Resumen

© 2016 Universidad Autonoma de Tlaxcala. All right reserved. Methylobacterium is a persistent colonizer of plant leaf surfaces, and Glomus is a arbuscular mycorrhiza associated with almost 90% of the terrestrial plants. It was assessed the synergistic activity of the consortium Methylobacterium-Glomus in plant growth development, seed germination and Induction of Defense Enzymes against Fusarium sp in Lycopersicum esculentum var verome. Seeds were inoculated with Methylobacterium sp and Glomus sp and seed germination was evaluated in terms of morphometric measurements, seedling growth, rate of germination (RG), and seedling vigor index (SVI). To evaluate the induced systemic resistance, it was assessed the presence of the pathogenesis related proteins (PRP) in tomato plants developed from seeds inoculated with Methylobacterium and the consortium Methylobacterium-Glomus. The consortium and Methylobacterium inoculation promoted seed germination and plant growth, increased plant height, plant biomass and side shoots were observed. The peroxidase activity is significant different statistically in the presence of the consortium in reference to the other treatments, however, the other enzymes and phenolic compounds, there was no difference between the treatments, but there was in reference to the control without microorganisms.
