| Abstract: | 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. |
