Abstract
Apple Malus domestica is a woody plant belonging to the family Rosaceae. Vegetative or clonal propagation is the most important propagation method used for the commercial production of many horticultural crops. The rooting may be increased by the use of growth regulators such as IBA, NAA and different rooting media. Intermittent mist is often used on cuttings because it reduces the temperature of the leaves, lowers respiration, and increases relative humidity around the leaf surface. Factors such as cultivar and age of the source tree; the collection date, length, diameter and degree of hardening of the cuttings; injury and heat treatments of the cuttings and the treatment concentrations of auxin-like compounds. The maximum graft height, scion diameter, rootstock diameter, number of leaves per graft, root length and root diameter were observed in the rootstock and scion combination of Vance Delicious and M-793. Rooting hormones, planting time, maturity of the stock plants and propagation environment might be among the important factors affecting the rooting of stem cuttings.
