RHIZOCTONIA SPP. - DAMPING-OFF PATHOGENS OF SCOTS PINE (PINUS SYLVESTRIS) SEEDLINGS IN NOWY DWóR FOREST NURSERY VERSUS SOIL FUNGI COMMUNITY IN 2006

摘要

Nowy Dwór forest nursery (Forest District Lipka in north-western Poland) is one of the nurseries where damping-off of Scots pine occurs every year with high degree of seedling infestation.In 2006 chosen binucleate and multinucleate Rhizoctonia isolates from the nursery were tested versus the soil fungi community, to compare the situation with that from the two previous years. The community supported the growth of all the isolates, yet thesupport to the multinucleate ones (R. solani) was greater. The situation reflected that of 2004 and 2005.
