Synopsis Four dwarf and semidwarf wheat varieties were not induced to attain a standard height by treatment with gibberellic acid, and they responded less to treatment than the standard‐height varieties. Optimum growth response occurred generally after injections with 100‐ppm of gibberellic acid, whereas inhibition was sometimes observed after treatment with 1000‐ppm. Spike emergence of 3 of the 6 varieties was hastened. Treatment affected internodes of three varieties differently depending on both variety and concentration of gibberellic acid.
