Available in PDF, EPUB and Kindle. Book excerpt: Four pot experiments are reported in which Norway spruce (Picea abies (L.) Karst) seedlings, of different nutrient status, were treated with acid mist for one growing season in open-top chambers (OTCs). Combinations of H+, SO42-, NH4+ and NO3- were applied at different frequencies of application and supplying different doses of S and N kg ha-1. Plant growth, visible injury, frost hardiness and nutrient status were observed. These experiments were undertaken to improve our understanding of the interaction of environmental factors such as nutrition and mist-exposure frequency on seedling response to N and S deposition. Both acidity (less than or equal to pH 2.7) and SO42- ions were necessary to induce visible injury. Mist containing SO42-,2-, Hi and to a lesser extent NH4+ significantly reduced winter frost hardiness. Increasing the misting frequency, and to a lesser extent the overall dose, increased the likelihood of acid mist causing visible injury and reducing frost hardiness. Post-planting stress, low N status and needle juvenility increased the likelihood of acid mist causing visible injury. Increased plant vitality, adequate N status and growth rate reduced the likelihood of acid-mist-induced reductions in frost hardiness. Principles underlying the responses of spruce seedlings treated in controlled conditions to acid mist are discussed.
