The gibberellin biosynthesis inhibitor uniconazol reduces both the elongation and indole‐3‐acetic acid content of growing Pisum sativum cv. Alaska intemodes. Both internode growth and indole‐3‐acetic acid content in uniconazol‐treated plants can be elevated by gibberellin A3 treatment. The lengths of the growing intemodes are directly related to the indole‐3‐acetic acid contents.
