Dynamika rozwoju opieńkowej zgnilizny korzeni w uprawie doświadczalnej z sadzonkami sosny zwyczajnej (Pinus sylvestris L.) niemikoryzowanymi i mikoryzowanymi grzybami Hebeloma crustuliniforme i Laccaria bicolor

The objective of the research was to study the Armillaria root rot dynamics in the experimental plantation with Scots pine (Pinus sylvestris L.) seedlings non−mycorrhized and mycorrhized with the fungi Hebeloma crustuliniforme and Laccaria bicolor. It was demonstrated that eight years after planting, the container−grown pine seedlings mycorrhized with the fungi H. crustuliniforme were affected by the Armillaria root rot disease in relatively lesser degree in comparison with the seedlings subjected to such treatment.
