Effect of rootstock variety, cut surface and grafting time on graft success of Mangifera indica L. var. wirasangka

Abstract

Mangifera indica L. var. wirasangka is a local variety of Tegal Regency. It is rarely planted due to the limited number of seedling. The research aimed to develop an effective shoot grafting method. The study was conducted experimentally with a factorial completely randomized design of three factors. The first factor was mango variety for rootstock (keong mango and santok mango). The second factor was cut surface shape (cleft, splice, and side-veneer graft). The third was time of grafting (morning and afternoon). The observed data were the number of shoots, the shoot length, the number of leaves, and the percentage of success graft. Data were analysed using Analyses of Variance and LSD test. The results showed that variety of rootstock did not affect the success graft, but affected the growth of scion. The cut surface affected the success graft and growth of scion. In contrast, grafting time did not affect the success graft and growth of scion. Cleft graft were most effective for grafting of wirasangka mango. Based on the result it was recommended that the success shoot grafting of wirasangka mango can use keong and santok varieties, grafted using the cleft surface and done in the morning or afternoon.
