Figure 4. Growth of UV-A new strains at pH 8.0 (a) and of protoplast fusion products at pH 7.5 (b) in comparison to their parental native Trichoderma. PDA containing plates were inoculated independently with each parental strain, UV-A new strains and protoplast fusion products and incubated at 20ºC during seven days. Experiments were run in triplicates. Results (colony area) were analyzed using the Tuckey test at 5% significance. Different letters mean significant differences.
