Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThank you for invinting me to review this scientific article.
I noticed that the purpose of the study was very well presented, except for one reference in the Introduction. The objective is very clear and material and methods are detailed. The results are interesting and they allow to reach the simple and good conclusion.
I made a few comments in the text with the aim of improving the quality of the text. But these are minor issues, which do not detrack from the merit of the manuscript. I think the authors should to proceed to response my comments.

Comments 4:Do you want to say:...with the increase of red in the ratios, the morphological... |
Response 4:The results showed that with the increase of red light ratios.Thank you for pointing this out. I agree with this comment. Therefore, I have Change this sentence.You can see this on lines 17 and 18. |
Comments 5:Sorry, but respectfully, I disagree. When we say that there is a synergistic effect, we are seeing that the effect was promoted by both factors, in this case, red light and blue light, or better, when one help the expression of the other one. We cannot forget that in other red and blue light ratios we do not observed the same response, and we have the same factor. So, the best result was obtained because it was possible have the "maximum" from good contribution of red light and less "negative" effect from blue light in these characteristics. |
Response 5: These results indicated that the growth of melon seedlings could be regulated by adjusting the ratio of red to blue light, thus promoting the morphogenesis of melon seedlings. Thank you for pointing this out. I agree with this comment. Therefore, I have modified this sentence..Mention exactly where in the revised manuscript this change can be found lines 20 and 21. |
Comments 6:They are in the title. The words in the title are also index words. Please add other keywords.Cucumis melo, light spectrum or spectral composition (some possibilities) |

Comments 10:this part of the text is better written in the sequential text. There was a replicated text.;replace with multiplication sign (multiplier mark). I understand that it is unnecessary to put brackets.Did the EC of the nutrient solution reach this value with only 1/4 of the power? I do not think so.I did not understand! Sorry, perhaps a language issue. But "when the cotyledons WERE ABOUT 3 LEAVES..."orwhen plants were with cotyledons, 3 leaves and 1 heart?????

Reviewer 2 Report
Comments and Suggestions for AuthorsReview of horticulturae-3172230-peer-review-v1
An interesting manuscript with some novel results, but as is it isn’t suitable for Horticulturae. The authors must make major corrections before it may be acceptable.
I note [using Turnitin software] that some of the text is taken from a thesis, and would like to be sure that none of the information has been published elsewhere?
I have annotated the manuscript, and all comments must be addressed in any revised format of the manuscript.
Some of the major issues are mentioned below:
The use of light intensity units as μmole m-1 s-1
Lines 16 to 19 are not at all informative. The reader does not know what morphological indices and leaf structural parameters are.
Line 30 and elsewhere, a space between numeral and unit
Lines 32 and 35 mention ‘largest’ so what is the largest?!
Line 51 and elsewhere, always define abbreviations.
Line 61 and 62 are the same
Line 67-68 and elsewhere avoid repetitions..
Line 74 Latin names [including those in the references] must be in italics.
I do not understand lines 85-86.
Units for y axis in Figure 1.
Line 131 what was the spectral composition of the light, and is it sensible to measure it in light spectra other than that of the treatments??!! Discuss this please.
Line 160 and elsewhere, use ‘concentration’, and not ‘content’. Look up their definitions.
Lines 164 166 use past tense.
Table 3 and elsewhere, you need to define the treatments each time they are presented in Tables and Figures.
Lines 204 to 206. This increasing and decreasing is rather weak. So better omit or reduce the significance of your statements. And contrast with lines 312-313!!
Line 225 and elsewhere ‘Effect of what???’ And define axes.
Table 6 define the parameters.
Line 291 what is the definition of ‘fenestrated’? is it appropriate here? Probably you mean ‘pallisade’?
Line 304 what is compound light?
Line 308 define ‘phy’..
Line 304 grammar needs checking.
Line 317 define CBC.
Line 323 only if >1:1.
Some of the Discussion is simply a repeat of the results.line
Lines 375 to 379 are a bit of a repeat, and really don’t help with any understanding of the different effects of the colours of light.
Lines 389-398 details need to be completed.
References.
STANDARDISE.
Use et al if so many authors in reference [1].
A lot of attention to the lack of spaces between words
Line 448 and 457 the same journal but different formats, so standardise.
No capitals in the article title [see line 408].
Line 463 avoid repetition.
Line 471 ??!!

Response 11: Thank you for pointing this out. R90B10 light source is the optimal light source, based on which the optimal net photosynthetic rate value of plants can be determined to reflect the photosynthetic potential of plants. Our research is to cultivate better seedlings, and this measure is more meaningful.The following researchers have taken the same approach:Wang, T.; Sun, Q.; Zheng, Y.; Xu, Y.; Liu, B.; Li, Q. Effects of Red and Blue Light on the Growth, Photosynthesis, and Subsequent Growth under Fluctuating Light of Cucumber Seedlings. Plants 2024, 13, 1668.The article concludes :9R1B exhibited higher actual net photosynthetic rate.Melon and cucumber belong to cucurbitaceae crops, so R9B1 was used as leaf chamber light source to determine photosynthetic parameters. |

Response 24:Light quality regulates carbohydrate metabolism in higher plants[42]. Carbohydrate is the end product of photosynthesis and an important indicator of the photosynthetic capacity of plants [43]. The light quality of the combined red and blue ratio contributes to the carbon and nitrogen metabolism of seedlings [44].Some studies have shown that red light is the most effective light source for the accumulation of soluble carbohydrates [45], but the experimental results of melon seedlings in this study showed that increasing the ratio of red light to a certain extent had a promotional effect on the accumulation of soluble proteins and sucrose in seedlings, but too high a ratio of red light treatment appeared to reduce the concentration of carbohydrates (Fig. 3 ), it is presumed that the appropriate ratio of red and blue light to enhance plant photosynthesis.

Reviewer 2 Report
Comments and Suggestions for AuthorsReview of horticulturae-3172230-peer-review-v2
This is much improved, and most of the issues I have raised have been addressed.
However, there are still some minor issues to attend to, and I am still not convinced that the photosynthetic rates should be measured with compound light, rather it should be measured with light of the same ratio B:R as in the different treatments.
So, attend to following please [line numbers refer to the track change version I received, and by the way the line numbers referred to by the authors do not always correspond to the line numbers in their revised text! Very annoying!!]:
Line 36 wavelengths
Line 64 what is R4B2?? Define.

Response 13, not complied with. None of the Tables nor relevant Figures define for example what R:B=1:9 means. This must be done for every treatment.
Line 231 and many elsewhere, you MUST leave a space between words or word and bracket. Check especially line 70.
Line 288 you must define in words what a, b, c, and d, present…
