Application of gibberellin at different staged of growth induced female or sterile spikelets in the tassel. Treatments at early reproductive stages were most effective in producing tassels with many female spikelets. Sterile tassels were produced in latter treatments. The female spikelets induced by gibberellin had an upper female floret and a lower aborted floret. The upper female floret had a pistil and three rudimentary stamens. This structure was the same as a female spikelet of the ear. From these observations and the fact that both the stamens and the pistil differentiate in the florets of the tassel, it is concluded that gibberellin induces female spikelets through the promotion of the pistl development and inhibition of the stamen.
