title: Occurrence and bioassay responses of G : A plant growth regulator in Eucalyptus and other Myrtaceae.
abstract: A growth regulator (G) occurs at high concentrations in adult leaves of E. grandis Maiden. Low concentrations of G are present in juvenile leaves of this species and also in adult leaves of some other Myrtaceae. Low concentrations of G (5×10(-6) and 10(-5) M) promote rooting in mung-bean cuttings and elongation in Avena coleoptile sections; high concentrations (5×10(-4) M) inhibit. These and other bioassay results indicate that G may have auxin-like activity.
