Özet
The effects of various NAA concentrations and applications of SA with IBA in different ways were tested in leafy cuttings of very difficult to root 'Domat' olive. Cuttings were collected from bearing (mature) trees and rooted under mist. Cuttings had the highest rooting rate of 63.3% with routine 5 g l-1 IBA treatment. Primary root number (4.1), root length (32.10 mm), root thickness (1.10 mm), root fresh/dry weights and VR score were at the highest level with the same treatment. Untreated cuttings entirely failed to root. NAA treatments produced less rooted cuttings than those treated with IBA alone. Cuttings receiving 3 g l-1 NAA gave 36.6% rooting. Free applications of SA did not give rise to any root formation. No synergistic effect was detected caused by simultaneous applications of 5 g.l-1 IBA combined with SA concentrations ranged between 2.5-10 g.l-1. In both pre applications and post applications of SA strongly inhibited the rooting of cuttings compared to simultaneous applications of both substances. Interval of 15 days between auxin and SA application might be too long to exhibit the promised phase dependent effect of SA on root formation was concluded.
