Apical dominance of intact pea plants ( Pisum sativum L. cv. Alaska) was found to be diminished by high irradiance and by increasing the CO 2 content of the air. Ethephon treatment of young plants resulted in an outgrowth of laterals, but this was significant only when the apical dominance already was weakened by high irradiance and/or CO 2 .
