One of the preconditions for the effective fight against the plant diseases is the knowledge on the bioecology of pathogens. This paper presents the results of the research of the influences of temperature, light and different media on the growth and characteristics of mycelia of fungus Cryphonectria parasitica. The influence of temperature was studied on two isolates, at the temperatures ranging from 4 and 39 deg C. The optimal temperature for its growth, as well as the interval in which the fungus is physically active, was determined. The influence of light was studied by using 16-hour photoperiod, whereas the growth and characteristics of mycelium were studied on three different media. The results point out to the fact the optimal temperature for the mycelium growth is 25 deg C, that mycelium grows more slowly by daylight, and that the most favourable medium for the mycelium growth is PDA.
