Long-term exposure of Norway spruce, Picea abies (L.) Karst., to ozone in open-top chambers : I. Effects on the capacity of net photosynthesis, dark respiration and leaf conductance of shoots of different ages
Rates of net photosynthesis were measured on Norway spruce, Picea abies (L.) Karst. exposed to three different concentrations of ozone for three seasons (1985-7) in open-top chambers. The treatments were non-filtered air + ozone (NF +), non-filtered air (NF) and charcoal-filtered air (CF). Ozone was...
