Increased root initiation in cuttings of Eucalyptus nitens by delayed auxin application

Root initiation in cuttings of Eucalyptus nitens (Deane & Maiden) Maiden. was stimulated by application of auxin dips in the form of 20 mg/l solution administered for 48 h. The greatest stimulation of rooting was obtained when auxin was applied to the cuttings at least four weeks after the cuttings were first collected and set on a mist-bed.
