The soaking of sweet orange seeds in water or various concentrations of gibberellic acid for 24 hours prior to planting increased their rate of germination under cool conditions. Larger and more uniform seedlings also followed some of the gibberellic acid seed soak treatments in these tests.

W. H. Brokaw, avocado and citrus nurseryman, Ventura, furnished the seed and grew the seedlings. The gibberellic acid was furnished by the Amdal Company, Agricultural Division of Abbott Laboratories, North Chicago, Illinois.
