Abstract
Propagation of Pyrus communis L. rootstock by tissue culture methods using MS medium with different concentrations of growth regulators was examined. Experiments showed that BA and IBA at concentrations of 10 and 1.0 mg / L alternatively were most effective in vegetative multiplication. Different auxins (IAA , IBA) were added to MS medium with different salt strength. Results showed that addition of IAA at 10 mg / L, to MS medium with ¼ salt strength ,was most effective in root formation.This study showed that by using tissue culture methods and suitable growth regulators it is possible to obtain more than 60.000.000 plants from single segment in a year, these plants could be easily transfer to soil and grown in the field
