The Arabidopsis GAI gene defines a signaling pathway that negatively regulates gibberellin
application of 250 mg /liter with increasing percentage of Nitrogen, Phosphorus, Potassium and K/Na (26%, 16%, 8% & 14%), sequentially according to 0% gibberellin
figures (6,7,8 &10), same the way the gibberellin
application led to reduction the Sodium content in leaves approximately 6%, figure (9).
soaking could significantly improve the seed germination rate; low temperature storage could prolong the vitality of gentian seeds.
2002) Loss-of-function of a rice gibberellin
biosynthetic gene, GA20 oxidase (GA20ox-2), led to the rice "green revolution".
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.

Promotion of flowering in black spruce using gibberellins
Researchers at LERGREC initiated a long-term trial in 2007 with the two most successful of the cluster loosening treatments: fruit-zone leaf removal at trace bloom (when the first caps fall off at the beginning of bloom) and bloom applications of gibberellin
(Hed et al.
2] or gibberellin
after stress promoted lower number of seeds dormancy with 22% of water and 12% of Ca[(N[O.
Serrani JC, Fos M, Atares A, Garcia-Martinez JL (2007) Effect of gibberellin
and auxin on parthenocarpic fruit growth induction in the cv.
A3 stimulates adventitious rooting of cuttings from cherry (Prunus avium).
For example, gibberellin
treatment causes a ten-fold increase of a historic H3 variant expression in deepwater rice (van der Knaap & Kende, 1995) and enhances the expression of a histone H1 and three histone H2B variants in tomato, named leH1 and leH2B1-3 respectively.
