| Abstract: | Growth responses of lettuce seedlings to cyclic AMP and gibberellicacid were studied. Both cyclic AMP and sodium dibutyryl cyclicAMP significantly stimulated hypocotyl elongation, althoughelongation by cyclic AMP was smaller than that by gibberellicacid. Substances related to cyclic AMP, i.e. 5'-AMP, 5'-ADPand 5'-ATP, had no growth promoting effects. Examination of mechanical properties of the cell wall by a stress-relaxationtechnique indicated that both cyclic AMP and gibberellic acidcaused cell wall loosening when they stimulated hypocotyl elongation.
