not commence until between the first and second days. 3 It is concluded that the metabolism of the germinating grain is not initially dependent on starch‐derived materials. Fats and some of the sugars are suggested as likely alternatives for respiratory substrates. 4 The relevance of this to previous studies on the development of starch‐degrading enzymes in germinating and dormant grains of Avena spp. is discussed.
