Resumen

ALARCON, Alejandro et al. Effect of arbuscular mycorrhizas and Meloidogyne spp. on tomato (Solanum lycopersicum L.). Rev. Protección Veg. [online]. 2013, vol.28, n.3, pp. 219-223. ISSN 1010-2752.

This study was carried out at the University of Granma (Cuba) from October 2007 to January 2008 in order to determine the effect of arbuscular mycorrhizas and Meloidogyne spp. on tomato (Solanum lycopersicum L.), var. Vyta. Seven treatments of single or combined applications of native and non-native strains(Glomus mosseae (Gerdemann and Trappe), and Glomus sp. (Schenck and Smith), of arbuscular mycorrhizas and an uninoculated control) and two levels of Meloidogine spp. were included in a completely randomized design set up in a factorial arrangement with thirty replicates under semi-controlled conditions. Two kg plastic pots containing a sterile substrate with a mixture of soil and ovine manure in a 3:1 v:v. ratio, as well as a population of Meloidogyne spp. from Granma were used. The gall index and plant growth parameters such as average height (cm), average dry weight (g) and crop yield (kg.plant-1) were evaluated 60 days after nematode inoculation. The data were analyzed by an analysis of variance and the means compared by Duncan's multiple range test (p<0,05). The results indicated that the plant growth parameters evaluated were higher when the native strain was combined with Glomus mosseae and Glomus sp. and the nematode infection level (1,5 eggs.g-1 substrate) was the lowest. However, when the inoculum concentration was increased to 2,5 eggs.g-1 substrate, no significant effect of the arbuscular mycorrhizas on the reduction of the damages produced by Meloidogyne spp. were observed.
