In an effort to predict SO sensitivity of plants from their morphological and physiological features, the effects of SO on photosynthesis were partitioned between stomatal and nonstomatal components for a drought deciduous shrub, Diplacus aurantiacus, and an evergreen shrub, Heteromeles arbutifolia. As predicted, the drought deciduous shrub had the higher gas conductance, and hence SO absorptance. However, nonstomatal components also play a role in determining SO sensitivity. Apparently a plant with a high intrinsic photosynthetic capacity will be more sensitive to SO than one with a lower capacity.
为了从植物的形态和生理特征预测其对二氧化硫（SO）的敏感性，研究了SO对一种干旱落叶灌木——金喇叭（Diplacus aurantiacus）和一种常绿灌木——红果仔（Heteromeles arbutifolia）光合作用的影响，并将其分为气孔和非气孔两部分。正如所预测的，干旱落叶灌木具有较高的气体传导率，因此对SO的吸收率也较高。然而，非气孔部分在决定SO敏感性方面也起作用。显然，内在光合能力高的植物比光合能力低的植物对SO更敏感。
