Responses to sequential exposure to SO2 and salinity in soybean (Glycine max L.)

Assessment report on sulphur dioxide for developing ambient air quality objectives : effects on vegetation

“…Top-covered chambers were used to investigate visible injury, growth, and stomatal resistance of soybean {Glycine max L.) cv. Buchanan when exposed to salt stress followed by SO2 or SO2 followed by salt stress (Qifu and Murray, 1994). Plants were exposed to 380 or 786^g m'^SO2 for 5 h per d, for 3 weeks followed by exposure to low (320 g/200 L) or high (540 g/200 L) salt stress for an additional 3 weeks.…”
