Produção de cafeeiros Coffea arabica L. pés francos autoenxertados e enxertados em apoatã IAC 2258

Abstract: RESUMOVisando obter informações sobre a produção de sete cultivares de C. arábica L. pé franco, auto-enxertados e enxertados no porta enxerto C. canephora Pierre ex Froehn cultivar Apoatã IAC 2258, foi instalado e conduzido este ensaio, em condições de campo isento de nematóides, de janeiro de 2004 a junho de 2006. O delineamento experimental utilizado foi em blocos casualizados, num esquema fatorial (7 x 3) com quatro repetições, sendo sete cultivares de Coffea arabica L. e três tipos de mudas (enxertada, aut… Show more

“…Furthermore, some authors observed that, in an area free of nematodes, coffees grafted on ' Apoatã IAC 2258' were less productive (Dias et al 2009;Paiva et al 2012) and showed lower vegetative development (Oliveira et al 2004;Dias et al 2011) than the same coffee without grafting. Despite some disadvantages, rootstock cultivars Apoatã IAC 2258, in Brazil, and Nemaya, in Central America, have allowed the maintenance of crops in areas infested by root-knot nematodes.…”

“…Esses resultados confirmam a hipótese já citada de estresse provocado pela enxertia. Possivelmente, a diferença detectada se deu em função das variações genéticas das cultivares e morfológicas e fisiológicas do sistema radicular de cada cultivar (TOMAZ et al, 2008;DIAS et al, 2009).…”

“…In nematode-infested areas, nongrafted susceptible genotypes produced up to 55% less than those genotypes grafted on IAC Apoatã 2258 (Barbosa et al, 2014). In a study carried out in an area naturally infested with M. incognita in Paraná, Dias et al (2009) found that the cultivar Iapar 59 grafted on Apoatã 2258 obtained a grain yield 448% higher than the treatment with the nongrafted cultivar Iapar 59. This study demonstrates the efficiency of Apoatã rootstock in maintaining graft production, even in areas infested by the nematode.…”
