Evaluate the effect of different concentrations of IBA and type of substrates on rooting cuttings of olive varieties Conservalia

In order to determine the most appropriate medium as well as the best concentration of Indole butyric acid (IBA) for rooting cuttings of olive varieties in terms of greenhouse Conservalia was done in 2016. This experiment was conducted in a completely randomized factorial design. To perform the study, three perlite medium (control), sand perlite and perlite Coco peat also the concentrations of 0, 1000 and 2000 ppm IBA hormone was used. The traits rooting percentage, number of main and lateral roots, length of roots, root length, fresh weight and root dry weight, fresh weight and dry weight of cuttings and chlorophyll a and b were studied. The results of analysis of variance showed that the majority of traits for hormonal treatment and three traits (rooting percentage, number and weight of root cuttings) for the treatment medium at 1% and 5% probability level was significant. Survey results show that perlite sand medium compared to other medium as well as the concentration of 2000 had the highest percentage of rooting. According to the results, rooting percentage, number of roots, number of lateral roots, root length, root fresh weight, dry weight of cuttings in culture medium and hormone IBA interaction was significant. Overall, in this study the best treatment sand perlite medium at a concentration of 2000 ppm IBA hormone for rooting cuttings roots are causing Conservalia olive varieties.
