Figure 8. % Inhibition of growth of P. lycopersici by selected protoplast fusion candidate mutants in comparison with their parental T. harzianum strains, in volatile metabolites experiments. A half PDA containing plate inoculated with P. lycopersici was sealed with other half plate inoculated with any of the parental strains or the different protoplast fusion candidate mutants, avoiding physical contact between strains, and incubated at 23ºC during seven days. Experiments were run in triplicates. Results were analyzed using the Tuckey test at 5% significance. Different letters mean significant differences.
