White powder gibberellic acid plant growth regulator 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 morphol
ogical effects in extremely low concentrations. Translocated. Generally affects only the plan
t parts above the soil surface.
Gibberellic acid is a simple gibberellin, a pentacyclic diterpene acid promoting growth and e
longation of cells. It affects decomposition of plants and helps plants grow if used in small a
mounts, but eventually plants develop tolerance to it[citation needed].

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; 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 fr
uit 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 ornament
