The aim of the present work was to evaluate the mycelial growth and fruiting vigor of Dothichiza populea Sacc. et Br. under various temperatures, pH values, and light regimes. Effect of temperature on the fungus growth was examined by growing isolates in polythermostat at 5 deg C to 30 deg C. The best mycelial growth occurred at 20 deg C, while at 30 deg C it was inhibited. Fruiting of the fungus was not observed at 5 deg C, 25 deg C, and 30 deg C. However, the best fruiting of the isolates appeared at 20 deg C. The influence of different pH of the cultivation medium (3.5-10) on the fungus isolates growth was also evaluated. Optimal pH for the fungus growth ranged between 6 and 8, while formation of reproductive organs occurred at all pH values. The influence of two light regimes (light/dark regime and continuous dark) on the fungus growth was also studied. Obtained results showed tha mycelial growth and fruiting of the fungus were considerably better under the liht/dark regime.
