To clarify the factors controlling sulfur gas emission from plants, we studied the effect of temperature and light intensity on sulfur gas emitted from rice and soybean, and the effect of sulfur concentration in the nutrient solution on sulfur gas emitted from rice, soybean and Chinese cabbage under a laboratory experiment. CH_3SCH_3 (DMS) flux from rice and soybean increased exponentially with rising air temperature, and the activation energy for DMS flux from rice and soybean was 59700 and 96600 J mol^<-1>, respectively. DMS flux from rice and soybean also increased with light intensity to be 2.1 and 2.4 times, respectively. DMS flux from rice and CH_3SH flux from Chinese cabbage in the no nutrient sulfur plot were less than those in the sulfur-added plots, although DMS flux from soybean was not influenced by the nutrient sulfur level.
