VARIABLE responses to applications of gibberellic acid have been reported for dwarfs of several plant species. Brian and Hemming (4) found it possible to virtually eliminate differences in growth rates of tall and dwarf pea varieties by treating the dwarfs with gibberellic acid. Phinney (7) reported that genetically different dwarf mutants of maize could be induced to grow at rates similar to normal plants by treatment with gibberellic acid. Normal plants failed to respond to less than 0.5 /ig. of gibberellic acid per plant, but certain dwarfs responded to as little as
