Figure 2. Growth of UV-A (a) and UV-C (b) new strains at 15ºC in relation to their corresponding parental native Trichoderma. PDA containing plates were inoculated independently with each strain and incubated at 15ºC during seven days. Experiments were run in triplicates. Results (radial growth) were analysed using the Tuckey test at 5% significance. Different letters mean significant differences. *abnormal growth and sporulation.
