Lighting conditions in the artificial culture of laver thalli were studied, and the following results were obtained. 1) Under continuous lighting using white light with constant light intensity, the growth of laver thalli was good at the range of light intensity of 5.5 to 8 KIx and at the lighting period of 8 to 10 hours a day. 2) When intermittent lighting intensity was varied 1.2 to 8.4 klx or to 200 klx, the growth of laver thalli was almost the same as that in the case of continuous lighting, or showed above 80% of the growth of thalli under the same total light quantity a day as that in the former case. 3) When the light intensity was about 1 klx, the growth of laver thalli was improved by supplementing some kinds of sugars and salts of organic acids, especially arabinose to the culture media. But under the complete dark condition, the growth of laver thalli was not improved by supplementing sugars and salts of organic acids to the culture media.
