Sap flow in plant stems plays an important role to transport fluid and nutrients internally from roots to leaves. In this study, the sap flow in tomato stems was assessed using a heat flow method at 0.01 and 1.0 g for 20 seconds each during parabolic airplane flights in order to clarify the effect of microgravity on the sap flow in stems. Heat generated with a small heater installed in the stem was transferred upstream and downstream by conduction and upstream by convection with the sap flow through xylems of the vascular tissue. Thermal images of stem surfaces near heated points were captured using infrared thermography and the internal heat convection corresponding to the sap flow was analyzed. In results, the sap flow in stems at 0.01 g was suppressed under a retarded air condition at a wind speed of 0.1 m/s compared with that at 1 g. No suppression of the sap flow was observed under a stirred air condition at a wind speed of 0.5 m/s. Suppressed sap flow in stems would be caused by suppression of transpiration in leaves and would cause restriction of water and nutrient uptake in roots. The forced air movement is essential to grow healthy plants under microgravity condition in space., 形態: カラー図版あり, 共催: 日本学術会議, 著者人数: 16人, Physical characteristics: Original contains color illustrations, joint hosting: The Science Council of Japan, 資料番号: AA0064730062},
