Reviewer 2 Report

Investigation of Flower Yield and Quality in Different Color Safflower Genotypes

In the manuscript titled “Investigation of Flower Yield and Quality in Different Color Safflower Genotypes” the authors show a detailed study regarding the productivity and flowers quality parameters of different genotypes of Carthamus tinctorius (safflower) cultured in different environments (different years).

Main comments:

1.   From the read of this manuscript I am concerned about the statistical issue.

The results and conclusions are sustained in the factorial ANOVA analysis and subsequently the post hoc comparison of means. (Line 266: All data were analyzed using GLM producers of SAS and means were compared using Tukey Test at the probability level of 0.05). I think that this analysis should be conducted with a factorial ANOVA with 3 levels for each trait (Year, Genotype and, Year x Genotype, as state in lines 270-272). It is important that p values obtained for each level of analysis should be contained in each graph panel of figure 2 (or as supplemental material). This information is useful to validate the Tukey test and subsequently other conclusions exposed throughout the text. Moreover, the graph should contain standard error bars (to show the biological variability amongst replicates).

2.   Please, note that the area units used in this manuscript (Kg da-1) is not common units (at least for me). I suggest to the authors define that units or use a new one (For example, Kg ha-1).

 

3.   With data obtained for scent, fatty acid composition and others, and with the aim to test the that the genotypes are different behaviour for the traits evaluated, it will be interesting see a PCA (Principal component Analysis). This could help to disclose genotypes with specific potential uses.   

 

4.   Please, note that all supplementary material is the same of showed in the main text.

 

 

 

Minor comments:

Line 7: please change “2Isparta” by “Isparta”

Line 122: please revise the format of figure caption.

Line 142: the units are confusing. Kg da-1?

Line 153: which was the final flowers humidity?

In figure 2, panels corresponding to Dyestuff content, b* value and chrome value, Y axis should start at 0 (cero). Please, change commas by dots of Y axes.

Line 304: “However, it is obvious that the total dyestuff ratio is affected by the sowing time and air temperatures,      and other literature supports our study”. There is not data supporting this statement (an ad-hoc experiment). It could be probably that there are others environmental factor that could be influencing the dyestuff ratio? Please, clarify this statement.

 

Line  365: Please define TPC.

Line 369: Please, show the ANOVA p value for year.

Line 409: “Eight polyphenolic compounds were determined: gallic acid, chlorogenic acid, syringic, rutine, quercetin, catechin, campferol, luteolin, rosmarinic acid.” Both in the text and in the table 2 there are nine compounds described. Please, modify the sentence.

Line 420: The legend of table 2, 3 and 4 should describe with more detailed all the information contained in the table. It is important that the name of genotypes should be referenced in this legend.

Line 486-489: please, define MUFA, PUFA and revise punctuation.

Line 587: please, change “agronomik” for “agronomic”

ANOVA analysis was repeated at 3 levels for each feature and the variance analysis table was added to the text. On the other hand, graphs have been rearranged according to your and other referees' suggestions and error bars have been added to the columns.

 

  1. Please, note that the area units used in this manuscript (Kg da-1) is not common units (at least for me). I suggest to the authors define that units or use a new one (For example, Kg ha-1).

All units were revised according to the SI unit system and the incorrect ones were arranged. 

 

  1. With data obtained for scent, fatty acid composition and others, and with the aim to test the that the genotypes are different behaviour for the traits evaluated, it will be interesting see a PCA (Principal component Analysis). This could help to disclose genotypes with specific potential uses.   

 Hierarchical cluster analysis (HCA) and the corresponding Heatmap were performed using the ClustVis online tool (Metsalu and Vilo, 2015). Unit variance scaling is used for normalized and approximated data. Pearson correlation was used for distance measurements for HCA and average cluster analysis method was used over the tightest cluster first for phylogenetic relationship. To show the relationship between the measured parameters, Pearson linear correlation analysis (Heatmap correlation) was calculated using OriginPro software (version 2021, OriginLab, Northampton, MA).

Please, clarify this statement.

 “However, it is obvious that the total dyestuff ratio is affected by the sowing time and air temperatures” The literature of this state is Patane et al ., [34].

There is a typo in the following sentence. This sentence has been changed to “this literature supports our study”.

Reviewer 3 Report

 

The author analyzed the flower and dye yield of safflower genotypes with different flower colors and some physical and chemical contents of the flowers. 10 safflower genotypes, (3 red, 4 orange, 2 yellow and 1 white), were used as material. ErbaÅŸ and Mutlucan found that the differences among the  years (except for dyestuff content, dyestuff yield, b* value and total phenolic content), genotypes  and year × genotype were significant for all characteristics. They concluded that it is not possible to suggest a specific genotype for all the traits examined in this study. However, there are genotypes that have the potential to be used in food, health and cosmetics according to flower colors, agricultural characteristics and chemical contents.

In this section, we did not include the chromatogram file of each sample. The peaks in the chromatograms obtained from each sample were matched with the peaks of the standard compounds previously introduced to the device and their definitions were made.

 

- Line 213, Please mention the cause of using three methods to examine the antioxidant activity of the studied genotype.

We used 2 different antioxidant methods (DPPH and CUPRAC) in our study. There are over 10 different methods to determine the antioxidant capacity of plants. However, determination of antioxidant capacity with a single method raises doubts about the reliability of the results. For this reason, it is important to perform at least two antioxidant capacity analyzes in many studies in terms of confirming each other. The DPPH method has been used for many years and is a reliable method. The CUPRAC method, on the other hand, is a method that has been developed in 2006 and has been widely used in recent years, and its accuracy is highly accepted in the scientific world.

The concentration of a fatty acid in the chromatogram obtained as a result of GC-FID analysis was determined by the ratio of the area of that fatty acid in the chromatogram to the area of all peaks and were calculated on a relative percent basis.

 

Statistical analysis

- Mention the version of the program.

Mentioned the version of the program

 

- Please perform the correlation analysis and principal component analysis (PCA), hierarchical cluster analysis between the different studied parameters.

- Add also the correlation between parameters in both 2027 and 2018.

The mean values of examined characters of genotype were used for multivariate principal component analysis (PCA). Hierarchical cluster analysis (HCA) and the corresponding Heatmap for phenolic compounds, fatty acids and floral scent compositions of genotype flowers were performed using the ClustVis online tool (Metsalu and Vilo, 2015). Unit variance scaling is used for normalized and approximated data. Pearson correlation was used for distance measurements for HCA and average cluster analysis method was used over the tightest cluster first for phylogenetic relationship. To show the relationship between the measured parameters, Pearson linear correlation analysis (Heatmap correlation) for examined characters was calculated using OriginPro software (version 2021, OriginLab, Northampton, MA).

 

- What did you used for detection the variance ( one- way or Two- way )ANOVA?

In line with the opinions of the other referees, the statistical analysis was performed not as a combined year, but as a 3-level anova analysis (Year, Genotype and, Year x Genotype) for each feature.

Because in safflower agriculture, if the flower is harvested, at least as much as seed production can be gained. With this study, farmers and industrialists engaged in safflower farming can estimate both the amount of flowers taken from the unit area and the amount of dyestuff to be obtained from the unit area. Here, as the differences of genotypes are revealed, it will be possible to determine differences according to flower color. On the other hand, performing other chemical analyzes on the different colored flowers harvested will enable the determination of the evaluation areas of the flowers.

Reviewer 4 Report

The manuscript entitled “Investigation of Flower Yield and Quality in Different Color 2

Safflower Genotypes” discussed flower color variation and metabolic profile of safflower. However, there manuscript lacks coherence and need to be improved significantly. Some of the issues are listed below (not limited to this).

For instance

1-    The needs to be improved. Sentences with ambiguous statements appeared repeatedly in the manuscript.

Some examples are as follows

Line 42-22; According to the data of 2021 in the world, safflower cultivation is carried out in an area of 43850, 431 hectares and 631,051 tons of seeds were obtained

Line 46: droughty regions…………

Line 55-57: “It is stated that the safflower plant was known as a dye plant in 1600 BC and the linens, bandages and textiles surrounding the Mummy of King Amenhotep and other mummies were dyed with safflower flowers in the excavations made in Egypt.”

Who stated it???

These are few such examples. I suggest revising the manuscript thoroughly with appropriate language usage and avoiding ambiguous statements. Moreover, there are many grammatical mistakes also.

2-    The authors need to use appropriate scientific terminology. Some examples are below.

Line 53: what does author means by fixed oil?

Line 46: droughty regions…………

Line 68: what does secondary composition means??

Line72-72: “Conjugation of the two quinocalchone moieties results in the 72

red pigment carthamin, which is likewise unique to this matrix”

which matrix author are referring to????

Line 294: what does number of tables means here?

Line329-330: “……… as shown below”. What does this mean? Are authors referring to some table or figure?

Line 350-352: “As a result of this study, it can be suggested that the safflower plant provides a natural antioxidant effect, as well as using it as a color additive in other foodstuffs to obtain red, orange and yellow colors.”

This is not first study on safflower flower color variation. Do not use such statements. It have been previously established that natural colorants from plant sources can be and have been used in the food industry.  

Line 353-355: “This section may be divided by subheadings. It should provide a concise and precise description of the experimental results, their interpretation, as well as the experimental conclusions that can be drawn.”

I do not understand this. Authors needs to proofread their manuscript before submission.

Line 423: what does “antioxidant power” means????

These are few such examples. I suggest revising the manuscript thoroughly with appropriate language usage.

 

 

 

3-    Need to add appropriate references in introduction and discussion section.

4-    Introduction section needs restructuring (more appropriate for readers). In current form it does not represent the background of the study, instead provide a random information.

5-    The authors have use data of two years and only calculated mean differences. Appropriate data analysis is also necessary to evaluate the results improve the quality of the manuscript.

The authors have mentioned RCBD design for evaluation of genotypes, however, follow up analysis are missing in the results

6-    Line 290-321: the authors have emphasized and suggested role of environment influencing the dyestuff in flowers. Although it can be true, but there is no need to expand the discussion on these results based on two-year data (which is not sufficient) of small number of genotypes. The materials are not enough to confirm the reliability of the results. I suggest ether to tone down the results or provided GxE results with appropriate number of genotypes and locations.

7-    Line 717-419: “When classified according to flower color; Generally, the gallic and rosmarinic acid contents of orange flowers are higher than the others. In terms of these two compounds, the order according to flower color is as follows; orange> red> yellow> white (Table 2)”

Table 2 does not have information regarding these colors presented in the results. Please provide sufficient information to understand the results.

8-    The manuscript need thorough revision (language and style editing, restructuring of results, toning down the conclusion)

9-    The study seems to be a screening study for understanding the flower color variation and associated metabolic profile. However, authors failed to conclude the major part of the results to present the genotype with favorable traits.

Author Response

Dear Reviewer;

 

First of all, thank you very much for your suggestions and contributions to our manuscript. I am attaching the file containing the corrections you suggested in the manuscript.

 

Kind regards

 

The explanations of the corrections I have made according to your suggestions are given below.

 

The manuscript entitled “Investigation of Flower Yield and Quality in Different Color

Safflower Genotypes” discussed flower color variation and metabolic profile of safflower. However, there manuscript lacks coherence and need to be improved significantly. Some of the issues are listed below (not limited to this).

For instance

 

1- The needs to be improved. Sentences with ambiguous statements appeared repeatedly in the manuscript.

 

Some examples are as follows

Line 42-22; According to the data of 2021 in the world, safflower cultivation is carried out in an area of 43.850, 431 hectares and 631,051 tons of seeds were obtained

According to the 2021 FAO data;
in the world, safflower cultivation is carried out in an area of 850.431 hectares and 631.051 tons of seeds were obtained. 

https://www.fao.org/faostat/en/#data/QCL

Line 46: droughty regions…………

Changed to arid regions

 

Line 55-57: “It is stated that the safflower plant was known as a dye plant in 1600 BC and the linens, bandages and textiles surrounding the Mummy of King Amenhotep and other mummies were dyed with safflower flowers in the excavations made in Egypt.”

Who stated it???

Added references

 

These are few such examples. I suggest revising the manuscript thoroughly with appropriate language usage and avoiding ambiguous statements. Moreover, there are many grammatical mistakes also.

 

2- The authors need to use appropriate scientific terminology. Some examples are below.

Line 53: what does author means by fixed oil?

Fixed oil = cake oil obtained from seed by extraction and cold press methods

 

Line 46: droughty regions…………

Changed to arid regions

 

Line 68: what does secondary composition means??

The class of primary composition contains Oil, Protein, Carbohydrate

The class of secondary composition contains essential oil and composition, phenolic compound, dyestuff mater, glycoside, tannin, alkaloid etc.

 

Line 72-72: “Conjugation of the two quinocalchone moieties results in the 72 red pigment carthamin, which is likewise unique to this matrix” which matrix author are referring to????

This literature belongs to (Yue et al., 2013)

 

Line 294: what does number of tables means here?

Changed to head number

 

Line329-330: “……… as shown below”. What does this mean? Are authors referring to some table or figure?

“Figure 2d, e, f, g, h” instead of “below” was written

 

Line 350-352: “As a result of this study, it can be suggested that the safflower plant provides a natural antioxidant effect, as well as using it as a color additive in other foodstuffs to obtain red, orange and yellow colors.”

This is not first study on safflower flower color variation. Do not use such statements. It have been previously established that natural colorants from plant sources can be and have been used in the food industry.  

It is also reasonable for us to delete this sentence in line with your suggestions.

 

Line 353-355: “This section may be divided by subheadings. It should provide a concise and precise description of the experimental results, their interpretation, as well as the experimental conclusions that can be drawn.”

I do not understand this. Authors need to proofread their manuscript before submission.

This sentences was deleted

 

Line 423: what does “antioxidant power” means????

It is an expression that indicates the high antioxidant capacity and effectiveness.

 

These are few such examples. I suggest revising the manuscript thoroughly with appropriate language usage.

  

3- Need to add appropriate references in introduction and discussion section.

The introduction and discussion section has been rearranged.

 

4- Introduction section needs restructuring (more appropriate for readers). In current form it does not represent the background of the study, instead provide a random information.

The introduction section has been reorganized.

 

5-The authors have use data of two years and only calculated mean differences. Appropriate data analysis is also necessary to evaluate the results improve the quality of the manuscript.

The authors have mentioned RCBD design for evaluation of genotypes, however, follow up analysis are missing in the results

According to your and other referees' suggestions, the statistical analysis of the data was re-done and the ANOVA table was added.

 

6-Line 290-321: the authors have emphasized and suggested role of environment influencing the dyestuff in flowers. Although it can be true, but there is no need to expand the discussion on these results based on two-year data (which is not sufficient) of small number of genotypes. The materials are not enough to confirm the reliability of the results. I suggest ether to tone down the results or provided GxE results with appropriate number of genotypes and locations.

Of course, it cannot be accepted by us that the net effectiveness of environmental effects has been revealed depending on the data of 2 years. However, in the literature used for this feature, it is emphasized that there are environmental differences in the results obtained in 2 different environments. On the other hand, the results obtained from at least 2 years of data in field studies are accepted by many journals.

 

7-Line 717-419: “When classified according to flower color; Generally, the gallic and rosmarinic acid contents of orange flowers are higher than the others. In terms of these two compounds, the order according to flower color is as follows; orange> red> yellow> white (Table 2)” Table 2 does not have information regarding these colors presented in the results. Please provide sufficient information to understand the results.

A list of genotypes has been added as a footnote to the table.

 

8-The manuscript need thorough revision (language and style editing, restructuring of results, toning down the conclusion)

The specified revision has been made.

 

9-The study seems to be a screening study for understanding the flower color variation and associated metabolic profile. However, authors failed to conclude the major part of the results to present the genotype with favorable traits.

Comprehensive explanations are given in the article and in the conclusion section according to flower color and content.

Reviewer 5 Report

1.      The introduction should be improved. In the last paragraph of the introduction you should highlight the novelty of the investigations carried out. Also mention the purpose of these investigations in detail.

2.      Materials and Methods

-        Please separate the materials from methods

-        Also mention the reagents used and their origin in a separate subchapter (first subchapter).

-        Mention the origin of the apparatus used for each determination including the city, country, etc. For example: Schiebler calcimeter (LITA ANALYTICAL, Turkey)

-        Mention also the country where the research was carried out.

-        Row 115- preferably use the term plant material

3.      As a personal opinion, the results chapter should be separated from the discussion chapter.

4.      The graphs must be explicit and contain all the necessary data. For example: Bars for the same ………….. followed by different lowercase letters are significantly different based on the least significant difference (LSD) test (p < 0.05). Bars for the same ……………followed by different uppercase letters are significantly different based on the least significant difference (LSD) test (p < 0.05).

5.      I also think these graphs should be drawn in color.

6.      Table 2: there were not significantly differences between genotypes? (statistical data are missing). Same for table 3. Also in tables, where you have no data or the content is zero, it is good to put a dash to make the data easier to read.

7.      Table 4: The unit of measurement is not mentioned. Statistical data are also missing

Conclusion: can be improved

Dear Reviewer;

 

First of all, thank you very much for your suggestions and contributions to our manuscript. I am attaching the file containing the corrections you suggested in the manuscript.

 

Kind regards

 

The explanations of the corrections I have made according to your suggestions are given below.

 

The introduction should be improved. In the last paragraph of the introduction you should highlight the novelty of the investigations carried out. Also mention the purpose of these investigations in detail.

 

  1. Materials and Methods

- Please separate the materials from methods

Material was given as subhead

 

- Also mention the reagents used and their origin in a separate subchapter (first subchapter).

The source of the reagents used is clearly stated

 

- Mention the origin of the apparatus used for each determination including the city, country, etc. For example: Schiebler calcimeter (LITA ANALYTICAL, Turkey)

Brands and models of apparatus have been added.

 

- Mention also the country where the research was carried out.

Mentioned the country where the research was carried out

 

- Row 115- preferably use the term plant material

Changed to plant material

 

  1. As a personal opinion, the results chaptershould be separated from the discussion chapter.

I'm sorry to say that it seems very difficult for us to separate this part right now.

 

  1. The graphs must be explicit and contain all the necessary data. For example: Bars for the same ……….. followed by different lowercase letters are significantly different based on the least significant difference (LSD) test (p < 0.05). Bars for the same ……………followed by different uppercase letters are significantly different based on the least significant difference (LSD) test (p < 0.05).

Added footnotes below graphics

 

  1. I also think these graphs should be drawn in color.

The graphic has been colored and error bars have been added

 

  1. Table 2: there were not significantly differences between genotypes? (statistical data are missing). Same for table 3.

According to the recommendations of the other referees (R1, R2 and R4), it was found appropriate to perform HCA analysis for these components.

 

Also in tables, where you have no data or the content is zero, it is good to put a dash to make the data easier to read.

Dash has been added to all tables.

 

  1. Table 4: The unit of measurement is not mentioned. Statistical data are also missing

All units in the article are arranged in SI units.

Reviewer 4 Report

Although authors have made significant changes in the manuscript. the manuscript still lacks basic coherence and its really difficult to follow the discussed results due to poor writing style. therefore i again suggest authors to revise/overhaul the manuscript and present you results in more coherent way. 

Previously, i have suggested some changes in writing style and results, and it is difficult to provide all the suggestions. based on provided input, authors were supposed to change their manuscript but they only provided point by point rebuttal without considering the whole manuscript. and its is still difficult to follow the results and reach any conclusion. 

Unless, the authors provide better version of their manuscript, its difficult to assess the contents of this study.
