Experimental studies on SO/sub 2/ injuries in higher plants. Part 4

Abstract

The effect of sulfur dioxide on aminoacid metabolism was examined. Wheat seedlings one month old (20 cm) were exposed to 0.5 ppm SO/sub 2/ at 22/sup 0/C, and 40% humidity for four days, only during the day. A Beckman 1200 aminoacid analyzer revealed only slight effects, but it was conjectured that the plant had some separate amino acid in its body prior to the test, and that the effect of SO/sub 2/ was relatively low. A similar wheat seedling was placed in a closed glass container and was exposed to 300 ppm carbon dioxide (14) and 100 ppm SO/sub 2/ for 30 min under 4000 lux. The first paper chromatography of 80% ethanol solubles from the leaves revealed that Ala. value had increased but sir. had decreased in half. The second paper chromatography revealed that in both test and control plants, four kinds of material in amino acid had taken in C(14), and two of the four were Ser. Ala. The total C(14) taken in by the test material under SO/sub 2/ exposure showed a noted decrease. The experiment proved that exposure of a plant to a high concentration of SO/sub 2/ produced hydroxysulfonate in metabolism and impaired its glycol  More>>
