Tropospheric ozone is a widespread and phytotoxic air pollutant in the industrialized world and causes reduced growth in many tree species. It is therefore important that, for example, the responses of the economically important loblolly pine to ozon

The aim of the present study was to determine how long-term nutrient optimisation of Norway spruce stands affects the chemical composition of stem wood. Material for the study was collected from Flakaliden (Sweden) where Norway spruce [Picea abies (L

The ultrastructure of current and previous year needles of Scots pine (Pinus sylvestris L.) and Norway spruce (Picea abies L.) Karst. was studied after exposures to several different ozone concentrations (100 to 600 nL∙L−1) and doses in a chamber

Scots pine (Pinus sylvestris L.) seedlings were fumigated with 1.2–1.5 x ambient ozone (cumulative exposure) over 2 seasons in an open-air experiment. Starch and fatty acid concentrations were analyzed in needle and root tissue in the summer, autum
