Abstract
The effect of wounding applied to the bases of herbaceous cuttings on the rooting of Japanese apricot (Clones 02, 05, 10 and 15) was studied in an experiment conducted at Jaboticabal, Sao Paulo, Brazil. Wounding was performed by making opposite incisions (+or-3 cm long and +or-1 mm deep) at the base of 50% of the cuttings, slightly removing the phloem tissue with a knife. Control cuttings were left undamaged. All cuttings were treated with IBA at 2000 mg/litre for 5 sec. Differences between the clones were observed concerning rooting percentage, dead cuttings and number and length of roots, with Clone 10 and 15 being superior to the other clones. Wounding increase the number of roots, but the results were not considered sufficiently beneficial to make the treatment worthwhile.
