Gibberellic acid Gibberellin

Infrared spectra of gibberellic acid, gibberellins Au A2, A3, and A4, and aZZo-gibberic acid were kindly furnished by Abbott Laboratories. [Pg.131]

A number of papers on the biological activity of gibberellins and their derivatives have appeared. The stimulation of plant mRNA synthesis by gibberellic acid has been noted. [Pg.138]

Gibberellic acid and related compounds, referred to genetically as gibberellins, form another class of naturally occurring, plant-growth regulators... [Pg.416]

These compounds were originally isolated from a parasitic fungus that causes excessive leaf elongation in nee plants. The mechanisms and applications of this group of compounds are described in Gibberellic Acid and Gibberellin Plant Growth Hormones. [Pg.1314]

PLANT HORMONES (Gibberellins). See Gibberellic Acid and Gibberellin Plant Growth Hormones. [Pg.1314]

Gibberellic acid is obtained most readily pure and in quantity and knowledge of the chemistry of the gibberellins comes largely from study of the chemistry of... [Pg.3]

Gibberellins which have a saturated ring A undergo epimerization at C-2 with dilute alkali at room temperature, presumably by a reversed aldol mechanism via intermediate (XXXIII) as first suggested by J. W. Comforth (3a). This epimerization has been shown to occur with gibberellin At and its methyl ester (XXXIV), with both C-8 epimeric tetrahydro derivatives of gibberellic acid and... [Pg.8]
