Excised stem sections from growing plants of Populus tremula L. and Pisum sativum L. including lateral buds were treated with indole‐3‐acetic acid in a phosphate buffer solution. In control sections the level of the abscisic acid‐like inhibitor decreased strongly during 24 h as did the level of the endogenous auxin. Exogenous indoleacetic acid counteracted the decrease in the inhibitor level to a considerable extent. Implications of this auxin effect in relation to apical dominance are discussed.
