The vegetative propagation of Japanese apricot (Prunus mume), for use as rootstocks for Prunus sp., was investigated in Sao Paulo, Brazil, during 1999. Herbaceous cuttings (12 cm long) from clones 02, 05, 10 and 15 were treated with indolbutyric acid [IBA] at 2000 mg/litre for 5 s. Significant differences were found between clones for percentage rooting, with clone 15 having greater rooting than clone 02 (93.75 and 78.13%, respectively). There was no significant difference between clones in relation to callus formation, roots per cutting, length of root or percentage of sprouted cuttings. IBA increased rooting of cuttings, favoured emission of adventitious roots and increased root length.
