| Abstract:
Olive plants, cv. Kalamon, pruned to form stool beds, were used as mother plants for tender, juvenile layers. The effects of etiolation, auxin (IBA) application, wire-tightening, wounding, position of application and the season were studied on the rooting capacity of the layers, with an improved method of mound-layering. Etiolation of field-grown plants for 50 days before the auxin application, combined with 3% IBA, increased the number of roots per layer. Tender layers of pot-grown plants were treated, in winter or summer, with 3% IBA at their base or at the second nod, and with combinations of wire-tightening and wounding. Direct application at the base of the shoot resulted in the earliest rooting response and the highest rooting percentage and number and fresh weight of roots, in both seasons. Application of IBA (0, 0.5, 1, 2, 3%) directly at the base of tender layers revealed a linear correlation between IBA concentration and rooting percentages, number and fresh weight of roots. The new plants, due to their rich root system grew fast and reached saleable size within six months. | |
