Norway Spruce Function in Polluted Environments
The economic importance of Norway spruce (Picea abies) is a key reason why this species has been the subject of numerous studies of the impacts of toxic pollutants on forest trees (Bennett and Buchen 1995). Experiments with Norway spruce are also justified owing to a large intraspecific variation in tolerance to environmental pollutants. Genetic variation may, in part, explain contrasting findings among published results of pollution tolerance. In addition, genetic variation enables selection of individuals, clones (Kriebitzsch et al. 1996; Longauer et al. 2001) or whole populations (Havranek et al. 1990; Geburek and Scholz 1992) that are relatively tolerant to the influence of toxic compounds.
