Application Notes
Gibberellins are known to promote shoot (internode) elongation and break certain dormancies in seeds. They also can induce flowering in some plant species.2
In a study of potato tuberization, potato cultures treated with 0.01 to 0.03 ÁM of GA4+7 produced normal shaped tubers, while in the same study, higher concentrations ranging from 0.1 to 0.3 ÁM produced abnormal shaped tubers.3 Variations of GA4+7 concentrations have also been observed for tobacco callus. GA concentrations of 0.01-5.0 mg/L have been shown to promote shoot development in tobacco callus, while higher concentrations of 5.0 mg/L to 10 mg/L inhibited shoot production.4
PhytoTechnology Laboratories« also carries Gibberellic Acid Solution at 13 mg/mL (Prod. No. G362), Gibberellic Acid Solution at 1 mg/mL (Prod. No. G198), and Gibberellic Acid powder (Prod. No. G500).
Please Note: Gibberellins can be co-autoclaved with media components; however, some loss of activity may occur.While PhytoTechnology LaboratoriesT tests each lot of this product with two or more plant cell/ tissue culture lines,it is the sole responsibility of the purchaser to determine the appropriateness of this product for the specific plants that are being cultured and applications that are being used.
