Plant growth regulator
Product name: Gibberellic acid ( GA3)
CAS No. [77-06-5]
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
Use:
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 fiuit 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.
