Abstract
  • The persistence of Sphoeropsis sapinea. Leptographiurn serpens and Heterobosidion annosurn s.s. in artificially inoculated pine branch pieces (S. sapinea and i. serpens) and wood blocks (L. serpens and H. annosurn s.s.) was investigated in order to discuss the alternative of leaving coarse woody debris in stands of Italian stone pine (Pinus pinea). Also. natural colonization by S. sapinea of pine cones of different ages was assessed. Methods used for inoculating branch pieces and wood blocks were highly effective for all fungi. Type of a forest stand in which branch pieces and wood blocks have been incubated did not affect the persistence of the pathogens in the inoculated samples. For branch pieces the success of re-isolation of L. serpens dropped as the sample incubation time increased. while S. sapinea was always successfully (100%) re-isolated (even 12 months after the inoculation). L. serpens and H. annosurn s.s. were re-isolated from most of che buried wood blocks (from more than 95% samples) up to 3 months following the inoculation. Of the observed P. pinea cones (in most cases more than 2 years old) 74% were naturally infected by S. sopinea. All three investigated pathogens were able to survive in dead plant tissues for long periods of time (at least for several (3-12) months). The persistence of these pine-pathogenic species in dead plant material questions the feasibility of leaving coarse woody debris in managed Italian stone pine forests meant for landscape conservation and leisure activities.
