title: [Radial growth rate of fungal colonies in respect of their ecology].
abstract: Indices of the radial growth rate of colonies were determined for Circinella circinans and Mortierella ramanniana as well as for the complex of fungi in soil in the course of microbial succession. The maximum of growth (Kr = 0.053 cm/hr) for C. circinans was observed at a high concentration of glucose (10%) in the medium, whereas for M. ramanniana the maximum (Kr = 0.0054 cm/hr) was detected at a low glucose concentration (0.005%) in the medium. These data account for the position of C. circinans and M. ramanniana in the course of microbial succession in the natural habitat. Kr was used to establish the origin of successional changes in the complex of soil fungi in serozem upon the introduction of glucose.
