Related to Gibberellins: gibberellic acid, abscisic acid


Any of several plant hormones, such as gibberellic acid, that stimulate stem elongation, seed germination, and other physiological processes.

[From New Latin Gibberella (fujikoroī), the fungus from which a gibberellin was first isolated, from Latin gibberella, feminine diminutive of gibber, hump (from the humplike shape of the genus's perithecia).]

For instance, it has been suggested that the microorganisms present on the WL have the ability to produce several plant growth regulators, such as indoleacetic acids (auxins), gibberellins and cytokinins which have been associated with the greater growth of ornamental plants, vegetables and enhanced crop yields (Islam et al.
