CUTTING PROPAGATION OF EUCALYPTUS FICIFOLIA USING CYTOKININ-INDUCED BASAL TRUNK SHOOTS
Robert L. Mazalewski and Wesley P. Hackett
The cytokinins, PBA and BA were the most effective treatments tested in inducing buds to break in the lignotuber as well as the upper trunk region of Eucalyptus ficifolia. BA at a concentration of 0.8% in water-ethanol (1:1) caused an average of 229 bud breaks per tree. Stem cuttings taken from the PBA-induced shoots exhibited a greater propensity to the root when taken from the area of the lignotuber than when taken from higher on the trunk. Furthermore, cuttings from basal parts of shoots, originating from the lignotuber, rooted better than cuttings taken from the apical portion of these shoots.
