Produção de cafeeiros Coffea Arabica l. pés francos, autoenxertados e enxertados em apoatã IAC 2258

Abstract

Aiming to get information about the production of seven cultivars of coffee trees (Coffea arabica L.), ungrafted, self grafted or grafted on Apoatã IAC 2258 (Coffea canephora Pierre ex Froehn) rootstock, this essay was installed and carried out on a nematode-free-land from January 2004 to June 2006. The experimental outline used was the randomized blocks with a 7 x 3 factorial split-plot arrangement and four replications, as follows: seven Coffea arabica L. cultivars and three types of seedling (grafted, selfgrafted and ungrafted). The results obtained from the first production showed that grafted seedlings yielded less than the self grafted and ungrafted plants, regardless of the cultivar. No significant differences were found between the ungrafted and the self-grafted coffee trees. Coffee trees (Coffea arabica L.) grafted on Coffea canephora Pierre ex Froehn, cultivar Apoatã IAC 2258 are not recommended for nematoid-free land. The Paraiso cultivar was less productive than the other cultivars.
