The effect of disturbed mineral nutrition on Picea omorika Pančić needles - a single case study

A widespread conifer forest decline in Europe and North America has been expressed through various combinations of symptoms. The unspecific biochemical indicators and histological findings were compared with visually assessed damaging symptoms in order to get a detailed diagnosis of declining a single Pančić spruce (Picea omorika Pančić) tree. By measuring the content of photosynthetic pigments and proteins as well as total guaiacol peroxidase activity we confirmed an altered physiologocal state of investigated tree. Histological analysis showed the specific pattern of declining for Mg and K deficient trees.
