Figure 5. Correlation between cell suspension reactions to Alternaria dauci raw extracts and whole plant resistance to the A. dauci fungus.
log(AUDPC) data, calculated from visual assessments, are the same than in Table 1. The same genotypes were also tested for esterase activity in the presence of fungal (rA) or uninoculated medium (rM) raw extracts. rA/rM denotes esterase activity variations due to the presence of fungal extracts. A negative correlation coefficient (r = −0.7221, r2 = 0.5071) was noted between rA/rM and log(AUDPC).
