Zusammenfassung

Der Gehalt der fungitoxischen Substanz p-HAP in ein- und zweijährigen Fichtennadeln wird durch die Ozonbelastung im Vergleich zur Kontrolle erniedrigt. Die Düngung mit Mg und Ca wirkt sich positiv auf den Gehalt an p-HAP in den Nadeln aus.

Influence of mineral nutrition, ozone, and acid mist on the content of the fungi-toxic compound p-Hydroxyacetophenon in spruce needles (Picea abies [L.] Karst.)

Summary

The concentration of the fungi-toxic compound p-HAP of 1- and 2-year-old spruce needles is decreased after ozone treatment as compared to control needles. Fertilizing with Mg and Ca has a positive effect on the content of p-HAP of spruce needles.
