“…On the other hand, translucency is a physiological disorder affecting pineapple characterised by water soaking symptoms Chen, 2015, 2018). Field temperature, fruit sugar accumulation and low calcium levels have been determined as the critical factors related to this physiological disorder (Paull and Chen, 2018;Cano-Reinoso et al, 2022). Typically, symptoms of translucenc y appear weeks close to harvest and do not tend to increase if the fruit is handled with an adequate temperature and relative humidity during postharvest (Chen and Paull, 2017;Paull and Chen, 2018).…”

“…On top of that, lately the calcium content has been regarded as the most essential aspect to control translucency incidence (Paull and Chen, 2018;Cano-Reinoso et al, 2022). Mandal et al (2015) in their experiment employing SA after harvest with a concentration of 5 mM reduced the translucency in pineapple after more than 15 days of storage, although it was not clarified the SA impact on the calcium metabolism and enzyme related activities.…”

Salicylic acid applied pre-and postharvest can impact positively the fruit quality, although more experiments are necessary to clarify its influence on pineapple. Therefore, this study aimed to evaluate the effect of pre-and postharvest treatments with salicylic acid on physicochemical properties of MD2 pineapple. Treatments were, A (Control: Waxing but without SA application pre-and postharvest), B (SA (2 mM) preharvest (sprayed) + SA (5 mM) postharvest (dipping)), C SA (2 mM) preharvest (sprayed) + SA (7 mM) postharvest (dipping)) and D (SA (2 mM) preharvest (sprayed) + SA (9 mM) postharvest (dipping)). Fruit total soluble solids, total acidity, ascorbic acid, β-carotene, fruit weight, percentage of weight loss, firmness, respiration rate, shell colour and flesh translucency were examined. The ascorbic acid, respiration rate and flesh translucency were determined as the variables more influential in this study. Treatments with postharvest concentrations higher than 5 mM increased the ascorbic acid (˃ 300 mg/kg) and reduced the translucency incidence (˂ 20 %), while with postharvest concentrations between 5-7 mM reduced the respiration rate (˂ 12 mL CO2/kg*h). All the treatments provided ideal values for the rest of the quality variables studied. Finally, treatment C was considered the most beneficial for the fruit, delivering the most elevated ascorbic acid content (385.89 mg/kg), the lowest respiration rate (10.46 mL CO2/kg*h) and translucency incidence (16.67 %).

“…Calcium has been proved to rise the resistance of fruits and vegetables to pathogens attacks by increasing the cellular responses to biotic signals and reducing the cell wall breakdown (Madani et al, 2016;De Freitas and Resender Nassur, 2017). Concerning magnesium, this is a component of the middle lamella and also has been reported to activate calcium-dependent protein kinases (CPDKs) (Waraich et al, 2011;Huber and Jones, 2013); proteins that translated the Ca 2+ signature into specific phosphorylation events generating signaling responses as part of plant defense mechanisms (Gao et al, 2014;De Freitas and Resender Nassur, 2017;Cano-Reinoso et al, 2022b). Evidently, due to the more severe infection generated by the inject method, the fruit as a protection mechanism could have promoted the increase in the uptake of calcium and magnesium to maintain the cell wall structure, encouraging more molecular ions assimilation and enzyme activities (Ca +2 , CDPKs, respectively).…”

In this study the effect of Pseudomonas fluorescens and Trichoderma harzianum based biopesticides on fruit collapse disease incidence and pineapple quality was investigated. The experiment was implemented in a split-plot design with two factors, one involving two inoculation methods (spray and inject), and a second factor involving four treatments, A (control: no biopesticides used), B (Bio P32 from 13 weeks before harvest), C (Bio T10 from 13 weeks before harvest) and D (Bio P32 + Bio T10 from 13 weeks before harvest). The inoculated pathogen was Dickeya zeae. The incidence of fruit collapse, total soluble solids, total acidity, sucrose, ascorbic acid, mineral content, and electrolyte leakage were determined. The inject method caused more fruit collapse incidence than the spray method. Treatments C and D provided the best results having a low incidence of fruit collapse (spray: 5 and 1.7 %, inject: 20 % in both cases), high antioxidant capacity (regarding ascorbic acid), high mineral nutrient content (in terms of Ca and Mg), and low electrolyte leakage content (< 70 % in average), with a healthier cell wall characteristic. Meanwhile, treatments A and B were less efficient in these aspects and promoted the incidence of fruit collapse, especially when the inject method was used, as this was more harmful regarding the fruit physiology. In conclusion, the biopesticides employed can reduce the incidence of fruit collapse and positively affect the fruit quality.

Watercore is a physiological disorder in pineapples, which is expressed as fluid deposition in intercellular spaces and presents as water soaked. This disorder affects the fruit quality and decreases storage life, resulting in enormous commercial losses to growers and restricting the development of the pineapple industry in China. However, the molecular mechanism of watercore remains unclear. In order to elucidate the molecular mechanism of pineapple watercore, the transcriptome analyses of watercored and normal fruits were carried out in pineapples for the first time using de novo RNA-seq technology. High-quality reads of 46.66 and 43.71 M were obtained in the transcriptomes of normal and mildly watercored fruits, respectively. Clean reads of 45.50 and 42.79 M were obtained after filtering the original data. These genes are useful resources in subsequent pineapple watercore research. Fifty genes in phenylpropanoid biosynthesis, glucose metabolism, calcium transport, and cell wall metabolism were considerably different between normal and watercored fruits. Among them, the expressions of the AcPME, AcBGLU43, Ac4CL5, AcPER1, and AcPOD genes were upregulated by 7–21 times in watercored fruit, while the expressions of AcSUS7 were downregulated by 16.61 times, and the expressions of other differential genes were upregulated or downregulated by more than 2 times. A total of 38 differentially expressed transcription factors were obtained by screening. Among these transcription factors, WRKY was the most abundant, followed by MYB. The acquisition of these genes is important for the first understanding of the molecular mechanism of this physiological disorder.
