THE EFFECTS OF FLOODING ON THE TRANSPIRATION AND SURVIVAL OF SOME SOUTHEASTERN FOREST TREE SPECIES

Abstract

Results of flooding the soil in which a number of spp. of forest tree seedlings, including Pinus taeda, Juniperus virginiana, Quercus alba, Q. borealis, var. maxima, Q. prinus, and Cornus florida were growing, showed considerable similarity in decline in transpiration rate with time. Rates declined to about 30% of normal in 1 mo. and when drained, returned to normal in about 1.5 mos. Taxodium distichum did not show such a decline and Q. lyrata recovered more rapidly than other oak spp.
