The object of this research is propagation through green macroexplants derived from the apical, medial and basal segment of the sprig in the variety “I Bardhi Tiranes” (BT). The parts were treated with Indole-3 Butyric Acid (IBA), (1gl¯¹, 3gl¯¹, 5gl¯¹ and Control), mist-propagation. The procedure took place in two phases of the meristematic development; May (active) and December (asleep). The percentage of rooting fluctuated from 6.1 and 68.3%. The concentrations of IBAs 3gl¯¹ were more efficient during the active cambial development; whereas the high concentrations 5gl¯¹, during the phase of low development of the cambium. In May the apical parts rooted at e higher percentage for all the treatments: (1gl¯¹, 3gl¯¹, 5gl¯¹ IBA and Control), compared to the medial and basal parts of the sprig. IBA in high concentrations during the phases of active vegetation has become an inhibitor of rooting. The concentration of 1gl¯¹, had weak reactions and was inefficient. (P=0.05). The olive BT displays the best endogenous predisposition in May. The presence of the leaves has been a stimulating factor for rooting (r²=0.93). The number of roots has increased in parallel with the increase of concentration, (r²=072), whereas the length of roots has not been influenced by the concentrations and the phase of rooting.
