“…These results contrast with previous studies, where these elicitor applications increase the physical parameters of the fruit as determined in this study [53][54][55]. Therefore, our results are related to the physiological state of the plant, which was more functional with elicitor applications, which may have led to higher fruit yield plant −1 , which often causes an inverse relationship with fruit physical parameters such as weight and size [59].…”

Blueberry exports that imply transport times of more than 25 d deteriorate their quality. The use of elicitors in preharvest has shown positive effects on the quality of berries such as grapes. The objective of this study was to evaluate preharvest applications (21, 14, and 7 d before harvest) of oxalic acid (OA) and salicylic acid (SA) on fruit firmness and phenolic compounds in blueberry. The treatments of 0, 2, and 4 mM OA in ‘Kirra’ and 0, 2, and 4 mM SA are in ‘Stella blue’. With the earlier preharvest application, ‘Kirra’ presented better firmness than ‘Stella blue’; however, 2 mM OA and SA in both cultivars increased fruit firmness, maintaining its weight and diameter with respect to the control. It should be noted that the treatment with 2 mM SA generated a 100% increase in polyphenolic content and antioxidant capacity (p < 0.05) in ‘Stella Blue’, with values close to 140 mg gallic acid 100 g−1 and 80 mg 100 g−1 fresh weight (FW), respectively. In Kirra, OA treatments did not have a significant impact on the polyphenol content, but 4 mM OA increased by 100% and 20%, total anthocyanin and antioxidant capacity of blueberry fruit, respectively. Based on our results, three pre-harvest applications of OA and SA during the fruit development until the beginning of ripening improve fruit firmness by up to 20% at different times of harvest.

“…[ 18 ]. Soilless cultivation has attracted increasing attention, and market demand is increasing [ 31 ]. The most important component of soilless substrate cultivation is an appropriate substrate, and the selection of the substrate is critical to the success of cultivation [ 32 ].…”

“…Studies have shown that cultivation using different substrates can have different effects on the growth and development of plants [ 31 , 32 , 33 , 34 ]. In a field experiment, four mixed soilless substrates were used for strawberry cultivation, and the results showed that strawberry plants grew most vigorously in 100% coconut coir, and the fruit yield was not significantly different from that under conventional soil cultivation [ 33 ].…”

“…The initial vegetative growth, fruit yield, and fruit weight of persimmon trees were greatly enhanced when the trees were grown in a coconut coir substrate [ 32 ]. Ortiz-Delvasto et al reported that the blueberry cultivar “Legacy” has better growth and yield after planting in a pure coconut coir substrate compared to a mixed substrate of coconut coir and peat (3:1, v / v ), and the fruit diameter was also relatively large in the former substrate [ 31 ]. In this study, the fruit weight in the FPB treatment group was greater than that in the other two groups, and the transverse and vertical diameters of the fruit were also the largest, indicating that the fruit grown in the substrate of peat and bark (1:1, v / v ) was well developed.…”

With improving living standards, traditional blueberry planting modes cannot meet commercial demands, and blueberry cultivation with soilless substrate has become a popular solution in the blueberry industry. In this study, different soilless substrate treatments were found to markedly influence fruit appearance and intrinsic quality. The fruit in the 50:50 peat/pine bark (v/v) (FPB) treatment group had the maximum single fruit weight, largest vertical diameter, and brightest color, as well as the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) value, solid-acid ratio and anthocyanin content. The fruit in the 50:50 pine bark/rice husk (v/v) (FBR) treatment group had the highest total phenol and flavonoid levels, largest drip loss value, and lowest total pectin content and firmness value. Metabolomic analysis showed that flavonoid, carbohydrate, and carbohydrate conjugate, and amino acid, peptide, and analog levels were significantly different between groups. Fruit in the FPB group had the highest sucrose, D-fructose 1,6-bisphosphate, salidroside, tectorigenin, naringenin chalcone, trifolirhizin, and galangin contents. The increase in the relative expression of phenylalanine (Phe) promoted the synthesis of fruit polyphenols in the FBR group. Our results provide new insights into the effects of different substrates on the quality of blueberries and a reference for the soilless substrate cultivation of blueberries.

“…Previous studies show that one of the most important criteria influencing the growth of highbush blueberry (V. corymbosum L.) is the pH of the soil, which must be maintained at low values (3.8-5.5), throughout the culture (Ortiz-Delvasto et al, 2023;Gallegos-Cedillo et al, 2018;Imler et al, 2019;Ochmian et al, 2021;Zhou et al, 2022). Generally, peat soils are most suitable for highbush blueberry but, currently, there is a decrease in these soils (Ochmian et al, 2019;Schreiber and Nunez, 2021).…”

Salinity is one of the most critical abiotic stresses affecting various physiological, biochemical, and molecular functions of plants. This study aimed to assess the effects of different salt concentrations on in vitro blueberry shoots (‘Bluecrop’, ‘Blueray’, ‘Brigitta Blue’, ‘Duke’, ‘Goldtraube’, ‘Hortblue Petite’, and ‘Patriot’ cultivars) and to understand the mechanisms employed by this species under saline conditions. The Woody Plant Medium (WPM) proliferation medium was supplemented with 10, 50, 100, and 150 mM NaCl to induce salt stress. After ten weeks of in vitro culture under salinity stress, various parameters were evaluated, including the number of shoots obtained/explant, shoot length, fresh weight, dry weight, water content, stress tolerance index (STI), and McKinney index (MKI). Additionally, the behaviour of blueberry cultivars under salt stress was analyzed using electron paramagnetic resonance spectroscopy (EPR). Compared to the control (culture medium without NaCl), all treatments with NaCl reduced shoot length and the number of shoots obtained/explant in all studied blueberry cultivars. ‘Brigitta Blue’ reported the shortest shoots (0.04 ± 0.02 cm) at a concentration of 150 mM NaCl, followed by ‘Blueray’ with 0.05 ± 0.03 cm. Also, the lowest number of shoots/explant was recorded for both cultivars under 150 mM NaCl, namely 0.12 ± 0.07 shoots/explant (‘Brigitta Blue’) and 0.11 ± 0.04 shoots/explant (‘Blueray’). Salt tolerance, as expressed by ITS and MKI, confirmed that ‘Goldtraube’ exhibited higher salt tolerance, with the highest ITS values and the lowest MKI values. Further validation presented ‘Goldtraube’ as the most unresolved spectra of the Mn (II) hyperfine structure under all salt concentrations, therefore ‘Goldtraube’ was the most tolerant to saline stress.
