Figure 5. Inhibition of growth of P. lycopersici by selected UV-A and UV-C candidate mutants in comparison with their parental T. harzianum, Th12, in dual cultures. PDA containing plates were inoculated both with P. lycopersici and Th12 or the different UV-A and UV-C candidate mutants, 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.
