Z. Naar et M. Kecskes, FACTORS INFLUENCING THE COMPETITIVE SAPROPHYTIC ABILITY OF TRICHODERMA SPECIES, Microbiological research, 153(2), 1998, pp. 119-129
The competitive saprophytic ability of twenty-eight strains of eight T
richoderma species (T. atroviride, T. aureoviride, T. hamatum, T. harz
ianum, T. koningii, T. piluliferum, T. pseudokoningii, and T. viride)
was determined with an agar disk method. A wide range of this property
was found among strains independently of their origin suggesting the
necessity of selection before applying them in soil. In vitro growth r
ate at different temperatures, cellulolytic activity and sensitivity o
f the selected Trichoderma strains to in vitro inhibitory effect of va
rious test bacteria and fungi were determined and used for multiple re
gression analyses. Models based on the investigated parameters suggest
ed that the tolerance to inhibitory effect of bacteria accounts mainly
for the competitive success of Trichoderma.
