Abstract

The influence of different IBA concentrations on rooting level and rooting quality of wood cuttings on dwarfing rootstock Prunus pumila L. for peaches was investigated in 1996 and 1997. Number of roots, average root length, depth, minimal and maximal diameter of root knot and rooting level were evaluated. Rooting level of basal cuttings was 94.8%, of median cuttings 70.9% and of apical cuttings 49.1%. All of them formed a well developed root system to the 37 cm of soil depth. In average, they developed from 5.2 to 7.0 roots per cutting. Roots were 18.8 to 22.7 cm long. Average values for root knot diameter were between 11.0 and 38.6 cm. All rooted cuttings, except some apical ones, were suitable for the August T-budding four months after planting. The IBA concentration had no influence on rooting success of cuttings. 30 cm long basal and median cuttings are the most suitable ones for propagation of Prunus pumila L.
