Effect of the Age of Root-Stock on the Success of Soft-Wood Grafting in Different Cultivars of Mango

Abstract

: An investigation was conducted to study the influence of the age of root-stock on the success and growth parameters of grafts using the method of soft-wood grafting in Amrapali, Mallika, Dashehari, Chausa, Langra and Bombay Green cultivars of mango. The experiment was conducted at Horticulture Garden, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, during 2015-2016. The results of the present study indicated that the scion Langra performed the best for the two graft success parameters (GSPs)—the sprouting time and % graft take success and the two graft growth parameters (GGPs)—the scion-shoot girth and the number of leaves per plant; Chausa for the % graft survival and Bombay Green for the scion-shoot length. Amrapali was observed to perform the worst for the % graft take success, the scion-shoot girth and the number of leaves per plant, while Mallika performed the worst for the sprouting time, the % graft survival and the scion-shoot length. The grafting performed on the root-stock at age six months showed the worst for all the GSPs and GGPs. The grafting done on the root-stock at age two months performed the best for all the GSPs and GGPs, except the scion-shoot girth for which the grafting done on one month old root-stock was found to be the best.
