“…There are varied publications describing the effect of calcium on the fruit quality of different species such as apple [ 28 ], pear [ 29 ], cherry [ 30 ], grape [ 31 , 32 ], peach [ 33 ], and berries [ 34 , 35 ], among others. In blueberry, the use of different compounds containing calcium has been studied in soil applications, foliar and solution dips [ 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. The results show generally positive effects on fruit characteristics in terms of firmness at harvest and after refrigerated storage [ 14 , 44 , 45 , 46 ].…”

The firmness of blueberry is one of its most significant quality attributes. Modifications in the composition of the cell wall have been associated with changes in the fruit firmness. In this work, cell wall components and calcium concentration in two blueberry cultivars with contrasting firmness phenotypes were evaluated at harvest and 30 days cold storage (0 °C). High performance anion-exchange chromatography with pulse amperometric detector (HPAEC-PAD) analysis was performed using the “Emerald” (firmer) and “Jewel” (softer) blueberry cultivars, showing increased glucose in the firmer cultivar after cold storage. Moreover, the LM15 antibody, which recognizes xyloglucan domains, displayed an increased signal in the Emerald cultivar after 30 d cold storage. Additionally, the antibody 2F4, recognizing a homogalacturonan calcium-binding domain, showed a greater signal in the firmer Emerald blueberries, which correlates with a higher calcium concentration in the cell wall. These findings suggest that xyloglucan metabolism and a higher concentration of cell wall calcium influenced the firmness of the blueberry fruit. These results open new perspectives regarding the role of cell wall components as xyloglucans and calcium in blueberry firmness.

“…15 However, evidence regarding the effectiveness of this type of Ca source in relation to fruit quality is not conclusive, since in some cases the effect was only partial. 17,20 Given that there is great variability in the results previously reported, it would be interesting to know the impact of the foliar application of Ca(NO 3 ) 2 on the quality of the melon fruits in an aquaponics system.…”

“…Nitrogen (N) and calcium (Ca) are important in the cultivation of melon because they affect melon yield and fruit size and can also alter the texture and the sugar content. , Therefore, this synergic production system (aquaponics) must be carefully monitored, since, as Sallenave et al found, some mineral nutrients like Ca may need to be supplemented. Many studies have highlighted the role of exogenous Ca, applied both pre- and postharvest, in a wide range of species such as apple, peach, pear, and some berry fruits as well as its mitigation of the deleterious effect of salinity in peppers . Since Ca transport in plants is through the xylem, foliar sprays are frequently the best option for Ca application rather than addition to the soil.…”

We investigated the effect on melon fruits of “fish water” alone or in combination with a supplement of synthetic fertilizers in a nutrient solution or foliar application of Ca(NO3)2. These treatments were compared with a traditional soilless system with synthetic fertilizers and no reuse of the nutrient solution. The results show that the treatments with recirculation of fish water and with the foliar supplement yielded fruits of greater weight and size but with reduced lightness and lower concentrations of proteins, NO3 –, K+, and total amino acids. The supply of synthetic nutrients to the roots or leaves caused a reduction in the sugar concentrations and the antioxidant activity of these fruits. The use of fish water (alone or with an amendment) increased spermine and putrescine with respect to the traditional soilless crop management. The results for these bioactive compounds in melons should be considered for maintenance of health with age.

“…Calcium (Ca) is a nutrient used to improve fruit quality. It is commonly applied pre-harvest to extend postharvest shelf life [ 14 , 15 , 16 ]. Calcium functions include structural roles in cell walls, membrane stability, as well as chemical messenger communication between different plant organs and tissues [ 17 ].…”

Background: The firmness, weight, and size of blueberries are vital for commercial success of this crop. Fertilization is a key agronomic management practice that affects fruit quality, where calcium (Ca) plays a critical role. This study aimed to assess the impact of low levels of soil-dosed Ca in carboxylic acid form on fruit size, weight, firmness, and residual soil fertility. Methods: The study focused on two varieties of blueberries, Duke and Legacy, over two consecutive growing seasons on three commercial farms located in south-central Chile. This study consisted of five treatments, ranging from 0 to 4.0 kg Ca per hectare. Results: The highest firmness values observed for Duke were between 164 and 186 g mm−1, with size values ranging from 15.7 to 16.9 mm, and weight observations ranging from 1.60 to 1.76 g. On the other hand, Legacy showed firmness values between 163 and 173 g mm−1, with size values ranging from 16.2 to 17.2 mm, and weight observations ranging from 2.01 to 2.40 g. Conclusion: The application of low Ca rates to the soil did not impact the size, weight, or firmness of ‘Duke’ and ‘Legacy’ blueberries. There was a positive correlation between the Ca soil application and the concentration of exchangeable Ca.
