The mycelial expansion rate of P. expansum was measured on
PDA plate as follows. A 5 mm diameter plug of mycelial agar was
placed on the center of a 9 cm diameter petri dish containing 25 mL
PDA supplemented with 0 or 0.6% NaHCO3. The petri dishes were
incubated at 25 ◦C and the colony diameter was measured by decussation
method daily. To evaluate the effect of NaHCO3 on mycelial
biomass accumulation,
