Fig. 7. — Effect of silicon application and osmotic stress on the root hydraulic conductance (Lp) in hydroponic culture. The whole-root system of seedlings under control (open symbols) or PEG treatment (filled symbols) with (squares) or without silicon (triangles) was cut off near the root base, leaving 4cm of mesocotyl, and inserted into the pressure chamber. For a given applied gas pressure, the volume exuded from the root system was plotted against time. (A) The slope of these relationships referred to unit root surface area was denoted as the Lp. (B) The means ±SD are shown. (C) The root surface used to calculate the Lp. Values are means ±SD of five replicates. Different letters indicate a significant difference (P<0.05).
