Abstract

In this study, effect of cytokinins and silver nitrate on success of graft union were evaluated in terms of number of days taken for bud sprouting of scion, callus degree, rooting degree, scion/stock ratio and percentage survival of grafts in polyhouse conditions. The treatments include 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. Among the treatments cuttings treated with kinetin 250 ppm followed by BAP 250 ppm recorded beneficial effect on the early union of grafts and subsequent improvement in growth parameters of grafts grown under polyhouse condition.
