A study of energy state and chemical composition of pod walls and seeds of maturing rape (Brassica napus L.) was conducted on two varieties, Victor and Gorczanski. Total adenosine phosphates, ATP, and adenylate energy charge increased with increasing cell number and cellular synthesis during the early stages, remained high at maximum dry weight accumulation and maximum substrate influx time, and decreased with ripening. A temporal control of energy supply and ATP concentration is evident in developing tissues with determined functions; whereas the association of a high energy charge and active cellular biosynthesis occurs only in tissues with a stabilized cell number.
