The hormone quantification of SA, ABA and JA did not show significant differences between treatments on day 0 (previous to inoculation of the leaves with the pathogen) (Table 6). The SA concentration of infected leaves of plants grown in compost CM significantly increased on day 1 post-inoculation, and was higher than in plants grown in P and P + T34. On days 3 and 5 post-inoculation, the SA levels of CM still were higher than in the rest of treatments. On day 5, leaves of plantsgrown in P and P + T34decreased similarlyor below the levels of day 0.
