Journal of Small Fruit & Viticulture, 1996
Field and growth chamber experiments, as well as grower trials, were conducted to determine the effects of GA3 sprays on fruit set and yield of rabbiteye blueberry (Vaccinium ashei Reade) in north Florida and south Georgia. Multiple GA3 sprays at different stages during bloom increased fruit set and yield in field experiments in Florida and in grower ...

Journal of the Institute of Brewing, 1961
While It has been confirmed that the application of 1–3 p.p.m. gibberellic acid accelerates the rate of malt modification and produces high laboratory extracts, treatments at these levels can lead to over-modification and excessive colour formation; in addition, the cost of the process is uneconomic.

Selective reduction of gibberellic acid
Journal of Applied Chemistry, 1963AbstractSelective reduction of the 3, 4‐ethylenic bond in gibberellic acid (V), its methyl ester and the related compound (VIII), occurs, with varying degree of concomitant hydrogenolysis of the lactone ring, on hydrogenation with a palladised barium carbonate catalyst in the presence of pyridine or other organic base.

AbstractA number of derivatives of gibberellic acid have been prepared and their growth‐promoting activities compared. Eleven salts and four acyl derivatives showed activities similar to that of gibberellic acid when applied to the roots or to the leaves of dwarf pea seedlings.

Detection of Gibberellic Acid in Azotobacter Cultures
Nature, 1961IT is known that Azotobacter cultures can affect the germination of seeds and growth of plants. It is assumed that this influence is due to the presence of physiologically active substances and vitamins in the cultures. Actually, indole-3-acetic acid has been detected in Azotobacter cultures1,2.

Inhibition of Flowering in Poinsettia by Gibberellic Acid
Nature, 1963THE formation of flowers and decorative bracts in poinsettia (Euphorbia pulcherrima Willd.) is induced by short photoperiods1, the plants remaining vegetative in long day-lengths. Among short-day plants the perennial Fragaria spp.2 and Kalanchoe blossfeldiana3 are inhibited from flowering by gibberellin.

Interaction of Gibberellic Acid and Indoleacetic Acid in Impatiens
Science, 1959Gibberellic acid promotes doubling, early flowering, and fruiting directly in Impatiens . It also lengthens the stem, probably through a neutralization of auxin inhibitors. Such a mechanism would leave the growth-promoting auxins unchecked to produce the increased elongation characteristic of gibberellin application.
