ZEA MAYS L. Mutant plants carrying the ramosa-1 (ra-1) gene which effects inflorescence development, were treated with aqueous solutions of several growth substances. Some plants treated with TIBA exhibited tassels with a reduced ra-1 phenotype. Several plants treated with GA produced ears showing little branching. Discussion is centered on evidence which supports the idea that hormone metabolism is part of a genetic control system governing maize inflorescence development at various stages in the pathway.
