Development of seedlings of arabica cvs. grafted in Apoata IAC 2258

This study evaluated the development of seedlings of Coffea arabica cvs. grafted in Apoata IAC 2258 (Coffea canephora). The experimental design used was a randomized block with a 7x 3+2 factorial arrangement. Were utilized seven C. arabica cultivars (Obata IAC 1669-20, Acaua, Oeiras MG 6851, Catuca Amarelo 2SL, Topazio MG 1190, IBC Palma II and Para so MG H 419-1), three kinds of seedlings (grafted, self grafted and ungrafted) and two Apoata IAC 2258 rootstocks control (ungrafted and self grafted). There were evaluated the plant height, leaf area, aerial parts dry matter and root system dry matter. The ungrafted seedling showed the best development for all the evaluated characteristics. The effects of ungrafted and self grafted varies depending on the genotype grafted. The IBC Palma II cv. has behavior indifferent to the type of change which is produced for the trait height. There is a difference in behavior of the root system of the rootstock depending on the cultivar used as a graft. The grafts Obata IAC 1669-20, Acaua or Oeiras MG 6851 can be recommend for use in areas infested with nematodes.
