| Popis: | The effects of air pollution in the form of 6 concentrationsof SO2 (ranging from 0 – 520 μg/m3) on 9 week-old seedlings of Pinus sylvestris L. were studied. Seedlings were uninoculated or inoculated with the mycorrhizal fungi Paxillus involutus or Laccaria proxima . Exposure to SO2 for 7 weeks decreased the photosynthesis and the cold sensitivity of the plants significantly. Mycorrhizal formation of L. proxima was not affected by the treatments, whilst that of P. involutus decreased significantly from 120 μg/m3 SO2 onwards. |
