Einfluß von Mineralstoffernährung, Ozon und saurem Nebel auf Peroxidase-Aktivitäten in Fichtennadeln, Picea abies (L.) Karst.
The effect of mineral nutrition, ozone and acid mist on peroxidase activity in needles of Norway spruce, Picea abies (L.) Karst.
Eur. J. For. Res. 105, 252-254 (1986)
As part of the first experiment of MAGL (Munich working group on air pollutants), peroxidase activity was investigated in spruce needles treated with ozone, acid mist, and differential Ca and Mg nutrition. The enzyme shows decreases, increases, or undifferentiated response depending on needle age and treatment. POD in needles from 1984 generally decreased with ozone and/or acid mist treatment. Needles from 1983 showed reduced activity after the ozone treatment, too. Acid mist, however, caused an increase in POD-activity in 1983 needles, but there was no influence in POD in 1985 needles due to acid mist. Fertilization of the soil with Ca and Mg entails higher POD in needles of those plants which were kept within the chambers whereas fertilization of comparable plants kept in the field brings about a decrease of POD-activity. This enzyme responds to many different factors, and these responses a very heterogeneous. Hence measurement of the activity of the total soluble peroxidases is not considered to be an useful bio-indication system for air pollutants.
