Responses of pine needle endophytes to air pollution
Summary The effects of heavy metals and sulphuric acid on pine needle endophytes were studied using gradient analyses, an experimental field study and an in vitro laboratory experiment. Gradient analyses were carried out near factory complexes at Harjavalta (southern Finland) and Monchegorsk (Kola p...
