Round 1

Reviewer 1 Report (Previous Reviewer 4)

This is the third time that I reviewed this manuscript. Although the authors have made efforts to improve the paper, it still requires additional revision to make it more acceptable and defensible. Many comments have not been addressed in this version.

Some specific comments:

L17: Replace “ Morphological analysis, physiological analysis including respiration rate, ethylene production and physiological weight loss were performed. Physicochemical analyses included color, firmness, titratable acidity, pH and total soluble solids in the peel and bulb.” By  “Four genotypes, locally known namely: Agüitada, Licenciada, Rumina, and Virtud, were evaluated.

Figure 1: PLEASE reformat the figure and put a clear title and description.

Reviewer 2 Report (Previous Reviewer 5)

The statistical analysis of Table 2 should be performed again. The capital letters do not coincide with the observed differences e.g. it is not possible A and F letters being together in the same mean. The authors have to explain why data from days 10 and 11 are missing form two genotypes. The same applies to Table 3.

In PCA analysis and Figure 2, why days 3 and 7 are not depicted in the graph?

LInes 401-403: this is not true for all the tested genotypes. What about those genotypes where fluctuations were recorded (e.g. Rumina, Licenciada)?

Lines 429-433: this can be substantiated by providing fruit dry weight at the tested storage days.

Based on the results, a conclusionary sentence where the bast performing genotypes are identified, depending on fruit quality after storage, should be added in the Conclusions section.

Response to Reviewer 2 Comments

Dear reviewer 2:

Point 1: Some specific comments:

The statistical analysis of Table 2 should be performed again. The capital letters do not coincide with the observed differences e.g. it is not possible A and F letters being together in the same mean.

Statistical analysis was reviewed and tables were corrected.

The authors have to explain why data from days 10 and 11 are missing form two genotypes. The same applies to Table 3.

On lines 199-202 and 248-251 it is explained why data from days 10 and 11 of two genotypes are missing.

In PCA analysis and Figure 2, why days 3 and 7 are not depicted in the graph?

As there are several correlated variables, it was decided to use principal component analysis (PCA) in order to reduce the dimensionality of the data. And one of the requirements to increase the explanation of the principal component is to introduce data with high variability, in this way the PCA will allow to find a pattern in the data and correlate them with each other, allowing to give a greater explanation of the behaviour of the values; because there was not much variability between days 1-3, 3-5, 5-7, 7-9 and 9-11 it was decided not to analyse the intermediate days (3 and 7).

Lines 401-403: this is not true for all the tested genotypes. What about those genotypes where fluctuations were recorded (e.g. Rumina, Licenciada)?

The behaviour described in relation to RR and physicochemical parameters (TA and TSS) is representative in climacteric fruits. However, as observed in the results, the same behaviour may not occur between genotypes. This can also be attributed to other organic compounds that act as substrates for respiration (fatty acids, amino acids, ketone bodies).  This can also be related to the regulation of genes expressing enzymes that regulate metabolic pathways related to respiration. For example, phosphoenolpyruvate, ATP and NADH inhibit phosphofructokinase (PFK). In another section of glycolysis, phosphoenolpyruvate to pyruvate is regulated by pyruvate kinase, being activated by adenosine diphosphate and inhibited by adenosine triphosphate. Finally, this is evidence of physiological differences in the evaluated genotypes of jackfruit.

Lines 429-433: this can be substantiated by providing fruit dry weight at the tested storage days.

The dry weight was quantified but only of the bulbs or pulp of the jackfruit and no statistically significant differences were observed in this parameter during storage, which can be seen in the following table.

General points: authors must present the results in several paragraph for each section according the vegetal material part such as leaf, bulb etc. they also should use a transition word to make the manuscript understandable.

recommendation followed throughout the text

 

3.1. Morphological Analysis

Line 128: “Agüitada” and “Licenciada” differed from the rest of the genotypes. What are this sentence used for?

It refers to the fact that the genotypes mentioned are different from the rest in the evaluated parameter; and it was written in lines 139-144.

 

Line 129-130: The LPE had a maximum value of 33.24 cm for “Rumina” and was statistically equal 129 to “Virtud”. “Licenciada” had a minimum value of 19.22 cm for LPE. “must be improved as Regardong LPE, Rumina and Virtud gave the highest value (..cm) while the lowest value was found with Licenciada (.. cm).

Line 136: remove “the rest ... similar” because “only” already mention it.

Restructured from lines 139 to 171

Line 138: “Agüitada” and “Licenciada” were similar (in RW) and “Agüitada” and “Virtud” 138 were also similar (in RW) must be improved. Restructured from lines 139 to 171

 

Line 139-142: however “Rumina” and “Licenciada” showed the highest values for BW (5.4 and 4.58 kg, and BWI (......) respectively, while “Agüitada” and “Virtud” were similar for both genotype. Restructured from lines 139 to 171

 

Line 142: As far as concerning NSPF, not significant difference was found, however, Rumina” showed the highest value (130.33 seeds).

Restructured from lines 139 to 171

 

Line 148-149: Authors should firstly indicate if the difference is significance before showing la lowest or highest. If the difference is not significance, it is not necessary to explain this difference.

Restructured from lines 139 to 171

 

Line 150-151: Authors need to give the reference

Restructured from lines 139 to 171, references L:144

 

Line 151-154: idem as line 148-149.

Restructured from lines 139 to 171

However, it is considered that the wording in this part is correct since it is mentioned that the only genotype that has significant differences is the "Agüitada" genotype.

3.2. Physiological Analysis

Line 159-160: The RR” was 53.16, 41.53 and 31.74 mL of CO2 kg−1·h−1 for “Agüitada, Virtud”and “Licenciada” respectively. Review attended L:178

Review attended L:199

 

Line 182: what was the duration of storage of authors 12 and 13?

In the article by Mata-Montes de Oca et al. 2007 [12] it was 10 days of shelf life at 20 ± 1 ºC and 85 ± 5 % RH and for Morelos-Flores et al. 2021 the shelf life of jackfruit was 8 days at 25 ± 1 ºC and 85 ± 5 % RH.

Included in L:200-202

Line 183-184: what authors mean by “an acceptable percentage was obtained for these fruits”? When comparing the results obtained in this research with those obtained by authors 12 and 13, we observed a decrease in FWL; therefore, we report this parameter within the range and consider it acceptable for jackfruit.

3.3. Physicochemical Analysis

Line 186-187: from Table 2, physicochemical analyses including bulb color (BC), peel firmness (PF), and TA showed significant differences (P ≤ 0.05).

Review attended

 

Line 188-193: Authors jump from BC, PF and TA to PC which is not mentioned before. In addition, authors must organize the paragraph from the first day to the last day.

Restructured from lines 205-211

 

Line 194-196: On what basis authors divized the genotype in 2 groups? They have to explain this in this section.

Based on the color of its pulp (orange and yellow); L:215

 

Line 194-203: How could authors relate hue value to the color? Authors could indicate the percentage of loss of hue value and explain why?

The data obtained from BC were reported in the LCH system, in which L is set as lightness, C represents saturation and Hue is the hue angle. The °Hue allows us to find the variation of hue in a specific color, thus being able to correlate the increase of this value with the generation of phytochemical compounds such as alpha and beta carotene in jackfruit, these compounds produce yellow and orange coloration respectively; research already conducted with jackfruit reports only °Hue values to express these results (Mata-Montes de Oca et al., 2007 and Morelos-Flores et al., 2021).

Part of this, it has been included from line 223-228

Review attended and text restructured L:246-250

 

3.4. Principal Component Analysis

This section should be rewritten. The paragraph is not comprehensive. The authors should first specify the different projections they make and then relate the variables to the projection because on the figures some scripts are unreadable. What authors mean by “the fruit L/W ratio, seed L/W ratio, PC, BC, and PF did not present important changes” and the pH, BF, leaf L/W ratio, and RR decreased in this analysis? How can PCA indicate a decreasing or increasing state of a variable?

This review was addressed and the principal component analysis section was rewritten

 

The variable projections on the PCA depend on the representativeness of the variable. When the variable is on the circle, it means that its projection is good and not high or low conversely.

Review attended and text restructured L:258-305

 

Why do the authors state in the results section that larger fruits will have a lower RR and L/W ratio? Authors should present the figure so that we can understand the data connection between them. Review attended and text restructured L:258-305

In this section, Authors indicate Y axis which is not shown in any Figure 3. Authors should relate Figure A, C, D with their opposite B, D and E for better comprehension. Review attended and text restructured L:258-305

How can PCA 2 affect the variable values?  Review attended

Table 1: No WP find in tis table. This was a drafting error, it was not the abbreviation WP but WS. Corrected

  1. Discussion

Authors should define each abbreviation at the beginning of each section. In addition, authors are not working on the change of parameters but on the comparison of these parameters between 4 genotypes. Therefore, they have to link their explanation to this objective.

With regard to the commentary on abbreviations, these are defined in the body of the manuscript the first time they are used and then only referred to.

The discussion focuses mainly on the behaviour with respect to the different genotypes as this is the effect, which in the objective is of interest; with respect to the variability of the parameter itself with respect to time although it is seen, it is to a certain extent predictable that the days of storage would affect it, therefore there is more interest in the analysis between the genotypes.

 

4.1. Morphological Analysis

Authors should structure the paragraph according to each variable

Review attended

Line 317: what authors mean by” Different figures were reported by Ibrahim et al. [17]” and WP? Review attended and supplemented text L:318-322

Line 321: What is TP ? Tickness of the peel, is indicated in line 83

Line 339-344: this paragraph should be written as “Of the above-mentioned, there is statistical evidence that variability between the jack-fruit genotypes is evident in the parameters evaluated in this research (Anu et al. [23], Mitra & Maity [24], Rahman et al. [25], Rai et al. [26], Reddy et al. [27], and Singh 343 et al. [28]). This variability in the morphological attributes of fruits, especially in jackfruit, could be due to cross-pollination and different agroclimatic conditions, resulting in new variability [9]”. Review attended

L340-345

4.2. Physiological Analysis

Line 350: Who or what...”in the same state and the same country” are they referring to? Review attended and text restructured L:356-359

Line 346-356: Authors should structure the paragraph as: Respiration definition and goal, then compare their results to the literature and finish by the explanation of the variability. Besides, Authors should provide an explanation for the significant difference found in his study concerning EP based on the literature. Review attended and text restructured L:347-352 y L:356-359.

The EP data were correlated with those obtained in RR as mentioned in the literature. This is mentioned in lines 380-382.

374-380: Fruits produce ethylene through a biosynthetic pathway in which methionine is converted to 1-aminocyclopropane-1-carboxylic acid (ACC) and then to ethylene. In this pathway, the enzyme ACC oxidase (1-aminocyclopropane-1-carboxylic acid oxidase) is responsible for the transformation of ACC to ethylene in the last stage of this cycle. ACC oxidase activity is inhibited by CO2 ions, µ-aminoisobutyric acid and temperatures above 35 °C, and is highly oxygen-dependent.

Moreover, RR and EP can’t have a behavior. This is not proper English. The word was changed to values

Line 368-384: Authors should provide an explanation for the significant difference found in his study concerning EP based on the literature. The EP data were correlated with those obtained in RR as mentioned in the literature. This is mentioned in lines 380-382.

ACC oxidase activity is inhibited by CO2 ions, µ-aminoisobutyric acid and temperatures above 35 °C, and is highly oxygen-dependent.

 

Line 385-391: idem As no significant statistical differences were obtained, these results are attributed to the structure of the jackfruit, which can be theorised to be the same.

4.3. Physicochemical Analysis

Line 393-396: the sentence is very long and therefore incomprehensible. For what respectively is used for? Review attended and text restructured L:392-400

Line 393-401: why is there a significant difference between the genotype studied? Also, this paragraph must merge into one. An editing error was detected in the table and the Hue values at the end of shelf life indicate that there are no significant differences between the genotypes. Therefore, the discussion focuses on why the change in fruit skin colouring occurs.

Line 402-405: Authors must indicate the HUE value which will be related to the color, not the opposite. Review attended L:403-408

Line 405-409: the sentence is long. Review attended

Line 402-414: Same observation for BC. See Comment for the Line 393-401. Review attended and text restructured L:392-400

Line 416-437: Idem, See Comment for the Line 393-401. Review attended and text restructured L:392-400. In the sections indicated, the reasons for the physico-chemical changes of these variables are discussed, where it is implied that they will be dependent on the ethylene production, respiration and enzyme activity of each genotype.

Conclusion

Is Authors measure the content of bulbs? The number of bulbs was counted, however they were not reported in this manuscript. This was a typing error
What authors mean by “ the most CO2”? Review attended
Line 444-447: this sentence is confusing. Review attended and supplemented text

Reviewer 2 Report

This manuscript focused on jackfruit genotypes. But the paper just like a popular science article. The quality of figures are low, just like Fig. 1, there were no ruler in the figures, and the labels under the fruit could not be seen clearly. And the respiration rate were too high, I think this data may be have some problems.

Author Response

Este manuscrito se centró en los genotipos de jackfruit. Pero el documento es como un artículo de divulgación científica. 

La calidad de las figuras es baja, al igual que la Fig. 1, no había regla en las figuras y las etiquetas debajo de la fruta no se podían ver claramente. The photos of fruits and leaves could be relabelled, but the authors would like to propose to the editor to consider the digital photos as accompanying material so that they can be clearly seen when enlarged.

Y la tasa de respiración era demasiado alta, creo que estos datos pueden tener algunos problemas. Jackfruit is a fruit with a high respiratory rate and high ethylene production concentration, which is supported in other publications (Mata-Montes de Oca et al., 2007; Morelos-Flores et al., 2021) related to RR and values close to those found in our research are reported.

Lines 313-344: In the Discussion on morphological analysis of genotypes, there is no summary that would tell what significance these features have from the point of view of the cultivation of this species. Especially those whose value differs from previous measurements obtained by other researchers.

This research is making an incursion in obtaining morphological data that will characterise the genotypes of yaca in the country, due to the fact that there is little or no information on these parameters, which is of utmost importance because it will give elements to start with the processes of registration of varieties for the protection of these fruits

In the conclusions, I lack some general summary that would show how significant these results are and which ecotypes from the subjects will be important growing in the cultivation of jackfruit in Mexico. The recommendations that the authors could give for production would also be valuable. The analyses carried out revealed that the Rumina and Licenciada genotypes are the ones that can be handled mainly as export fruits. Furthermore, the characterisation of the four genotypes studied may allow the registration and protection of these fruits that have been developed in the region.

Reviewer 4 Report

INTRODUCTION:

The introduction section needs to be more developed; the authors should add some information about the effect of climate, soil and cropping systems on Jackfruit physicochemical morphological features. It is also of great interest to report information about the functional, medicinal, and therapeutic qualities and benefits of jackfruit. And link such information with the genotypes/varieties….

L33 “Due to its edaphoclimatic adaptability, ….. characteristics of the fruit.” L38, should be moved to the last part of the introduction L54.

Reviewer 5 Report

In the present manuscript, a morphological, physiological, and physicochemical characterization of four jackfruit genotypes cultivated in Mexico was performed.

Introduction is too short. More information is needed regarding the species and the studied parameters.

The statistical analysis in Table 2 should be performed with a two-way ANOVA (storage time x genotype).

Figure 2 should be replaced by a Table with the proper statistical analysis. On what basis is expressed the weight loss (fresh or dry weight)?

Figure 3: a multivariate analysis with two factors should be performed.

In the present manuscript, a morphological, physiological, and physicochemical characterization of four jackfruit genotypes cultivated in Mexico was performed.

Introduction is too short. More information is needed regarding the species and the studied parameters. Review attended

The statistical analysis in Table 2 should be performed with a two-way ANOVA (storage time x genotype). A single factor analysis was used because the aim of the research is to study the differences between genotypes and not the effect of days of storage on the jackfruit.

Figure 2 should be replaced by a Table with the proper statistical analysis. On what basis is expressed the weight loss (fresh or dry weight)? The physiological behaviour of the fruit is usually reported by means of graphs as Mata-Montes de Oca et al. (2007), Morelos-Flores et al. (2021), Vargas-Torres et al. (2017), because it is easier to visualise the fruit respiration behaviour and the appearance of the climacteric peak.

Regarding the PWL, it is taken from whole fruit and the difference in weights during storage from one day to the next.

Figure 3: a multivariate analysis with two factors should be performed. The main interest of this research was to find differences between four genotypes of yaca from the state of Nayarit, not the effect of storage days. Therefore, it was only important to evaluate the morphological, physiological and physicochemical characteristics of the four genotypes in the initial, middle and final days of their storage life.

Reviewer 5 Report

The authors provided their responses to my comments. However, the manuscript still needs to be revised before it is suitable for publication. 

Introduction is too short. More information is needed regarding the species and the studied parameters.

Response: Review attended

New comment: the introduction is still too short. Some more details about the postharvest physiology and how they affect quality of jackfruit or similar fruit would be useful.

 

The statistical analysis in Table 2 should be performed with a two-way ANOVA (storage time x genotype).

Response: A single factor analysis was used because the aim of the research is to study the differences between genotypes and not the effect of days of storage on the jackfruit.

New comment: If the aim was only to characterize the genotypes why you performed a storage experiment? You should present only the results related to characterization.

Figure 2 should be replaced by a Table with the proper statistical analysis. On what basis is expressed the weight loss (fresh or dry weight)?

Response: The physiological behaviour of the fruit is usually reported by means of graphs as Mata-Montes de Oca et al. (2007), Morelos-Flores et al. (2021), Vargas-Torres et al. (2017), because it is easier to visualise the fruit respiration behaviour and the appearance of the climacteric peak. Regarding the PWL, it is taken from whole fruit and the difference in weights during storage from one day to the next.

New comment: You should try to visualize the statistical differences (using asterisks or Latin letters). Regarding the PWL, what was the basis of weight calculation? The physiological loss implies weight losses due to respiration and consumption of solids, which different from weight loss due to transpiration.

 

Figure 3: a multivariate analysis with two factors should be performed. The main interest of this research was to find differences between four genotypes of yaca from the state of Nayarit, not the effect of storage days. Therefore, it was only important to evaluate the morphological, physiological and physicochemical characteristics of the four genotypes in the initial, middle and final days of their storage life.
