Figure 6. Correlations between cell suspension reactions to Alternaria dauci raw extracts, organic extracts and low zinniol concentrations.
Five carrot genotypes were tested for their metabolic activity when A. dauci raw (rA) or organic (oA) extract was added to the plant culture medium. The same experiments were conducted while adding uninoculated medium raw (rM) or organic (oM) extract and 0.025 µM zinniol to DMSO (z1) or DMSO. rA/rM denotes plant cell esterase activity variations due to the presence of fungal raw extracts, oA/oM denotes plant cell esterase activity variations due to the presence of fungal organic extracts, and z1/DMSO denotes plant cell esterase activity variations due to the presence of 0.025 µM zinniol in the medium. A: correlation plots of rA/rM, oA/oM and z1/DMSO by pairs. Bars represent standard errors. The three paired correlated activity indices presented here correspond to the most significant r2 values (see Table 4). B: 3D correlation plot of rA/rM, oA/oM and z1/DMSO.
