Four communities of saprotrophic fungi from a forest nursery soil were tested for their effect on the in vitro growth of damping-off pathogens: Rhizoctonia solani, Fusarium avenaceum, F. culmorum, F. oxysporum and F. solani in relation to incubation temperature (5, 10, 15, 20 or 25°C) and medium pH (4.3; 5.6 or 7.5). The soil fungi communities weakly suppressed the growth of pathogens studied only at the lower temperatures (5 or 10°C). At the higher temperatures the communities tested supported the growth of all pathogens. The supporting effct was increasing with the increase of temperature, independently of pH. The effect was highly dependent on incubation temperature and not dependent on medium pH (P
