  2. Gibberellin - Wikipedia

    en.wikipedia.org/wiki/Gibberellin

    Gibberellins (GAs) are plant hormones that regulate various developmental processes, including stem elongation, germination, dormancy, flowering, flower development, and leaf and fruit senescence. [1] They are one of the longest-known classes of plant hormone.

  3. Gibberellic acid - Wikipedia

    en.wikipedia.org/wiki/Gibberellic_acid

    Gibberellic acid (also called gibberellin A3 or GA 3) is a hormone found in plants and fungi. [1] Its chemical formula is C 19 H 22 O 6. When purified, it is a white to pale-yellow solid. Plants in their normal state produce large amounts of GA3. It is possible to produce the hormone industrially using microorganisms. [2]

  4. Plant hormone - Wikipedia

    en.wikipedia.org/wiki/Plant_hormone

    Plant hormones (or phytohormones) are signal molecules, ... In other plants, as ABA levels decrease, growth then commences as gibberellin levels increase. Without ABA ...

  5. Bolting (horticulture) - Wikipedia

    en.wikipedia.org/wiki/Bolting_(horticulture)

    Bolting is induced by plant hormones of the gibberellin family, [citation needed] and can occur as a result of several factors, including changes in day length, the prevalence of high temperatures at particular stages in a plant's growth-cycle, and the existence of stresses such as insufficient water or minerals.

  6. Florigen - Wikipedia

    en.wikipedia.org/wiki/Florigen

    Anton Lang showed that several long-day plants and biennials could be made to flower by treatment with gibberellin, even when grown under a non-flower-inducing (or non-inducing) photoperiod. This led to the suggestion that florigen may be made up of two classes of flowering hormones: Gibberellins and Anthesins. [18]

  7. Paclobutrazol - Wikipedia

    en.wikipedia.org/wiki/Paclobutrazol

    Paclobutrazol (PBZ) is the ISO common name for an organic compound that is used as a plant growth retardant and triazole fungicide. [2] [3] It is a known antagonist of the plant hormone gibberellin, acting by inhibiting gibberellin biosynthesis, reducing internodal growth to give stouter stems, increasing root growth, causing early fruitset and increasing seedset in plants such as tomato and ...

  8. Gibberella - Wikipedia

    en.wikipedia.org/wiki/Gibberella

    A substance, gibberellin, was derived from this fungus. Gibberellin is a plant hormone that promotes cell elongation, flower formation, and seedling growth. [2] Gibberella fujikuroi on Gossypium hirsutum

  9. Aleurone - Wikipedia

    en.wikipedia.org/wiki/Aleurone

    During seed germination, the plant embryo produces the hormone gibberellin which triggers the aleurone cells to release α-amylase for the hydrolysis of starch, proteases, and storage proteins into the endosperm. Evidence that G-proteins play a role in the gibberellin signaling events has been obtained. [16]
