It was observed that in Helianthus tuberosus L., the phyllotaxy was opposite in early stage and changed to alternate at about 1.5 months before the flowering. From these observation, it was considered that the change of leaf arrangement showed the time of the alternation from vegetative growth to reproductive growth. So, this experiment was carried out to study the relationship between change of phyllotaxy and growth phase. Morphological and histochemical methods were used in these studies and the results were as follows; (1) The change of leaf arrangement occurred at the middle of July. (2) At that time, the shoot apex changed slowly from flat type to dome type. (3) Histochemical change of the nucleic acid (RNA) indicated the change of the growth phase. From these results, it was considered that the change of phyllotaxy was applicable as an indicator of the alternation from vegetative growth to reproductive growth in Helianthus tuberosus L.
