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.

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.

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.
