Standardisation of grafting techniques in African marigold (Tagetes erecta L.)
Keywords:
African marigold, Cleft grafting, Splice grafting, Hole insertion graftingAbstract
A study was conducted during 2017-18 at the Department of Floriculture and Landscaping, College of Horticulture, Vellanikkara, Thrissur to standardise the grafting method, age of rootstock and age of scion in African marigold (Tagetes erecta L.). The experiment was laid out in Completely Randomised Design with 2 replications and 27 treatments, which comprised of different grafting methods (cleft, splice and hole insertion) using various stages of rootstock (4, 5, 6 and 7 weeks after sowing) and scion (3, 4 and 5 weeks after sowing). Among different treatments followed, cleft grafting 4 week old scion onto 6 week old rootstock was found to be superior in terms of graft survival. There was no survival when grafting was done on four week old rootstock, irrespective of the grafting methods. It was also observed that hole insertion method was not successful, irrespective of the age of root stock and scion.References
