AbstractThe purpose of this study is to investigate the effect of two kinds of cutting (hardwood and semi-hardwood) and five concentrations of auxins ( 0). (1000 mg.l-1 IBA + 1000 mg.l-1 NAA) . (2000 mg.l-1 IBA + 2000 mg.l-1 NAA). (4000 mg.l-1 NAA). and (4000 mg.l-1 IBA) on improvement of rooting percentage and rooting number and vegetative growth of fig cvs. "Aswad Dyalla and White Adriatic" . The experiment was factorial design in C.R.D . with 3 replicates and 12 cutting of each treatment. The most important results showed that hardwood cuttings were significantly superior on semi-hardwood cutting in all the parameters. except rooting percentage and shoots number. All auxins concentrations significantly increased all cuttings parameters in comparison with untreated cuttings. Also "Aswad Dyalla" cv. superior with " White Adriatic". The highest rooting percentage 100% obtained from semi-hardwood cuttings of "Aswad Dyalla" cv. treated with 2000 mg.l-1 IBA + 2000 mg.l-1 NAA or 4000 mg.l-1 IBA. or hardwood cuttings treated with 1000 mg.l-1 IBA + 1000 mg.l-1 NAA. or hardwood cuttings of "White Adriatic" cv. treated with 1000 mg.l-1 IBA + 1000 mg.l-1 NAA. while the highest roots number obtained from semi-hardwood cuttings of "Aswad Dyalla" cv. treated with 1000 mg.l-1 IBA + 1000 mg.l-1 NAA and the interaction between "White Adriatic" hardwood cutting treated with 4000 mg.l-1 NAA. which was significantly superior with most interactions.
