Czy Penicillium adametzii może ograniczyć pasożytniczą zgorzel siewek sosny zwyczajnej?

Mixture of the Penicillium adametzii metabolites present in the chloroform extract usually did not inhibit the growth of damping−off fungi, including C. destructans, F. oxysporum. F. sambucinum, F. solani and R. solani, in vitro. Extract from the P. adametzii liquid culture: (i) protected the inoculated pine seedlings from the damping−off only temporarily, (ii) decreased the health of the non−inoculated seedlings, (iii) caused the temporary increases of the fungal population in soil, (iv) changed structure of the soil fungi communities, and (v) caused the continuous increase of Trichoderma, mostly T. aureoviride population. The increase of pine seedlings damping−off was connected with the increase of T. aureoviride population in soil. Natural isolates of P. adametzii cannot be considered as the effective biological factor in the biological control of damping−off.
