* Paper presented in National Dialague on “Sustaining the Productivity of Grapes Under Adverse Situations” organised by National Research Centre on Grapes, held at Pune between 8th to 9th 1999.
The present investigation was undertaken to study the effect of IBA and number of internodes on rooting of stem cuttings of grape root stocks. It was foound that the rootstock 1613-C did not require any chemical treatment for stimulating the root formation while Dogridge and Salt creek cuttings with five internodes were treated with 1500 ppm IAB for better sprouting percentage of 86.60 and 80.00 respectively. The significant results for root growth parameter of rootstocks were obtained at higher concentration of IBA.
