The studies of the individual environmental factor affecting the growth of Porphyra were carried out under the indoor culture condition suitable for the growth of Porphyra. The results obtained are summarized as follows: (1) The cell division of Porphyra was activated with the decrease of light intensity from 10, 000 lux to 6, 000 lux irradiation, and from 6, 000 lux to 1, 000 the cell division occurred with almost the same rate. The cell size became smaller with the decrease of light intensity. (2) The growth of Porphyra-frond was most rapid under 6, 000 lux irradiation. (3) The cell division of Porphyra was activated and the cell size became smaller with the drop of water-temperature from 20°C. to 10°C. (4) The growth of Porphyra-frond was most rapid at 15°C. (5) The color of Porphyra-frond was remarkably affected by light intensity and watertemperature.
