Description Heterobasidion annosum (Fr.) Bref., also known as annosum root rot, is considered to be the most economically important forest pathogen in the Northern Hemisphere. This pathogen is the biggest threat to coniferous trees. This study was carried out in Lithuania (Kaunas city), in the experimental forest where the former agricultural field was afforested by Scots pine (Pinus sylvestris L.) stands 50 years ago. This engendered the spread of disease. Research was based on analysis of concentration of metals (Zn, Cu, Mg, K, Cd and Pb) in wood as well as in soil samples. Results showed significant higher concentrations of K and Mg in infected wood samples because of the decay caused by pathogen which had created a sink region in the infected tissues and that elements moved from the unaffected areas to the zone of infection.
Šakninė pintis (H. annosum) – ekonomine prasme viena svarbiausių miško ligų sukėlėjų Šiauriniame Pusrutulyje. Tai daugiausia žalos sukelianti liga spygliuočiams. Tyrimas buvo atliktas Lietuvoje, Kauno mieste, eksperimentiniuose Dubravos miškuose, kur pušynas buvo apželdintas ant buvusios dirbamos žemės prie 50 metų. Tai buvo viena iš priežasčių paskatinusių ligos plitimą. Tyrimų metu buvo analizuojami metalai (Zn, Cu, Mg, K, Cd ir Pb) medienos ir dirvožemio ėminiuose. Tyrimai parodė reikšmingus skirtumus tarp pažeistų ir kontrolinių medienos ėminių K ir Mg koncentracijose. Tai siejama su medžio puviniu, kuris sudaro sritį pažeistame audinyje ir elementai juda nuo nepažeistos vietos puvinio link.
