EFFECT OF GRAFTING TECHNIQUES AND CURING PERIOD OF SCION IN JACKFRUIT (Artocarpus heterophyllus Lam.)
Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 3
Abstract
Investigations consisted of two trials viz., effect of grafting methods and curing period of scion on success of graft union and growth of grafts and effect of age of rootstock on success and growth of softwood grafting. Among the three grafting methods under study, epicotyl grafting recorded the highest per cent of graft success (48.08%) as compared to softwood grafting (35.55%) and approach grafting (9.17%). With regard to scion curing, 10 days old cured scion registered significantly the maximum per cent of graft success (37.75%). The interaction effects were significant with the highest success recorded in epicotyl grafting with ten days old cured scion (ET2) (64.00%).The minimum number (17.99) of days taken for bud sprouting was in case of epicotyl grafting, among the various methods tried. Whereas, among the interaction effect, least number of days (17.50) was recorded with epicotyl grafting with ten days old cured scion. Growth parameters like number of leaves, number of buds, number of branches, length and girth of shoot were the maximum in scions cured for ten days. Among the grafting methods and interaction effect, number of leaves, number of branches and length of shoot were maximum in epicotyl grafting with scion cured for ten days. Vigour of grafts expressed in terms of number of buds and girth of shoot were maximum in softwood grafting with ten days old cured scion. The least mortality (32.20%) was recorded in epicotyl grafting with ten days old cured scion.
