Gibberellic acid PGR Growth Regulators In Plants CAS 77-06-5
Description:
Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elong
ation of cells. It affects decomposition of plants and helps plants grow if used in small amounts,
but eventually plants develop tolerance to it[citation needed].

Application:
Has a variety of applications, e.g. to improve fruit setting of clementines and pears (especially Wi
lliam pears); to loosen and elongate clusters and increase berry size in grapes; to control fruit ma
turity by delaying development of the yellow colour in lemons; to reduce rind stain and retard rind
ageing in navel oranges; to counteract the effects of cherry yellows virus diseases in sour cherrie
s; to produce uniform seedling growth in rice; to promote elongation of winter celery crop; to indu
ce uniform bolting and increase seed production in lettuce for seed; to break dormancy and stim
ulate
sprouting in seed potatoes; to extend the picking season by hastening maturity in artichokes; to
increase the yield in forced rhubarb; to increase the malting quality of barley; to produce brighte
r-coloured, firmer fruit, and to increase the size of sweet cherries; to increase yields and aid har
vesting of hops; to reduce internal browning and increase yields of Italian prunes; to increase fru
it set and yields of tangelos and tangerines; to improve fruit setting in blueberries; to advance flo
wering and increase the yield of strawberries; and also a variety of applications on ornamentals.
Application rates up to 80 g/a per application, depending on desired effect.

| Properties | Mol. wt. 346.4 M.f. C19H22O6 Form Crystalline solid. M.p. 223-225 ºC (ATXht98140 decomp.ATXht0 ) Solubility In water 5 g/l (room temperature). Soluble in methanol, ethanol, , and aqueous alkalis; slightly soluble in diethyl and ethyl acetate. Insoluble in chloroform. Potassium, sodium, and ammonium salts: Readily soluble in water (potassium salt 50 g/l). Stability Dry gibberellic acid is stable at room temperature, but slowly undergoes hydrolysis in aqueous or aqueous-alcoholic solutions, ATXht98145 DT50 (20 ºC) c.ATXht0 14 d (ATXht981151 pHATXht0 3-4), 14 d (ATXht981151 pHATXht0 7). In alkalis, undergoes a rearrangement to less biologically-active compounds. Decomposed by heat. |
| Mode of Action: | Acts as a plant growth regulator on account of its physiological and morphological effects in extremely low concentrations. Translocated. Generally affects only the plant parts above the soil surface. |
