Abstract：
:Macroscopic and microscopic measurements of the growth of Trichoderma viride and Rhizopus oligosporus were compared at different values of water activity of the solid medium. The relationship between radial extension rate and hyphal growth rate was found to be dependent on water activity. The observed difference between these two parameters was explained by the distribution of apical directions. The validity of the radial extension rate as a growth criterion could be discussed. The angular distribution of apical axes of growth in the front of the colony was observed at different water activity levels of the solid medium, and a model which links radial growth rate to hyphal growth rate and direction of apex growth was proposed and experimentally validated.
