Effect of changes in immission characteristics on the amount of epicuticular waxes in spruce (Picea abies /L./ Karst.) growing in montane regions
Original language description
The health conditions of the assimilation apparatus of forest stands can be evaluated also by means of studies on changes in the content of epicuticular waxes, which create an interface between the plant and environment and which as the first ones are damaged by immissions. Within the last decade the immission spectrum in the territory of the Czech Republic has markedly changed. Atmospheric concentrations of sulphur oxides decreased and this was the main cause of an improvement in the health condition of the Norway spruce (Picea abies/L./ Karst) assimilation apparatus. However, in the following period a marked increase in concentrations of ground-level ozone, which is at present considered to be the most serious cause of an impairment of the health condition of forest woody species in forest stands growing in altitudes above 900m. In these localities there is a repeated decrease in amounts of epicuticular waxes on the surface of needles, which is manifested in the health condition of t
