Chemical and Morphological Composition of Norway Spruce Wood (Picea abies, L.) in the Dependence of Its Storage
Round 1
Reviewer 1 Report
Table 2 I recommend to state the minimum and maximum value of the parameter
or add to the supplement: graphs displaying temperature vs. storage periods, Humidity vs. storage period, precipitation vs. storage period
page 3 line 96: incorrect name of reference Wiese (correct Wise)
Use the term height (remove / replace high)
Has the ash content been measured? Fill in the data.
Can you state what the loss of mass after storage is?
From the literature, you can indicate which extractive substances / types predominate in the wood / bark after storage.
What causes changes to the wood biomass during storage? What mechanisms cause it, add information.
Add information on the main reactions that occur when storing wood in terms of extractives.

Response to Reviewer 1 Comments
Dear reviewer, thank you for your suggestions.
Table 2 I recommend to state the minimum and maximum value of the parameter or add to the supplement: graphs displaying temperature vs. storage periods, Humidity vs. storage period, precipitation vs. storage period
Answer: I stated the minimum and maximum value (Table 2)
page 3 line 96: incorrect name of reference Wiese (correct Wise)
Answer: I corrected it
Use the term height (remove / replace high)
Answer: I corrected it
Has the ash content been measured? Fill in the data.
Answer: We don´t measured the ash content
Can you state what the loss of mass after storage is?
Answer: We didn´t follow the loss of mass after storage.
From the literature, you can indicate which extractive substances / types predominate in the wood / bark after storage.
Answer: I added it
What causes changes to the wood biomass during storage? What mechanisms cause it, add information.
Answer: I added it
Add information on the main reactions that occur when storing wood in terms of extractives.
Answer: I added it

Reviewer 2 Report
The manuscript entitled “Chemical and Morphological Composition of Norway Spruce 2 Wood (Picea abies, L.) in Dependence of Its Storage” This work is merit for publication at Polymers after some major modification. So I have some points that may help to improve the work as follows:
1-Abstract is good but need more explain about the main aim of work
2- The introduction should be extended to discuss the hypothesis and research questions in details. Additionally, the introduction should cover the recent literature related to this subject.
3- Material and methods
The methodologies should be explained in details so that the results are reproducible.
4-Results
The results are clear and important.
5-Discussion
The discussion section still needs improvement, and should be linked to the findings of the previous reports on this topic.
6- The conclusion
A section for conclusions need more explain and should include the most significant findings and future works only.
7- English writing should be checked by a native English speaking expert.

1-Abstract is good but need more explain about the main aim of work
Answer: We have no space for other explanation because of restriction of words number in abstract.
2- The introduction should be extended to discuss the hypothesis and research questions in details. Additionally, the introduction should cover the recent literature related to this subject.
Answer: I added the recent literature to the Introduction part.
3- Material and methods
The methodologies should be explained in details so that the results are reproducible.
Answer: Thank you for the opinion, this Methods was published many time as it is. There are presented standards and chemical analysis can be provided according them.
4-Results
The results are clear and important.
Answer: Thank you so much!
5-Discussion
The discussion section still needs improvement, and should be linked to the findings of the previous reports on this topic.
Answer: We added some discussion to this part.
6- The conclusion
A section for conclusions need more explain and should include the most significant findings and future works only.
Answer: We added some information.
7- English writing should be checked by a native English speaking expert.
Answer: we did so
Round 2
Reviewer 2 Report
