Abstract
Four cultivars of blackberry (Rubus spp.) were propagated in July under intermittent mist by rooting two-node softwood stem cuttings treated with indole-3-butyric acid (IBA). IBA was applied in either a talc preparation or as a liquid quick dip at 0.1, 0.3 or 0.8% concentrations, with non-treated cuttings as a control.
Differences in root development were evident and were affected by cultivar, IBA concentration, and method of application.
Compared to non-treated cuttings, root development increased on ‘Navaho’ thornless blackberry cuttings treated with 0.3 and 0.8% KIBA quick dip.
Cuttings of ‘Chester’ thornless blackberry treated with 0.1 and 0.8% IBA in talc and 0.3 and 0.8% KIBA quick dip produced better root systems than non-treated cuttings.
Treatment of ‘Cheyenne’ thorny blackberry with 0.3% IBA in talc and 0.8% KIBA quick dip increased rooting compared to non-treated cuttings.
Cuttings of ‘Olallie’ thorny blackberry rooted better than non-treated cuttings with 0.1 and 0.3% IBA in talc and 0.3% KIBA quick dip.
