gib·ber·el·lins

(jib'ĕr-el'inz),
A class of plant growth hormones (auxins) of which over 60 are known; these were first isolated in 1938 from cultures of Gibberella fujikuroi, the fungus causing Bakanese disease in rice. Also found in higher plants; diterpenoid acids available commercially.

The poultry and gibberellins applications alleviated from the negative affect of saline waterfigures (2, 3, 4, 5, 6, 7, 8, 10).
The germination rate of large-leaved gentian seeds were significantly improved after soaking with different concentrations of gibberellins compared with the control group.
Interestingly, this hormone can generate the same effect by decreasing the endogenous synthesis of gibberellin, which is a hormone responsible for cell elongation and division (Pearce et al.

The literature cites that Type-II growth inhibitors used in lawns, such as trinexapac-ethyl and prohexadione-calcium, are not very efficient at avoiding the emergence of flower rachises, because they interfere with the biosynthesis of gibberellins and, consequently, with the reduction of cell elongation (Mittlesteadt et al.
The responses of the 3-node explants to some supplementary sources of different aminoacids and growth regulators indol-3-acetic acid 6- benzylaminopurine and gibberellins A3 were also analysed.
Several factors are involved in the regulation of dormancy, including hormones such as abscisic acid (ABA), gibberellins (GAs), ethylene, cytokinins and others (CARRERA et al.
Previously, steviol was considered as precursor of gibberellic acid due to cis-coupling of B and C rings of tetracyclic hydrocarbon system, typical for gibberellins.
