Product introduction

MF: C19H22O6
MW: 346.382
CAS: 77-06-5
EINECS: 201-001-0

Chemical properties

Pure product is white crystal, industrial product is white powder. M.p. 233 ~ 235 ℃. It is soluble in alcohol, ketone, ester and other organic solvents and phosphoric acid buffer solution of pH 6.3, but difficult to dissolve in ether, chloroform, benzene and water. Form salt Chemicalbook with potassium and sodium ions and dissolve in water. Gibberellin solid is relatively stable, stored for a long time under dry and closed conditions will not fail; Water solution is unstable, short-term storage at low temperature will not fail, higher temperature decomposition faster; Acidic or weak acidic conditions are more stable, alkaline conditions are unstable.

Plant hormone

Gibberellin is a kind of plant hormones with the alkane ring structure of gibberellin, which can promote plant growth. It exists in both dissociative and conjugated forms. There are at least two or more kinds of GIBberellins in plants, and different gibberellins can be converted to each other. Chemicalbook Leaves, buds, roots and young tissue of immature seeds are the main synthesis sites of GIBberellin. It has physiological effects such as promoting stem elongation, inducing lichen extraction and flowering of long-day plants under short-day conditions, breaking dormancy, promoting fruit setting, parthenogenesis and cell division and differentiation.

use

Highly effective plant growth regulator. Can promote crop growth and development, early maturity, improve quality, increase yield; It can quickly break the dormancy of seeds, tubers and bulbs and promote germination; Can reduce Chemicalbook less bud, flower, boll, fruit loss, increase fruit setting rate or seedless fruit formation. Can be used in rice, wheat, cotton, fruit trees, vegetables and other crops, promote its growth, germination, flowering, fruit
