Physiological responses to light availability and soil flooding on Lindera melissifolia (Walt.) Blume were studied. Shrubs were grown under 70, 37 or 5% of full sunlight with either 0, 45, or 90 d of soil flooding. We measured leaf photosynthetic rate (PN) to test the hypothesis that soil flooding reduces PN in L. melissifolia following shrub acclimation to low light availability. Results showed that light availability and soil flooding interacted to affect PN. In the 0 d and
45 d flooding regimes (flood water removed 36-39 d prior to measurement), PN was similar between shrubs receiving 70% or 37% light, and these shrubs had 147% greater PN than shrubs receiving 5% light. Shrubs receiving 90 d of soil flooding had similar low rates of area-based PN regardless of light level. Similar PN between 0 d and 45 d flooded shrubs indicated physiological recovery following removal of flood water., B. R. Lockhart, E. S. Gardiner, T. D. Leininger, M. S. Devall, A. D. Wilson, K. F.
