The present investigation was carried out in order to standardize the optimum IBA concentration for vegetative propagation of pear rootstocks Quince-C and BA-29 with reference to vegetative growth and multiplication rate, they were given different concentration of IBA. The treatment with IBA significantly influenced the parameters under study. The IBA treatment @ 1000 ppm was found to be the best in terms of most of the vegetative growth parameters and multiplication rate. The highest multiplication rate was achieved on Quince-C treated with 1000 ppm IBA. Study concluded that IBA treatments significantly influenced vegetative growth and multiplication rate in stem cuttings of pear rootstocks.
