| Outline of Final Research Achievements |
In case of tree transplanting for large tree, it is forced to cut the tree canopy and derogate the root systems. Gardeners understand empirically which wood species is sensitive to the transplantation work and which size of root ball is suitable to avoid severe damage for tree body. In this study, we collect useful sap flow data for tree transplantation work, accurate measurement of sap flow movement before and after root preparation and transplanting allows us to predict transplant success or failure.
Thermal dissipation method has been widely used in Japan and there are quite a few numbers of studies measuring sap flow in large tree in a forest by heat ratio method and heat field deformation method. These three methods were applied for a mature tree of Japanese cedar and stem segments connected with vacuum pump to generate artificial sap flow to conduct calibration work.
