| Abstract: | Swiss chard plants were water-cultured under various B levels ranging from 0.01 to 20 g B m-3 culture solutions for 4 weeks. The B content of the shoot increased with the increase in the B supply. The increase, however, was entirely ascribed to acetate buffer (20 mol m-3 pH 4.0)-soluble B, and the content of acetate buffer-insoluble, cell wall-bound B did not increase.. More than ca. 80% of the cell wall-bound B was associated with rhamnogalacturonan II under various B levels. The amount of acetate buffer-soluble B could be estimated from the B levels in the expressed leaf sap. |
