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
