Osmotic potential of several hardwood species as affected by manipulation of throughfall precipitation in an upland oak forest during a dry year.

Components of dehydration tolerance, including osmotic potential at full turgor (Psi(pio)) and osmotic adjustment (lowering of Psi(pio)), of several deciduous species were investigated in a mature, upland oak forest in eastern Tennessee. Beginning July 1993, the trees were subjected to one of three throughfall precipitation treatments: ambient, ambient… CONTINUE READING
