Gibba

Gibberellic Acid (GA) is a systemic plant growth regulator that primarily influences above-ground plant parts by stimulating cell elongation, division, and differentiation. Widely used in horticulture, GA regulates key processes such as stem elongation, leaf expansion, flowering, and fruit development. Its targeted action helps improve plant architecture, increase fruit size, and enhance crop uniformity, making it a valuable tool for managing growth and optimising yield. GA also stimulates the production of winter-dormant, grass-dominant pastures for high-intensity grazing, such as sheep lambing paddocks and dairy pasture.

Profile

First registered as a plant growth regulator in 1962, GA stimulates plant growth by promoting cell elongation and division. It binds to GA receptors in plant cells, activating genes that produce enzymes and proteins responsible for cell wall loosening, expansion, and division. GA also supports berry thinning, bunch elongation, dormancy breaking, flowering, fruit growth, and mobilization of stored nutrients in seeds and tubers.

Key Features & Benefits

Natural plant hormone: Mimics endogenous gibberellins to regulate plant growth effectively
Promotes cell elongation and division: Enhances stem elongation, leaf expansion, and overall plant vigor
Improves fruit quality and yield: Supports berry thinning, bunch elongation, larger fruit size, and uniform development
Stimulates flowering and breaks dormancy: Encourages timely flowering and uniform sprouting in seeds and tubers
Versatile crop application: Suitable for grapes, fruit crops, ornamentals, and seed/tuber propagation, optimizing growth, quality, and productivity
