Introduction

Why did the authors choose these particular parameters? The cell dimension appears to lack an evident correlation with the electrical properties of wood. Could you explain the rationale behind this choice?

As mentioned in the introduction, some studies reported that wood's density, hardness, and moisture content strongly correlate with its electrical properties. Please introduce the correlation between the anatomical characteristics of hardwood and its physical properties.

·       based on research on small wood samples by Esofita et al. (2015), it was explained that anatomical structure has a relationship with the wood capacitance. More vessels and parenchyma cells related on lower wood density as well as wood hardness and capacitance value. The more fibre, the higher the cellulose. Since cellulose is a polar molecule, so the polarity is high, the higher the capacitance value. According to these findings we thought that it is a challenge that capacitance and/or dielectric properties can predict the proportion of wood anatomical properties. I this paper we tried to predict the anatomical dimension. However, the results were not accurate, so through this study it was shown that dielectric properties cannot specifically predict anatomical dimensions.

Results

Please discuss the results of the relationship between the cell dimension and the electrical properties. Why did the cell dimension show a weak correlation with the electrical properties?

·       the electrical properties seem has relationship with the proportion of anatomical structures i.e. vessels and parenchyma cells in the wood, but can’t specifically predict the dimension of each anatomical structures. Especially, because trees are living material so that the structure of cell dimensions can be different even for the same species of trees.

Conclusion

The conclusion appears overly broad, lacking specific recommendations for further study. It would be beneficial to propose clear avenues for exploration to enhance the significance of this work and guide future research efforts.

#Introduction

1)

The introduction is well-written and provides a good background and context for the manuscript. However, it could be more focused and brief, avoiding unnecessary details and repetitions.

·       Thank you for the suggestion, we have removed the unnecessary details and repetitions

2)

In lines 59-60, I would recommend that the authors mention the applied methods in the literature.

#Material and Methods

1)

The authors indicated that three different ages of trees were selected for the DS. In my opinion, 3 trees are not enough for DS analysis as well as for physical an anatomical properties.

Reply:

·       Thank you for the suggestion, we did not use 3 trees but 30 trees for each age of the tree, making a total of 90 trees. This is considered sufficient to describe the characteristics of the tree at each age, because the selection of the sample was random.

#Results and discussion

1)

The results section is well-organized and provides a detailed description of DS results, physical and anatomical properties as well modeling. However, the authors should compare the obtained results with the other relevant studies as well as I recommend the authors consider avoiding unnecessary details and repetitions in all sections of the results and discussion

Reply:

·       Thank you for the suggestion, the explanation have been added to the paper and the repetition was removed.

#Conclusion

1)

I would recommend adding this suggestion: compare the obtained with similar NDT methods like tree tomography

·       Thank you for the suggestion, the comparation have been added

Introduction

he written response was copy-pasted from the manuscript without giving any context to my suggestion.

In the present study, the authors determined the relationships between dielectric characteristics and the physical and anatomical properties. The authors clearly introduced the relationship between electrical and physical properties (in 3rd paragraph). The current research on the relationships between dielectric properties and anatomical characteristics should be introduced.

·       Thank you for the suggestion, the recent studies related to dielectric properties and anatomical characteristic of wood has been added into introduction in 3^rd paragraph
