Assessment of the Tolerance of Trees to High Concentration Sulfur Dioxide

Abstract:

Italic textThis research utilized a custom-made air fumigation equipment to evaluate the tolerance of 10 species of side-walk trees with 600, 1000 and 2000 ppb Sulfur Dioxide (SO₂) for 48 hours. The tolerance of tested trees toward SO₂ pollution was analyzed. Results showed that these plants influenced by high concentration SO₂ gas with physiology properties changes and the decrease of photosynthetic rates and the stomata conductance than before fumigation. The net photosynthetic rate and stomata conductance of tested trees was linearly correlated to each tested tree species. Among tested tree, the Quercus glauca had the highest tolerance in exposure with high concentration of SO₂ pollutant. While the Camellia axillaries was the least.
