Changes in transpiration rate of SO2-resistant and -sensitive plants with SO2 fumigation and the participation of abscisic acid

Peanut and tomato plants were resistant to 2.0 ppm SO2, while radish, perilla and spinach plants were sensitive. The amounts of SO2 absorbed by peanut and tomato were obviously less than those absorbed by radish, perilla and spinach. Transpiration rates of peanut and tomato began to decrease within 5 min after the commencement of SO2 fumigation and reached minimum levels, i.e., 10 and 50% of the initial levels, respectively, after 20 min exposure. The rate of perilla did not change for 70 min alter initiation of fumigation, then declined. Those of radish and spinach did not change for about 20 and 30 min, then decreased gradually. The content of abscisic acid (ABA) was highest in peanut. The content in tomato was also high, but low in radish, perilla and spinach. Radish supplied with exogenous ABA began to decrease its transpiration rate immediately after SO2 fumigation and was markedly resistant to SO2. ABA in leaves may control the rapid stomatal closure following SO2 fumigation.
