Cell division and gibberellic acid
Experimental Cell Research, 1959Abstract In two rosette plants, Hyoscyamus niger and Samolus parviflorus , gibberellic acid causes a substantial increase in cell division in the tissues immediately underlying the apex. As the treatment continues an elongate stem is produced and, for at least 72 hours, the period considered in this study, the subapical zone of cell division ...

Shedding light on gibberellic acid signalling
Current Opinion in Plant Biology, 2009Gibberellic acid (GA) promotes a range of developmental and growth processes in plants, the most well-known being germination, elongation growth and flowering time. DELLA repressors are the key players of the pathway. Their presence or their GA-dependent turnover via the 26S proteasome correlates to a large extent with the repression or derepression ...

A Simple Bioassay for Gibberellic Acid
Nature, 1966IN his review of 1965, Paleg1 outlined the many biological tests that have been used as quantitative assays for gibberellins. The lettuce hypocotyl test is perhaps the simplest to carry out, but the lowest concentration that can be reliably assayed is only 0.1 mg/1.

Gibberellins (GAs) are a group of diterpenoid acids that function as plant growth regulators influencing a range of developmental processes in higher plants. One of them, gibberellic acid (GA3), has received the greatest attention. It affects stem elongation, germination, elimination of dormancy, flowering, sex expression, enzyme induction and leaf and

Gibberellic Acid and Growth Correlations
Nature, 1959AMONG other effects, gibberellic acid may alter plant-growth correlations by decreasing the inhibitory action of leaves and storage organs. Previous work1–3 has shown that species of Bryophyllum, B. crenatum, B. verticillatum and B. daigremontanum do not flower if kept continually under either long- or short-day conditions.

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 ...

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.
