Fig. 1.

Development of B. glumae disease symptoms in rice seedlings (cvF733), at 7 DAI, through two inoculum sources of the pathogen (A) Seed (vacuum inoculation) and (B) Substrate (pathogenic bacteria incorporated into the supporting substrate). Different letters show statistically significant differences between treatments, with each of the variables (stem length, root length and degree of infection), according to the Duncan test, with a level of 95.0% confidence. The graph corresponds to one of at least two repetitions in time, for both infection models, which showed the same trend and statistical differences.
