The effects of salinity and waterlogging on stomatal conductance, net photosynthesis and transpiration of 3-month-old Eucalyptus camaldulensis Dehnh. and Eucalyptus lesouefii Maiden seedlings were studied under greenhouse conditions. Under non-saline conditions, waterlogging induced stomatal closure in both species. However, the stomata of E. camaldulensis reopened after five weeks, when adventitious roots were produced. Relative to that of controls, height growth of waterlogged seedlings was greater in E. camaldulensis than in E. lesouefii, as were rates of photosynthesis and transpiration. In a freely drained medium, high salinity reduced rates of seedling height growth and photosynthesis, relative to those in controls, less in E. lesouefii than in E. camaldulensis. In both species, height growth, stomatal conductance and photosynthetic rate were lowest under conditions of saline waterlogging.
在温室条件下，研究了盐分和渍水对3月龄的赤桉（Eucalyptus camaldulensis Dehnh.）和雷氏桉（Eucalyptus lesouefii Maiden）幼苗气孔导度、净光合速率和蒸腾作用的影响。在非盐条件下，渍水导致两个物种的气孔关闭。然而，赤桉的气孔在五周后重新开放，此时产生了不定根。相对于对照，渍水幼苗的高度生长在赤桉中比在雷氏桉中更大，光合速率和蒸腾速率也是如此。在自由排水的介质中，高盐度相对于对照降低了幼苗高度生长和光合速率，雷氏桉中降低的程度小于赤桉。在两个物种中，高度生长、气孔导度和光合速率在盐水渍水条件下最低。
