gib·ber·el·lin

 (jĭb′ə-rĕl′ĭn)
n.
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).]

Among the types of plant growth regulators such as auxins, cytokinins, gibberellins, and others, gibberellins accounted for the largest market share, followed by cytokinins and auxins.
The application of auxins or ethylene feminizes Cannabis (Heslop-Harrison, 1956; Mohan Ram & Jaiswal, 1970), whereas gibberellins are masculinizing (Atal, 1959; Chailakhan, 1979).
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.

From the point of view of seed physiology, this action of temperature is related to changes in the activity of gibberellins and abscisic acid in the seed.

The growth- retarding properties of the triazoles, like many other growth retardants, are likely attributed to interference with gibberellins biosynthesis, hence these compounds are often referred to as "antigibberellins" (Davis et al.
