Abstract

A SPAC model was employed for the analysis of the water dynamics of Salix matsudanakoidz.trees, planted on a moist meadow, at the foot of a sand dune, and on a sand dune. Calculated values with the model fitted well to the measured values. Significant differences were not observed in the pre-dawn water potentials among samples. Reflected by soil moisture conditions, the whole tree hydraulic resistances were very large on the sand dune and small on the meadow. However, on the sand dune, root extension was deep and the leaf/fine-root ratio was small, which compensated for the great resistance. Leaf conductance was small on the sand dune. Transpirational flux densities were large on the meadow, medium at the foot of dune, and small on the sand dune. Midday leaf water potential was a little less on the sand dune. Because the solute potential of leaf cells was less on the sand dune than on the meadow, the pressure potentials were inferred to be the same among sites. It was concluded that S. matsudana controlled the water dynamics process in maintaining turgor through the responses at the various levels of whole plants, organs, tissues, and cells.
