Effect of IBA on Vegetative Growth and Multiplication Rate in Stem Cuttings of Pear Rootstocks

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.
