OLIVEIRA, Adelson Francisco de et al. Rootings of semi-woody cuttings of olive tree under effects of collection time, substrate, and concentrations of indol-3-butiric acid (IBA). Ciênc. agrotec. [online]. 2003, vol.27, n.1, pp.117-125. ISSN 1413-7054.  https://doi.org/10.1590/S1413-70542003000100014.

Aiming to evaluate the rooting of semi-woody cuttings of olive tree (Olea europaea L.) under effect of combinations of different times, substrates, and concentrations of indol-3-butiric acid (IBA), two experiments, under greenhouse conditions, were carried out on the EPAMIG experimental farm at Maria da Fé, State of Minas Gerais, Brazil. The cuttings were collected from the cultivar 'Ascolano 315', on the same day of the experiment installation, March 2nd, 2000 and April 27th, 2000. The experimental design used in the two experiments was randomized blocks in 4 × 4 factorial scheme with four substrates (sand, vermiculite, sand/earth 1/1, and earth) and four concentrations of IBA (0, 1000, 3000, and 5000 mg L-1), with four replicates. The results indicate rooting of this species is possible in rustic facilities, obtaining 48% of rooting for the substrate sand/earth 1:1 (v/v, and 44% when treated with IBA at the concentration of 3000 mg L-1, for cuttings collected on February 9th, 2000.
