S ummary A growth inhibiting substance has been extracted from mature tissues of Eucalyptus obliqua in which apical dominance occurs, but is absent in juvenile tissues of very young seedlings which show weak apical dominance. Sprouting from lignotubers in decapitated E. obliqua seedlings is correlated with a reduction in the level of inhibitory properties. Reapplied inhibitory substance, but not abscisic acid, reduced sprouting. The inhibitory substance has been partially purified and some of its properties tested, suggesting that it is not abscisic acid.
