Efekt biotyczny pomiędzy grzybami zasiedlającymi drewno modrzewiowe a pniarkiem modrzewiowym (Fomitopsis officinalis)

The review of regeneration processes after tree stem wounding is given. The wounds can be caused by various abiotic and biotic factors and also by human activities. The regeneration processes differ between shallow and deep wounds. Regeneration of deep stem wounds involves both filling the cavity and regeneration of the cambial surface. The pattern of cambial activity and differentiation xylem tissues are modified at various distances from the wound edges. Involvement of mechanical stress in the regeneration processes is discussed.
