Gibberellic Acid GA3 4%EC Plant Growth Regulators CAS 77-06-5
Description:
Gibberellic acid is a plant growth regulator, cas no is 77-06-5,MF:C19H22O6
Mode of action:Acts as a plant growth regulator on account of its physiological and morphologi
cal effects in extremely low concentrations. Translocated. Generally affects only the plant parts
above the soil surface.
Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and elon
gation of cells. It affects decomposition of plants and helps plants grow if used in small amount
s, 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 fr
uit maturity by delaying development of the yellow colour in lemons; to reduce rind stain and r
etard rind ageing in navel oranges; to counteract the effects of cherry yellows virus diseases i
n sour cherries; to produce uniform seedling growth in rice; to promote elongation of winter ce
lery 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; t
o increase the yield in forced rhubarb; to increase the malting quality of barley; to produce brig
hter-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 increas
e fruit set and yields of tangelos and tangerines; to improve fruit setting in blueberries; to advan
ce flowering and increase the yield of strawberries; and also a variety of applications on orname
ntals. Application rates up to 80 g/a per application, depending on desired effect.
