ABSTRACT
Current year seedlings of 14 bottomland tree species surviving 60 days of completely water-saturated soil conditions were compared to check seedlings grown under well-watered but nonsaturated soil conditions. Comparisons were made of the following: dry weight per seedling top, and contents of ash, N, P, K, Ca, and Mg. Based on root and shoot growth and nutrient absorption, the species are grouped according to their relative tolerances to watersaturated soil conditions as follows: Tolerant—Nyssa aquatica, Fraxinus profunda, Salix nigra, Fraxinus pennsylvanica; Intermediate—Quercus palustris, Populus deltodis, Platinus occidentalis, Acer negundo, Acer rubrum, Acer saccharinum; Intolerant—Ulmus americana, Celtis occidentalis, Liquidambar styraciflua, Celtis laevigata.
