  • In order to evaluate the trunk health of Ginkgo biloba trees and reduce the risk of trunk breakage and collapse, this study used PiCUS Tree Tronic tree electrical impedance tomography to detect the state of healthy, dry and rotten of Ginkgo biloba trunks, respectively, and compared with the visual inspection results. The tomographic results showed that the resistivity of the healthy trunk was high in the middle and low in the periphery. The resistivity in the middle of trunk reached 1 000 Ω·m, and the resistivity around the trunk was about 300 Ω·m. The dry ginkgo stems showed high resistivity, with an average resistivity of more than 1 000 Ω·m. The difference on the resistivity of the decayed trunk was related to the size of decayed area, and the proportion of the decayed area was generally higher than that of the visual result, indicating that the electrical impedance technology can detect the health status of the trunk more accurately. The results can provide guidance for the health assessment of the trunk of Ginkgo biloba.

The dry ginkgo stems showed high resistivity, with an average resistivity of more than 1 000 Ω·m. The difference on the resistivity of the decayed trunk was related to the size of decayed area, and the proportion of the decayed area was generally higher than that of the visual result, indicating that the electrical impedance technology can detect the health status of the trunk more accurately. The results can provide guidance for the health assessment of the trunk of Ginkgo biloba.
