Physiological Responses of Pak Choi (Brassica rapa Subsp. Chinensis) Genotypes to Salt Tolerance
Round 1
Reviewer 1 Report
Comments and Suggestions for Authors
The presented article describes the tolerance of different Pak Choi genotypes to salt stress. 24 local genotypes were subjected to 4 different salt concentrations. Effect of different salt concentrations on electrolyte leakage, maximum quantum yield of photosystem II (Fv/Fm), number of leaves and leaf were detected. It was discovered that salt treatment inhibits the growth of Pak Choi, but the suppression of growth was less expressed in the salt-tolerant genotypes compared to the weak salt-tolerant ones. These findings indicate that certain local Pak Choi accessions can be perspective for the cultivation and breeding of new varieties with salt tolerance.
The article can be published after some corrections.
1. line 16 and further.
“Through cluster analysis of electrolyte leakage data, we discovered 'IT262109', 'IT279432', and 'IT185735' as native species displaying the strongest salt tolerance.”
They are not species, they are accessions.
2. lines 94-107 repeat lines 79-92.

Reviewer 3 Report
Comments and Suggestions for AuthorsDear Authors, Congratulations on the manuscript, but I have some suggestions that I would like you to amend. I indicate these below.
The manuscript does not formally meet the requirements of MDPI. Please fix this.
The Introduction chapter needs a lot of modifications. The literature references used are adequate, but there are not enough literature references neither about the plant species itself, nor about salt stress tolerance, nor about hydroponics, nor about the results achieved with regard to the method used. The chapter is weak, a strong one requires expansion, please revise it strongly.
162-164. why are there lines in the manuscript? I do not understand.
It is not a good idea to combine the Results and Discussion chapters. Please keep these two chapters separate as separate chapters. So I don't accept that. Pay attention to coherence.
Cross-references in Figure 1 and Table 1 should be followed by Figures and Tables. It doesn't appear that way here.
Figure 1: The words Group are rewritten for the specific meaning, because it is more difficult to follow.
Conclusions: not good at all, please rewrite it. This part should be placed in the Results chapter, it should not be described here at all, but what short and long-term conclusions were reached based on the results.
Comments on the Quality of English LanguageIn several places, the English sentences need to be strongly improved.

Comments and Suggestions for AuthorsDear Authors,
thank you for your work, you fixed most of the things I pointed out. I'd like a few more small things.
Title 3 is incorrect.
Even now, the Introduction and Conclusions are short. Please expand.
