Objective: To study the PGPR capacity of Pseudomonas and Chryseobacterium in tomato and to analyze enzymes involved in the plant defense. Materials and methods: Surface sterilized tomato seeds were germinated and transferred to pots with vermiculite: peat. Seedlings were inoculated with native Pseudomonas spp. SF 4c, Pseudomonas spp. SF10b and Chryseobacterium balustinum CECT 5399 to 5 and 20 days. Shoot and root dry weight, shoot diameter and height were measured two weeks after the second inoculation. Results were analyzed by ANOVA at p
