A fundamental study was conducted to develop the experimental system to investigate effects of space environment on vegetative and reproductive growth of plants in their life cycles. In this study, the transpiration rate of plant leaves were evaluated at 0.01, 1.0 and 2.0 g for 20 sec each during parabolic airplane flights in order to clarify effects of microgravity on the water vapor exchange between plants and the ambient air. The transpiration rate of leaves was suppressed by increasing the water vapor transfer resistance due to restricted free air convection under microgravity conditions. Planning for evaluating performance of the water recycle system in a plant growth chamber under microgravity conditions is also described.
