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 ...

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.

Control of carbohydrase formation by gibberellic acid in barley endosperm
Phytochemistry, 1975 a-Amylase, limit dextrinase and a-glucosidase were induced by gibberellic acid in barley grain from which the embryos had been excised. The responses to different concentrations of gibberellic acid were similar for the three carbohydrases.

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.

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 ...

Gibberellic acid and the growth of crop plants
The Journal of Agricultural Science, 19561. Field trials with gibberellic acid on grass, wheat, potatoes, turnips, carrots, peas, runner beans, lettuce, celery, blackcurrants, kale and maize are described. The effects on plant growth and crop yield were determined.2. The experiments on grassland were carried out between July 1953 and June 1956, and included trials at four different centres ...

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.

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 ...

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 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 ...
