    Product Description

    Gibberellin A4 is a plant hormone originally isolated from G. fujikuroi that has plant signaling and growth stimulatory activities.1 Gibberellin A4 is found in the micropylar endothelium cells of Arabidopsis maternal seed tissue and triggers suspensor programmed cell death (PCD) in the embryo.2 It increases hypocotyl, but not radicle, growth of cucumber seedlings when used at concentrations ranging from 6-100 µM.3 Gibberellin A4 also increases flowering in apple trees when applied post-flowering in the previous year.4

    WARNING This product is not for human or veterinary use.
