Experiments were conducted to investigate the correlation between growth of roots and growth of above-ground parts of the wheat plant on the basis of KATAYAMA's studies on tillering. The results obtained were as follows: (1) About the time when the third leaf of the main stem emerged, its first crown roots appeared at the coleoptile node. The same phenomenon was observed in the tillering system. (2) The tillers and the roots emerged and elongated almost simultaneously at the same node of the main stem, and the same was true of the tillerstems. (3) Roots and tillers emerged in regular directions, as shown in Fig. 1.
