Abstract
AbstractPhysiological and biochemical aspects of the impact of air pollutants on forest trees. The article summarizes physiological and biochemical aspects and the usefulness of these parameters as early indicators and possible causes of the current forest decline. After a description of the effects of gaseous air pollutants and acid precipitation on foliar and needle surface structures, the mechanisms underlying the uptake and translocation of these pollutants into the plant interior are evaluated. It is further described how air pollutants and their reaction products, respectively, interact with different metabolic steps of the plant. Special emphasis is layed on free radicals and their reaction product as potent inhibitors of biochemical reactions within the plant cell.
