Desenvolvimento de mudas de cultivares de café arábica enxertadas sobre Apoatã IAC 2258

Abstract

This study evaluated the development of seedlings of Coffea arabica cvs. grafted in Apoatã 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 (Obatã IAC 1669-20, Acauã, Oeiras MG 6851, Catucaí Amarelo 2SL, Topázio MG 1190, IBC Palma II and Paraíso MG H 419-1), three kinds of seedlings (grafted, self grafted and ungrafted) and two Apoatã 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 Obatã IAC 1669-20, Acauã or Oeiras MG 6851 can be recommend for use in areas infested with nematodes.
