The aim of the study was to determine the effects of cytokinins and silver nitrate on success of graft union of Thompson Seedless grape (Vitis vinifera L.) cuttings on Salt Creek. Set of two experiments were conducted in Completely Randomized Design in open condition and another in poly house conditions. The treatments included concentrations of BAP (150 ppm, 250 ppm and 350 ppm), kinetin (150 ppm, 250 ppm and 350 ppm), silver nitrate (50 ppm, 100 ppm and 150 ppm) and control. IBA 2000 ppm was commonly treated for all the basal end of the rootstock cuttings. The treated cuttings were grafted and analyzed for various growth parameters. Among the treatments, cuttings treated with kinetin 250 ppm followed by BAP 250 ppm recorded beneficial effect on the early graft union and subsequent improvement in growth parameters of grafts grown under polyhouse condition compared to open conditions.
