Gibberellic Acid (GA3)

$8.50

Description

Gibberellic acid was first identified in Japan in 1935, as a metabolic byproduct of the plant pathogen Gibberella fujikuroi (thus the name), which afflicts rice plants; fujikuroi-infected plants develop bakanae (“foolish seedling”), which causes them to grow so much taller than normal that they die from no longer being sturdy enough to support their own weight.

Gibberellins have a number of effects on plant development. They can:

  • stimulate rapid stem and root growth
  • induce mitotic division in the leaves of some plants
  • increase seed germination rate

Gibberellic acid is sometimes used in laboratory and greenhouse settings to trigger germination in seeds that would otherwise remain dormant. GA3 is used to break dormancies in seeds generally requiring cold stratification or light dependent germination.

Info at Wikipedia. GA3 is used to break dormancies in seeds generally requiring cold stratification or light dependent germination.

Our GA3 comes with an information sheet on how best to utilise this product. Concentrations from 500-1000ppm are the most commonly used to stimulate germination.

Approx 50mg GA3 per packet. (this makes 50ml of 1000ppm GA3 or 100ml of 500ppm GA3)
