Activity of acetyl CoA carboxylase was determined in germinating and maturing sunflower ( Helianthus annuus L.) cv. Rum Sun Record seeds. A constant decrease was observed in germi nating embryos. Exposure of etioplasts to light intensity of 500 (74 mW . cm −2 ) lux for different time intervals decreased the activity of the enzyme in the embryos. A reverse trend was observed in ripening embryos where the ATP‐Pi exchange rate was found to be directly correlated to the activity of acetyl CoA carboxylase.
