Abstract

Growth of terminal shoots of potted sycamore, sweetgum, and Nuttall oak seedlings began to decrease when leaf water deficits reached 6 to 9 percent. Growth limiting soil moisture tensions were much lower and occurred much sooner in Commerce silt loam than in Sharkey clay. Transpiration was greatest in the fastest growing individuals; it decreased steadily as tension increased.
