THE EFFECTS OF THE DIFFERENT DOSES OF IBA (INDOL BUTRIC ACID) ON THE ROOTING PERFORMANCES IN THE REPRODUCTION OF “GEMLIK” AND “DOMAT” OLIVE TREES BY USING THE GREEN TWIG PROCEDURE IN THE ECOLOGY OF ÇUKUROVA REGION

The effects of the different doses (0, 2000, 4000 and 6000 ppm) of IBA (Indol Butric Acid) on the rooting performances in the reproduction of “Gemlik” and “Domat” olive trees by using the green twig procedure in the ecology of Çukurova region were investigated. The research was conducted in the research area of the Agricultural Faculty at Çukurova University. According to the obtained results, while rooting was not observed in “Domat” olive twigs, “Gemlik” olive twigs yielded better results in the 4000 and 6000 ppm of IBA procedures than those in the control group. Moreover, the conditions of the species of the olive trees, the application period and the dose of the hormone used, the time the twigs were collected, and the condition of the misting unit were also found to be effective in the rooting of the olive twigs
