Contents of the phytohormone SA in L er and Bur, mock-inoculated and inoculated, at different developmental stages. I: early-flowering stage, II: mid-flowering stage, III: beginning of silique maturity. N = 8. Significance levels refer to differences of means between the ecotypes within one treatment (mock- and V. longisporum-inoculated, respectively) as determined by t-tests. Differences between mock- and V. longisporum-inoculated plants were always significant. V43 = V. longisporum isolate 43.
