2.2. In vitro compatibility of monoconidial isolates of Trichoderma
2.2.1. Cellophane culture of Trichoderma
Before carrying out experiments III–V, with combinations of
isolates of Trichoderma CH 101, CH 273, CH 303, CH 304.1 and
CH 314 (Table 1), the compatibility to each other was tested, as described
by Dennis and Webster (1971). Six millimeter diam. disks
of each Trichoderma isolate with actively growing mycelia were
transferred to Petri dishes containing PDA, one disk per Petri dish,
that was covered with cellophane sheet previously sterilised for
