Gibberellin can significantly promote the growth of stems and leaves of plants, especially for dwarf plants of hereditary and physiological types; promote germination; can make long-day plants bloom under short-day conditions and shorten the life cycle; It can induce flowering, increase fruit set rate, promote fruit growth, and delay fruit aging. In addition, it can also be used to prevent peeling of the peel; spraying during the flowering period of cotton can reduce the loss of buds; potato soaking can break the dormancy; barley soaking can increase the yield of maltose.
The most prominent role of gibberellin is to accelerate cell elongation (gibberellin can increase the amount of auxin in plants, while auxin directly regulates cell elongation), which also promotes cell division, which promotes cell Enlarged (but does not cause acidification of the cell wall).
The most prominent physiological effect of gibberellin is to promote stem elongation and induce long-day plant twitching and flowering under short-day conditions. Gibberellin plays a regulatory role in seed germination.
Both gibberellin and auxin have a role in promoting plant growth. They are all important plant hormones. The following is a comparison of them:
First, mutual promotion 1, promote plant growth: auxin.
2. Delay leaf senescence: auxin.
3. Inducing callus differentiation into roots or shoots: auxin.
4. Regulate seed germination: gibberellin.
5, promote fruit fruit set and growth: auxin, gibberellin.
Second, mutual antagonism 1, the top advantage: auxin promotes the growth of the top bud, gibberellin promotes the growth of the lateral bud.
2, regulate organ shedding: auxin inhibits flower shedding, and abscisic acid promotes the shedding of leaves, flowers and fruits.
3. Differentiation of bisexual flowers: auxin increases female flowers, and gibberellin causes male flowers to form.
Gibberellin, 1. Promote cell elongation, cause stem elongation and plant growth 2. Release seed, tuber dormancy and promote germination.
Auxin, 1. cause cell differentiation, promote rooting of cuttings, 2. promote fruit development, 3. prevent falling flowers and fruit.
In short, a plant, want Mr. root (add auxin), and then grow high (gibberellin), hormones should be moderate concentration!
