Three alfalfa clones related by descent, but carrying genes producing simple (sl), trifoliolate (tf), and multifoliolate (mf) leaves, respectively, responded differently to daily treatment with indoleacetic acid (IAA), gibberellic acid (GA), and triiodobenzoic acid (TIBA). Plant height, leaflet and floral characteristics, and selfed‐seed set of the tf clone were comparatively stable under all treatments, whereas sl and mf clones were very sensitive and affected both positively and negatively by growth regulators. Results indicated that GA may be useful in enhancing the growth and seed production of specific stocks.
