Detailed Product Description
Gibberellic acid 10% Tablet Plant Growth Regulator
Description:
Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elongation 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.

Applications:
Has a variety of applications, e.g. to improve fruit setting of clementines and pears (especially William pears); to loosen and elongate clusters and increase berry size in grapes; to control fruit maturity 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 cherries; to produce uniform seedling growth in rice; to promote elongation of winter celery crop; to induce uniform bolting and increase seed production in lettuce for seed; to break dormancy and stimulate
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 brighter-coloured, firmer fruit, and to increase the size of sweet cherries; to increase yields and aid harvesting of hops; to reduce internal browning and increase yields of Italian prunes; to increase fruit set and yields of tangelos and tangerines; to improve fruit setting in blueberries; to advance flowering 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, DT50 (20 ºC) c. 14 d ( pH 3-4), 14 d ( pH 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. |

Toxicity:
|
Oral Acute oral LD50 for rats and mice >15 000 mg / kg .
Skin and eye Acute percutaneous LD50 for rats >2000 A mg /kg. Non-irritating to skin and eyes.
