| Abstract:
Mallet cuttings of peach cv. "Redhaven", consisting of a 2.5 cm segment of stem with a leaf and an axillary bud, were rooted under intermittent mist during the summer. Four propagation dates from July, 21st to September 1st, three IBA concentrations (0, 2500, 5000 ppm) and a wounding practice against a non-wounded control, were arranged in a factorial design. The best rooting (88%) was achieved with cuttings collected on August 5th, wounded and treated with IBA at 2500 ppm. Before this date the maximum rooting percentage was 42%, while after this date no more than 17% rooting was obtained. The wound improved the rooting percentage of up to 42% (from 46% to 88%) in the best conditions. No difference was found between the two concentrations of IBA in non-wounded cuttings, while in the wounded ones the lower level of auxin showed the best results. Roots were already visible after 4 weeks. | |
