| The experiments were conducted to examine the injuries of $SO_2$, $NH_3$, and $SO_2$ and NH3 mixed gas to the germination and the growth of plants. Six kinds of plants were used as the material. These plants seeds were treated with the gases for five days. Rate of the germination and the growth in height of varying plants were different according to the components of the gases. The critical concentration of the gases for both the germination and the growth were in 5ppm of $SO_2$, 50ppm of $NH_3$, and 50ppm $SO_2$ and 50ppm $NH_3$ mixed gases. When a low concentration of $SO_2$ was treated together with NH3, especially it was reduced to 60 percent of the damage in the germination and the growth. In the treatemnt with $SO_2$, the germination of the seeds which soaked in water for 24 hours reduced the injuries more 40 percent than those which for one hour. It was observed that the seeds with thick coasts or with originally intact coats were suffered but little damaged by the gases, and the external symptoms of an injury were shown, at first, in water pore, and then, in guard cell on the leaves. |
