title: Structural and functional changes in photosynthetic apparatus of wheat under exposure to sulfur dioxide fumes.
abstract: Changes in photosynthesis of wheat (pigment content and chlorophyll fluorescence) have been measured to study effect of gaseous sulfur dioxide on wheat cenosis. Several biochemical and biophysical techniques have been estimated to evaluate their ability for early detection of destructive effect of SO2. A mathematical model of toxic gas absorption in a closed system with plants has been proposed.
