Description:
Variation in metabolic responses to sulfur dioxide is widespread within many plant species. Plant responses are a consequence of a series of biochemical and physiological events beginning with SO2 flux into plant and progressing through perturbation, and homeostasis, and ending with foliar injury and/or effects on growth and yield. Gas-phase and liquid-phase conductance are important determinants of SO2 flux. However, the relationship between variation in these factors and plant response is incompletely understood--at least in part because of difficulties with SO2 gas-exchange methodology. Perturbation events occurring primarily in the chloroplast, and homeostatic mechanisms have received only brief attention.
