Abstract Banding with Velcro™ of new shoot growth in moderately difficult-to-root apple rootstock MM.106 (Malus domestica Borkh.) for 7 days prior to taking cuttings, and treatment of cuttings with 500 to 2000 ppm indolebutyric acid (IBA) increased both percent rooting and root number. Banding, however, did not influence the rooting of easy-to-root Franklinia alatamaha Marsh. IBA at 0 to 1000 ppm induced a logarithmic increase in percent rooting of cuttings of MM.106 and root number of cuttings of Franklinia; but, higher levels of IBA reduced both. Banding prevented the rooting inhibition found at high concentrations of IBA in cuttings of MM.106, while simultaneously stimulating lateral budbreak and greater root number. Stem banding improved the establishment of cuttings treated with 1000 ppm and 2000 ppm IBA. Without banding, establishment of these cuttings was markedly decreased.

Leaf Boron

Redistribution of boron (B) within apple trees (Malus domestica Borkh.) as a result of leaf B application was examined. The experiments were canied out in a greenhouse on M.26 apple rootstock and in field conditions on five-year-old 'Elstar' and 'Szampion' apple trees grafted on M.26 rootstock. Boron was applied in a form of boric acid solution. It was found that leaf B application resulted in movement of B to leaves, flowers and apple fiuits untreated with B. These results clearly showed that B was retranslocated within apple tree. The retranslocation of B within apple trees took place when leaf B applications were done both in summer and autumn. Additionally, it was observed that B from leaf application had paiticularly high ability of movement within plant at insufficient B content (0,2μM) in solution. Generally, these data indicated that B within apple trees was transported in phloem, however mechanism of this phenomenon has not been well known yet. Thus, leaf B application of apple trees can be more successful treatment in reduction of B deficiency in plants compared to soil B application.

Root Suckers

The dwarfing apple rootstock Ottawa 3 (O.3) produces trees slightly too large for high density plantings on fertile soils, but it is more cold hardy and better anchored than Malling 9. Our objective was to reduce the vigour of trees on O.3 by budding scions higher or planting the trees more shallowly. Summerland McIntosh was budded at 15 cm onto O.3 and planted such that 6 to 14 cm of the rootstock shank was above ground. Planting depth did not affect tree size, yield or yield efficiency. Increasing budding height from 5 to 25 cm increased vigour control, yield efficiency and the production of root suckers on O.3. Higher budding may be an effective way to reduce the vigour of trees on O.3 in areas where the greater root suckering is not a fireblight hazard. Key words: Malus domestica Borkh., dwarfing rootstock
