This study was conducted in North Sinai Research Station at EI-Sheikh Zuwayid, Desert Research Center (D.R.C.) during the 2006, and 2007 seasons. It aimed at evaluating the effect of different propagation techniques and collection dates of cuttings on rooting ability of five recently introduced olive cultivars. Leafy subterminal cuttings of olive cultivars Chiperssino, Tanche, Jabaa, Conservollia and Itrana were prepared during March, June, September and December, treated with IBA at 4000 ppm and rooted using intermittent mist, vapor pressure deficit (V.P.D.) and wooden boxes propagation techniques. A wide variation in rooting ability of the studied cultivars was found. Cuttings of olive cv. Cheperssino had a significantly superior rooting percentage, whereas, cuttings of olive cv. Itrana gave the lowest significant percentage. Moreover, cuttings sown in wooden boxes exhibited the highest significant rooting percentage in comparison to V.P.D and mist propagation techniques. In addition, June collection date showed the highest significant rooting percentage, number of roots and root length under V.P.D. and mist propagation techniques. Meanwhile, the wooden boxes propagation technique significantly resulted in the highest rooting percentage during March collection date.
