Numerous attempts have been made to construct the controlled ecological life support systems (CELSS). The system will be a unique tool for researches such as test beds for the global change problem, the solutions for a zero-emission society and the large-scale life support system in outer space. The morphogenesis of plants in the system may be affected by the environmental change derived from the scale-down in ecological system. However, if the morphogenesis of plants is made clear, the high efficiency and intentional agriculture system will be put into practice. The purpose of this report is to elucidate the photomorphogenesis of plants under the variety of irradiation conditions. The experimental results showed that the changes in irradiation period had a dramatic effect on the germination, the differentiation and the growth of plants. In the 12-hours cycle irradiation which was composed of 6 hours-bright and 6-hours dark, the growth was promoted, although the germination of peas was restricted. Mechanisms based on phytochrome, photosynthesis, circadian rhythm and source-sink relation were proposed to explain these behaviour.
