| Abstract | ||
| This work has been carried out In the Horticultural Research Institute. The stem cuttings were planted (soft and semi- hardwood) under mIst In green house for Mo seasons 2003 and 2004. Cutting treated with 3000 ppm lBA gave the highest rooting percentage, while the lowest was untreated cutting in both seasons. All treatments significantly incrased root number and length per cuttIngs of peer rootstocks (Pyrus betulaefoiia), Bacteria strains for 2hr induced the highest sIgnIcantly root number. Regarding the effect of lBA and bactena strains treatments on average shoot number per cutting. bacteria strains for 2hrs induced the hIghest signIfcant shoot number in both seasons. The highest sIgnIficant rooting percentage resulted from cutting collected in May treated wIth lBA at 3000 ppm Regarding the kind of cuttings, softwood cutting prepared and planted in May to August gave the highest precentage of rooting compard with semi-hardwood cuttings. ThIs res_ult may be due to total soluble sugers,indoles and amino acid were the hIghest contents In softwood cuttings during May. Tne anatomy studies in all treatments shows clearly that advanced development of adventitious roots | ||
