The Effects of Several Metal Nanoparticles on Seed Germination and Seedling Growth: A Meta-Analysis
Round 1
Reviewer 1 Report
Based on the results of an in-depth evaluation that I have done for a article with the title “Functional Nanoparticles for Environmental Contaminants Removal and Agricultural Application”, I think this article should be rejected for publication in Coatings or reconsider after proper changes in major revision.
- I would encourage and advise the authors to adopt some of the additional references in author’s present article in the introduction section published by MDPI as follow:
Tresca Stress Simulation of Metal-on-Metal Total Hip Arthroplasty during Normal Walking Activity. Materials (Basel). 2021, 14, 7554. https://doi.org/10.3390/ma14247554
The Effect of Bottom Profile Dimples on the Femoral Head on Wear in Metal-on-Metal Total Hip Arthroplasty. J. Funct. Biomater. 2021, 12, 38. https://doi.org/10.3390/jfb12020038
- I see the inappropriate use of English which makes the current article presented by the authors difficult to understand. Further proofreading is needed to improve the quality of the present article. This is the fundamental reason why this manuscript needs a major revision or should be rejected.
- Describe the novelty of the article made by the author? From the results of my evaluation, it seems that there are many similar published works that adequately explain what you have raised in the current manuscript. This is the fundamental reason why this manuscript needs a major revision or should be rejected.
- The author seems to have made an error in using uppercase and lowercase in the title of the present article that should be corrected.
- For performing meta-analysis, I advise the authors to include Scopus database apart from Web of Science and PubMed that have been used in the present article.
- Figure 3 in line 227 page 10 is too large, so the figure description do not fit into one pages to the figure. The authors should reduce the image size.
- What the software used by the authors to analyse the data for performing meta-analysis ? it should be mentioned in the present article.

Reviewer 2 Report
Comments to the MS (15644990) titled “The effects of several metal nanoparticles on seed germination and seed growth, a meta-analysis” by Guo et al.
In this study authors summarize the data for the influence of several metal nanoparticles on seed germination and seed growth of plants. The study provides useful information on the influence of NPs on plant development, but some additions are needed.
The authors summarize the influence of NPs on root development. It is necessary for the authors to present data on the relationship between root development and nutrient uptake in order to justify the chosen of this parameter.
In the section “Discussion”, it is good to discuss how nanoparticles affect the process of photosynthesis, which correlates with plant yields.
It is well known that low concentrations of Zn favor the development of plants, but an excess of zinc has an adverse effect. Why only the positive effect of Zn-NPs is described in the study, as there are data in the literature showing the negative effect of these nanoparticles on plants?

Round 2
Reviewer 1 Report
After carefully reading the author's revised manuscript entitled "The effects of several metal nanoparticles on seed germination and seedling growth, a meta-analysis" (Special issue in Functional Nanoparticles for Environmental Contaminants Removal and Agricultural Application), The authors have been made significant improvements in the revised manuscript. With my pleasure, I recommend the manuscript should be accepted for publication on Coatings.
