Importance of Election of Species for Utilization of Tree in the Space Environment

There are several utilization elements in the useful usage of tree in our daily life. Tree is also one of very important elements for space agriculture after the soil formation with some organisms including microbe in the artificial life system dome such as A’MED. The space agriculture is assumed of agriculture on Mars. Before our studying about tree related to the induction into the artificial space environment system, we investigated the importance of election of tree species and their shape for useful utilization of tree in space environment based on the results of experiments using two type of Japanese cherry trees, Prunus sp.. The inside uniformity of tree were analyzed with the two analysis, acoustic vibration and chemical analysis. Tree shape is deeply affected by gravity. The election of tree species and shape is important matter when we use the tree material in space environment. Weeping type of tree would be suitable for using it in the space environment because of their inside uniformity. In addition of tree shape, the useful functional substance was analyzed. Here, we will show an approach research of the importance of election of tree species for their induction into the closed bio-ecosystem space environment in our future.
