Carrot cell suspensions with five different genotypes were tested for esterase relative specific activity in the presence of fungal extracts and toxins. The treatments were as follows: rA: A. dauci (strain FRA017) fungal culture raw extract; rM: uninoculated medium raw extract; aA: A. dauci fungal culture aqueous extract; aM, uninoculated medium aqueous extract; oA: A.dauci fungal culture organic extract; oM: uninoculated medium organic extract; DMSO: DMSO solution at a concentration corresponding to oM, z1, z2 and z3 treatments; z1: 0.025 µM zinniol; z2: 10 µM zinniol; z3: 500 µM zinniol. Correlation coefficients corresponding to significant (α = 0.05) linear regressions are in bold.
