Abstract: Using tissue slices excised from cold-stored Jerusalem artichoke tuber, the following results were obtained in connection with the growth as determined by relative wet weight increase. 1. Remarkable growth was caused by 2, 4-D plus kinetin (1mg and 1mg/l), less remarkable growth by 2, 4-D alone, and no appreciable growth by kinetin. The growth caused by 2, 4-D plus kinetin and by 2, 4-D was larger in the case when tissue slices were previously “washed” (or “aged”) by water for 15-20 hours than in the case of no previous washing. Washing with gibberellic acid solution (5mg/l) was more effective than washing with water.2. The larger the growth, the larger the decrease in dry weight of the tissue. Inulin in the cell disappeared during the 50 hours' growth of tissue slices.3. Growth promotion by gibberellic acid and kinetin did not seem to be due to enhanced auxin absorption by the tissue.4. Osmotic value of cells didd not change during the washing and during the expansion growth.5. Elastic and plastic extension of the cell wall was estimated by a plasmolysis method.
