Abstract

Experiment was carried out in plastic house that belong to the Red Rose Nursery / Dohuk government in autumn season between 1st Oct 2018, to 30th May 2019, to discuss the effect of media ( peat moss, sand and peat moss+ sand), & IBA concentrations (0, 4000, 6000, 8000) mg.l-1 on rooting might of Semi-hardwood cuttings of photinia (Photinia x fraseri) plant. Results indicate that the highest rooting percentage (50.88) %, plant high (19.17) cm, vegetative fresh weight (9.10) gm and vegetative dry weight (4.09) gm was recorded in cutting that planted in peat moss media which significantly superior than other media. in the other hand the 6000 & 8000 mg.l-1  of IBA caused increased in rooting percentage reached 50.56% and 51.78% respectively , vegetative fresh and dry weight also significantly increase when applied to 4000 and 6000 mg.l-1 of IBA they reached to 8.87 gm, 3.82 gm compared with 2.62gm for control.  In addition, fresh and dry root weight significantly increased with IBA increase from 4000 to 6000 mg. l-1, the highest length of plant is significantly increased reaching 34.11 for 6000-mg. l -1. The interaction between media and IBA concentrations cased increased significantly in all parameters and the highest rooting percentage (73.33) %, plant high (43.33) cm, leaf number (24.00) leaves were for peat moss media and 600 mg. l-1
