Preparation of [14C]-gibberellic acid
Phytochemistry, 1973Abstract A combination of a chemical and a microbiological method is described for the preparation of [14C]-gibberellic acid.

Gibberellic Acid and Vernalization
Nature, 1958SEVERAL workers1,2 have reported that treatment with gibberellic acid induces early flowering in certain biennial plants in the same season and thus replaces their normal low-temperature requirement. In these biennial plants, extension growth and flowering go hand in hand, and it is quite likely that gibberellic acid replaces vernalization treatment ...

Gibberellic Acid and Osmotic Pressure
Nature, 1960VARIOUS visual responses of the plant to gibberellic acid give reason for thinking that the osmotic pressure of the cell sap is influenced also, for as well the stimulation of cell elongation, paler leaf colour and reduction in slowing-up of growth due to planting out3 may indicate an improved water-uptake and thus a decrease of the osmotic pressure1 ...

GIBBERELLIC ACID PRODUCTION BY FUNGI
Madras Agricultural Journal, 1999Fifteen fungal cultures including one type strain. Gibberella fujikuroi were screened for gibberellic acid production using Liquid Surface Fermentation (LSF) and Submerged Fermentation (SmF) techniques. G. fujikuroi produced the highest quantity of GA, followed by Botryodiplodia theobromae in both the fermentation processes. In general gibberellic acid

Effects of Gibberellic Acid on Nicotiana Plants
Nature, 1958THE physiological action and practical application of gibberellic acid are well known (H. Seltman, private communication and refs. 1 and 2). Tests were conducted to investigate its possible application to the control of the alkaloid content and plant development of different Nicotiana species. Gibberellic acid was supplied by Eli Lilly and Co.

Laboratory fermentation of gibberellic acid
Folia Microbiologica, 1960In studying the fermentation conditions suitable for gibberellic acid production, 6 collection strains ofFusarium moniliforme andGibberella fujikuroi were used. The strain used was of decisive importance for the yield and composition of the effective metabolite.

Gibberellic acid—Binding proteins from pea stems
Planta, 1976The formation of complexes of gibberellic acid (GA3) and proteins under in vitro conditions was studied. It was shown that labelled GA3 binds to soluble cytoplasmic proteins, although a considerable amount of radioactivity remains in the pellet containing nuclei and cell debris. GA3-protein complexes are excluded from Sephadex G-10 column with the void

Journal of the Science of Food and Agriculture, 1960
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.
