Figure 3. Growth of protoplast fusion products at 15ºC in comparison to their parental native Trichoderma. PDA containing plates were inoculated independently with each parental strain and each protoplast fusion product and incubated at 15ºC during seven days. Experiments were run in triplicates. Results (radial growth) were analyzed using the Tuckey test at 5% significance. Different letters mean significant differences.
