SUMMARY When the ears of wheat were grown after anthesis at temperatures different from the rest of the plant the gibberellin content of the ears increased more rapidly at higher ear temperatures, whilst the plant temperature had little effect. This greater rate of gibberellin accumulation was associated with a greater rate of ear dry weight increase. Wheat ears detached from the plant increased their gibberellin content over 4 days when provided with sucrose and ewfkaurene.
