| Abstract: |
| With the stem heat balance method to measure the plant transpiration, the sap flow of tomato was analyzed, and the daily variation of sap flow was discussed. On the base of the data from an automatic collection system to monitor environmental and meteorological factors, the relationships between the sap flow and environmental factors were analyzed comprehensively. Meanwhile, the quantitative relationship between transpiration and environmental factors was established, and the relationship between stomatal conductance and transpiration rate was studied. |
