Abstract : The effects of temperature, basal wounding, IBA, leaf presence and duration, on rooting, in a device supplying basal heat to mango hardwood cuttings, are described. Raising the basal temperature from 30° to 35°C almost doubled the % rooting. Rooting at 25° was negligible. Wounding (4 vertical incisions at the base of cuttings) and dipping in IBA (2500 and 5000 p.p.m. in 50% alcohol) increased % rooting. When IBA was applied to both base and sides, 2500 p.p.m. gave better rooting than 5000 p.p.m. Cuttings with leaves rooted slightly better than those without leaves. Rooting was achieved in 88% of cuttings after 4 weeks.
