Resumo
Visando obter informações sobre o desenvolvimento de cafeeiros (Coffea arabica L.) enxertados ou não no porta enxerto Apoatã IAC 2258 (Coffea canephora Pierre ex A. Froehner) foi instalado e conduzido esse ensaio em campo isento de nematóides, de janeiro de 2004 a maio de 2005. O delineamento experimental utilizado foi blocos casualizados em esquema fatorial (7 x 3), com parcelas subdivididas no tempo e quatro repetições, sendo sete cultivares de C. arabica e três tipos de mudas (enxertada, auto enxertada e pé franco) e quatro épocas de avaliação. Foram avaliadas altura de planta, número de ramos plagiotrópicos e número de nós nos ramos plagiotrópicos. Pelos resultado conclui-se que a muda enxertada não é superior à muda de pé franco para nenhuma característica avaliada, independentemente da cultivar. Foi observado efeito do estresse causado pela enxertia e efeito porta-enxerto Apoatã.
This study was carried out in nematode-free land, during the period from January 04 to May 05, aimed at obtaining information on the development of coffee trees (Coffea arabica L.) grafted or non-grafted on the rootstock Apoatã IAC 2258 (Coffea canephora Pierre ex A. Froehner). The experimental design used was a randomized block with a (7 x 3) factorial split-plot arrangement and four replications, as follows: seven C. arabica cultivars and three types of seedlings (grafted, self grafted and non-grafted), evaluated in four time periods. The experiments were evaluated for plant height, plagiotropic shoots number and number of nodes on plagiotropic shoots. The results concluded that grafted seedlings were not superior to the non-grafted ones in any of the evaluated characteristics, regardless of the cultivar. But the effects of stress caused by grafting and Apoatã rootstock were observed.
