Abstract
El uso de plantas injertadas es una técnica usada para el control de Meloidogyne spp. en café, incluye múltiples factores que influyen sobre el comportamiento de la púa y el porta-injerto, también sobre el crecimiento y desarrollo de la planta injertada. En Perú, son pocos los trabajos realizados sobre esta relación, de manera especial el caso del café. Este experimento se realizó con el objetivo de evaluar el comportamiento de nueve cultivares de café: Laurina IAC 870, Catuaí vermelho IAC 144, Catuaí vermelho IAC 99, Catuaí amarelo IAC 86, Caturra amarelo Col. 88 IAC 476, Bourbon vermelho IAC 662, Caturra vermelho IAC 477, <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20 y Limaní, injertados sobre Coffea canephora en presencia y ausencia de Meloidogyne spp. en fase de vivero. Los resultados mostraron que en altura y diámetro de tallo destacó el injerto <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20/Robusta (inoculado), mientras que para número de hojas, el injerto Caturra Vermelho IAC 477/Robusta (inoculado). Al medir la biomasa seca de la parte aérea y radicular, los injertos Laurina IAC 870/Robusta (no inoculado), Caturra Vermelho IAC 477/Robusta (inoculado) y <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20/Robusta (inoculado) tuvieron los valores más altos. Para el índice de Calidad de Dickson (ICD), los injertos Caturra Vermelho IAC 477/Robusta (inoculado) y <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20/Robusta (inoculado) fueron los más destacados. Se concluyó que Caturra Vermelho IAC 477 y <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20 injertados sobre C. canephora fueron los cultivares que mejor respondieron ante la presencia de Meloidogyne spp.
The use of grafted plants is a technique used for the control of Meloidogyne spp. in coffee, which includes múltiple factors that influence the behavior of the barb and the gran holder and also the growth and development of the grafted plant. In Perú, little work has been done to know the relationship between the barb and the graft holder, especially in the case of coffee. This experiment was carried out with the objective of evaluating the behavior of nine coffee cultivars: Laurina IAC 870, Catuaí vermelho IAC 144, Catuaí vermelho IAC 99, Catuaí amarelo IAC 86, Caturra amarelo Col. 88 IAC 476, Bourbon vermelho IAC 662, Caturra vermelho IAC 477, <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20 and Limaní, grafted on Coffea canephora in presence and absence of Meloidogyne spp. in nursery phase. The results showed that the <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20/Robusta graft (inoculated) stood out in height and stem diameter, while for the number of leaves was the Caturra Vermelho IAC 477/Robusta graft (inoculated). When measuring the dry biomass of the aerial and root part, the Laurina IAC 870/Robusta (not inoculated), Caturra Vermelho IAC 477/Robusta (inoculated) and <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20/Robusta (inoculated) grafts had the highest valúes. For the Dickson Quality Index (ICD), the Caturra Vermelho IAC 477/Robusta (inoculated) and <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20/Robusta (inoculated) grafts were the most outstanding. It was concluded that Caturra Vermelho IAC 477 and <img border=0 width=40 height=12 src="../img/a02_figura11.gif">IAC 1669-20 grafted on C. canephora were the cultivars that best responded to the presence of Meloidogyne spp.
