“…Previous studies directly link an increase in yields with calcium application [7]. Calcium chloride and calcium nitrate compounds have been reported to be applied in various fruits including papaya [8] and guavas. These salts are applied at varied rates and timing, mostly after physiological maturity.…”

The effect of varied calcium sources, applied at different times and rates, on the yield and calcium concentration of mango fruit were investigated. “Van Dyke” mango cultivar tree of 10 years old was sprayed with calcium chloride, calcium nitrate, easy gro and water (control). The calcium sources were sprayed at the rates of 1%, 1.5% , 2% or 0% (control) during three different stages of fruit development i.e. fruit set, 30 days after fruit set and 30 days to physiological maturity. The experiment was carried out during 2017 and 2018 seasons at Karurumo, Embu County, Kenya. This orchard has been found to have low calcium levels. These experiments were laid in a completely randomized block designs with a split, split plot arrangement replicated three times. The results indicated that spraying with calcium significantly affected the weight, breadth, number and the total weight of fruits/tree. The concentration of calcium in the fruit flesh was also significantly increased by the application of calcium and a direct relationship between calcium concentration and yield attributes was reported. Calcium chloride (2.0%) sprayed at fruit set was the most effective in enhancing the fruit weight, breadth, number of fruits and the total weight of fruits. Application of calcium at fruit set was found to be the most effective in enhancing the yield. Further investigations need to be done to determine the effect of these calcium sources on the quality of fruits and the optimal rate as there was an increase in the yield with an increase in the rates.

“…This statement was supported by the study of Maftoonazad and Ramaswamy [ 51 ], who revealed that the atmosphere composition around the fruit has a significant role in AA retention during storage. Magwaza et al [ 47 ] and Madani et al [ 52 ] added that lower C 2 H 4 production in fruits improved AA retention, which was confirmed when C 2 H 4 production was measured and revealed a low concentration in KH Nps-coated papaya.…”

This study evaluated the respiration rate of coated and uncoated (control) papayas (Carica papaya L.) with 15% of Kelulut honey (KH) nanoparticles (Nps) coating solution during cold storage at 12 ± 1 °C for 21 days. The respiration rate of the papayas significantly changed during storage, with an increase in CO2 and a decrease in O2 and C2H4, while the ascorbic acid and total phenolic content was maintained. The changes in respiration rate were rather slower for coated papayas when compared to control ones. A kinetic model was established from the experimental data to describe the changes of O2, CO2, and C2H4 production in papayas throughout the storage period. All O2, CO2, and C2H4 were experimentally retrieved from a closed system method and then represented by the Peleg model. The outcomes indicated the Peleg constant K1 and K2, which were gained from linear regression analysis and coefficients of determination (R2), seemed to fit well with the experimental data, whereby the R2 values exceeded 0.85 for both coated and control papayas. The model confirmed both the capability and predictability aspects of the respiration rate displayed by papayas coated with KH Nps throughout the cold storage period. This is supported by the differences in the stomatal aperture of coated and control papaya shown by microstructural images.

“…However, in tomatoes (Solanum lycopersicum), papayas (Carica papaya) and lemon (Citrus limon), these produces are less susceptible to chilling injury (Wang, 1994). Calcium is one of the chemical treatments used apparently to strengthen the cell walls and cell membranes in order to withstand the chilling stress in okra (Abelmoschus esculentus), papaya (Carica papaya), peach (Prunus persica) and tomatoes (Solanum lycopersicum) (Madani et al, 2016;Sohail et al, 2015). Growth regulator, such as abscisic acid (ABA) is used to alter the chilling tolerance of tissues by inducing stomatal closure, reduce water loss, and prevent chilling-induced wilting of seedlings (Tijero et al, 2016).…”

The challenge of high tropical temperature and chilling sensitive horticulture required an optimum postharvest handling to minimize the worldwide concern on the postharvest losses of tropical fruits and vegetables. To ensure the harvested produces achieves the consumer acceptability, the effect of temperature on the perishable produces along the integrated series of postharvest chain operations including harvesting, processing, storage and transportation must be crucially maintained. Even though the cooling process during the postharvest handling helps to reduce deterioration from high tropical temperature, the refrigeration storage temperature may also result in detrimental chilling injury. Quality of the produces reduced because of the development of symptoms include internal and external discoloration, abnormal fruit ripening, accelerated senescence, skin pitting, wilting, increase susceptibility to decay and loss of flavour. Optimum storage temperature for specific fruits and vegetables, temperature conditioning, intermittent warming technique, controlled atmosphere storage, chemical treatments and application of growth regulator can be applied either to retard the damaging symptoms or to increase the tolerance of the commodities towards chilling injury in order to extend fresh produces shelf life.
