• The present work was attempted to find what physical and chemical factors are necessary for the early development of the young buds of Porphyra tenera in culture. The results obtained are summarized as follows: 1. The young buds grew more rapidly under the sunlight than the artificial light. The sunlight below 25, 000 lux through a window glass was most favourable for the growth of young buds. 2. The young buds grew rapidly and healthily in daily light period. It seems that Porphyra needs an alternate light and dark-condition for the growth. The illumination of 8-9 hours per day is favourable for the growth in culture. 3. From the experiments of nitrogen and phosphorus requirements, it was found that good culture of the young buds can be obtained when potassium phosphate (monobasic) and potassium nitrate are added to the filtered inshore sea water. 4. The supply of iron as Fe-EDTA to the medium enriched with inorganic nitrogen and phosphorus promoted the growth of young buds. In iron deficient medium, the young buds grew dull in colour.
