The in vitro rooting ability of 'OHxF 333 pear rootstock' (Pyrus communis L.) was investigated using indolebutyric acid (IBA) (0, 0.5 and 1.0 mgL-1), putrescine (160 mgL-1) and 4 different rooting procedures: the shoots taken from a multiplication medium (A) were transferred to an IBA- and putrescine-containing medium for 35 days; (B) were placed on an IBA- and putrescine-containing medium for 10 days, after which the shoots were transferred to an auxin- and putrescine-free medium for 25 days; (C) were placed on a hormone-free medium for 15 days, after which the shoots were transferred to an IBA- and putrescine-containing medium for 35 days; and (D) were placed on a hormone-free medium for 15 days, after which the shoots were transferred to an IBA- and putrescine-containing medium for 10 days and then transferred to a hormone-free medium for 25 days. Among the various rooting procedures, procedure A gave the highest rooting percentage (49.50%), number of roots (4.09) and length of roots (2.26 cm). The best results for rooting rate (86.86%) and number of roots (10.36) were obtained from the interaction between procedure A and the addition of 1.0 mgL-1 IBA. The elongation phase used in procedures C and D did not have a superior effect on the rooting rate. Generally, putrescine alone produced a lower rooting rate, number of roots and root length than IBA in all rooting procedures.
