| Abstract (English): |
This study aimed to evaluate the reaction of six grapevine rootstocks (MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4, Salt creek) and two cultivars (Quebranta and Torontel) to three species of the root-knot nematode (Meloidogyne incognita, M. arenaria and M.hapla). The experiment was performed as a completely randomized design with an 8 x 3 factorial scheme and six replicates per treatment. The experimental unit in each replicate comprised a grapevine cutting planted in 3 kg bags with sterilized soil. Cuttings were inoculated with 5000 eggs + juveniles (J2) of M. incognita, M. arenaria and M. hapla. Six months after inoculation, plants were removed from the bags, and the reaction was determined by evaluating the number of galls (NG), number of nematodes per gram of root (NNGR), and reproduction factor (RF). The evaluated rootstocks, MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4 and Salt Creek, were resistant to M. incognita, M. arenaria and M. hapla, except for Salt creek, which was susceptible to the latter. The Quebranta and Torontel cultivars were susceptible to the Meloidogyne species under study. [ABSTRACT FROM AUTHOR] |

El presente estudio se realizó para evaluar la reacción de seis portainjertos (MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4, Salt creek) y dos cultivares de vid (Quebranta y Torontel) a tres especies del nematodo de la agalla (Meloidogyne incognita, M. arenaria and M. hapla). El experimento se realizó con un diseño completamente al azar con un esquema factorial de 8 x 3 y seis repeticiones por tratamiento. La unidad experimental en cada repetición estuvo constituida por una estaca de vid plantada en bolsas de 3 kg con sustrato esterilizado. Se inocularon las estacas con 5000 huevos + juveniles (J2) de M. incognita, M. arenaria y M. hapla. Seis meses después de la inoculación, las plantas se extrajeron de las bolsas y la reacción se determinó evaluando el número de agallas (NA), el número de nematodos por gramo de raíz (NNGR) y el factor de reproducción (FR). Los portainjertos evaluados, MGT 101-14, Ritcher 110, Paulsen 1103, K 5BB, SO4 y Salt Creek, fueron resistentes a M. incognita, M. arenaria y M. hapla, excepto Salt creek, que fue susceptible a este último. Los cultivares Quebranta y Torontel fueron susceptibles a las especies de Meloidogyne en estudio. [ABSTRACT FROM AUTHOR] |
