Abstract
The concurrent exchange of SO2 and H2O vapor between the atmosphere and foliage of Geranium carolinianum was investigated using a whole-plant gas exchange chamber. Total leaf flux of SO2 was partitioned into leaf surface and internal fractions. The emission rate of SO2-induced H2S was measured to develop a net leaf budget for atmospherically derived sulfur. Stomatal resistance to SO2 flux was estimated by two techniques: (a) RsSO2′ from SO2 data using analog modeling techniques and (b) RsSO2 from analogy to H2O (i.e. 1.89 RsH2o).This publication has 19 references indexed in Scilit:
