CLONAL PROPAGATION OF OLIVE (OLEA EUROPEAE) THROUGH SEMI- HARDWOOD CUTTINGS USING IBA UNDER SHADED POLYETHYLENE TUNNELS (SPTS)

The most effective rooting hormone (IBA) concentration was determined by studies on the clonal propagation of olive semi-hardwood cuttings. A semi-hardwood cutting experiment was carried out on two different olive cultivars BARI zaitoon-1 and BARI zaitoon-2 cuttings with 0, 2500, 3500 and 4500 ppm IBA solutions planted in the same rooting media (sand). Studies have shown that these two varieties have great potential for proliferation through semi-hardwood cuttings. The cuttings were grown under SPTs for 90 days to assess rooting ability and shooting capability. The sprouting percentage, number of roots, root length, shoot length and survival percentage was the highest in cuttings treated with 3500 ppm IBA concentration, while cuttings without IBA treatment have the lowest results. Overall, 3500 ppm IBA treatment performed better than other treatments. The experimental results showed that semi-hardwood cuttings treated with auxin have potential for clonal propagation in simple and economical shaded polyethylene tunnels.
