| Outline of Final Research Achievements |
Understanding capability of plants to adapt themselves to altered gravity environments is crucial to secure a stable food supply in a long-term space exploration. It is necessary to clarify effects of altered gravity environment on the life cycle of plants to successfully develop such a cultivation system in space. In this study we continued to improve an apparatus to perform long-term plant cultivation under hypergravity and to optimize other environmental conditions than gravity, and examined its effects on the life cycle of Arabidopsis and Physcomitrella. And we found that long-term hypergravity increased biomass of Physcomitrella. We also performed anatomical observation regarding effects of long-term microgravity as well as 3 G-hypergravity on the formation of tissues in the peduncle of Arabidopsis and obtained results, though still preliminary, indicating a possibility that gravity suppress formation of pith cavity as well as fibers.
