Abstract
Abstract Soybean [ Glycine max (L.) Merr.] cv. Elf plants were exposed to 0.0, 0.05, 0.2, and 0.4 µ mol mol −1 SO 2 in a controlled environment. The amount of abscisic acid (ABA) was measured, using an enzyme linked immunosorbent assay (ELISA), after 1, 2, or 4 h of exposure as well as after 18 h of recovery period. With 0.05 µ mol mol −1 SO 2 , the ABA concentrations in soybean leaves were 28 and 141% higher than the control, with 1 and 4 h exposures, respectively; after an 18‐h recovery period, the ABA concentrations were still higher (23.6 and 42.8% for the 1 and 4 h exposures, respectively). Abscisic acid concentration increased in soybean leaves both with an increase in the concentration of SO 2 and the time of exposure.
