TOMAZ, Marcelo Antonio et al. Rootstocks affecting the growth and yeld of Coffea Arabica L.. Rev. de Ciências Agrárias [online]. 2011, vol.34, n.1, pp.229-234. ISSN 0871-018X.

The effect of rootstocks on vegetative growth and yield of coffee plants (C. arabica) were evaluated under field condition at Paulo Cândio, Minas Gerais State, Brazil. It was tested four genotypes of C. arabica as grafts the varieties Catuaí Vermelho IAC 15 and Oeiras MG 6851 and the progenies H 419-10-3-1-5, H 514- 5-5-3 and three genotypes of C. canephora as rootstocks: Apoatã LC 2258, Conillon Muriaé-1 and recombination among clones of the variety Robustão Capixaba (EMCAPA 8141) and one genotype of C. arabica L.: Mundo Novo IAC 376-4. As a control it was wed non-grafted plants. Based on the results it could be concluded that plant development may was affected by grafting when non-grafted plants and graft/ rootstock combinations are compared. The grafting combinations Catuaí 15/Conilon, Oeiras/Apoatã, Oeiras/EMCAPA and H419/EMCAPA of 6 year, promoted increase in coffee yield, when compared to the respective non-grafted plant.
