Effect of graft union under different growing conditions in jackfruit (Artocarpus heterophyllus L.) Var. Palur-1

Abstract

An experiment was conducted during 2016–17 at Horticultural College and Research Institute, Periyakulam for determining the suitable condition for graft union and success in jack fruit softwood grafts. Experiment was laid out on factorial completely randomized design (FCRD) with three replications. Growth parameters like days taken for graft union, graft success (%), days taken for sprouting, number of sprouts, length of sprouts (cm), plant height (cm), girth of rootstock (cm), girth of scion (cm), number of leaves, leaf length (cm), breadth of leaf (cm), leaf area (cm2), graft survival (%) at 30, 60 and 90 days after grafting were recorded. On comparing the effect of propagation structures namely mist chamber and shade net, mist chamber conditions gave considerable improvement in growth parameters of softwood grafts.
