FASCICLED EAR (Fa), a dominant ZEA MAYS L. mutant effecting the form of the inflorescence, was treated with aqueous solutions of a-naphthaleneacetic acid, indoleacetic acid, gibberellic acid, maleic hydrazide and triiodobenzoic acid every three days from the seedling stage until tassel emergence. The mutant responded to a-naphthaleneacetic acid and indoleactic acid in such a manner that certain treated plants developed a normal-appearing ear and tassel. The idea that an ear and tassel shoot meristem is a "plastic" system genetically programmed at specific points in development through a hormonal balance is discussed.
