In order to evaluate the rooting ability of semi-hardwood cuttings of some olive (Olea europaea L.) cultivars under mist condition, an experiment was conducted in two years (1999 and 2000) at the Tarom Olive Research Station in Zanjan Agricultural Research Center. A completely randomized design (CRD) with three replications and 21 cultivars were used. Analysis of variance showed significant differences among cultivars for rooting percentage and number of roots per cutting. Date of the cutting affected rooting ability. ʹMahzam-Abousatlʹ, ʹMosabiʹ, ʹBaladyʹ and ʹKaviʹ cultivars were easy-to-root cultivars with 88.5, 86.0, 80.8 and 79.3 rooting percentage, respectively. ʹKalamataʹ and ʹDaneʹ cultivars had the least rooting percentage with 34.67 and 42.33%, respectively. ʹBaladyʹ, ʹMissionʹ, ʹMahzam-Abousatlʹ, ʹCipressinoʹ, ʹFujiʹ and ʹManzanilloʹ were better than other cultivars with 16.8, 16.1, 15.3, 15.14 and 13.3 mean number of roots per cutting, respectively. ʹDaneʹ, ʹKalamataʹ, ʹMastoidisʹ, ʹMari-e-Gorganʹ and ʹKonservoliaʹ had the least rooting ability with 5.7, 7.1, 7.2, 7.2 and 7.5 mean roots number per cutting, respectively.
