摘要: Tropospheric ozone (O3) is one of the most detrimental air pollutants known to affect forest trees. The negative impact O3 on biomass production and physiological functions have been investigated in a number experiments (Matyssek et al. 1995, Sandermann 1997, Skarby 1998). Field observations Bavarian Forest, Germany (Baumgarten 2000) Fennoscandia (Sellden 1997) also implied that ambient might For conifers at alpine timberline however, unambiguous evidence injury did not exist, although regimes are significantly higher when compared those (Skarby 1998) low elevation sites Central Europe (Smidt
