“…In V. arboreum Marshall and V. corymbosum, the use of a gel-based method (for root exposition) and pHmetry for a liquid plant growth medium did not reveal acidification in either control or conditions of iron ion deficiency [53]. Meanwhile, a decrease in pH and the release of various organic acids, such as oxalic, citric, malic, and other acids, were found for non-sterile plants of V. corymbosum [54,55] and V. myrtillus [56]. However, the sampling methods used for root collection did not allow the authors to exclude the acids' secretion by microorganisms located inside or outside the roots.…”

Phosphorus availability is a serious problem for plants growing and grown in acidic soils of bogs, poor in macronutrients. The application of phosphorus fertilizers to such soils is unprofitable because of the physical and chemical properties of these soils, where phosphate is firmly bound to organic and inorganic compounds and becomes inaccessible to plants. Plants of the Vaccinium genus both from natural stands and commercial plantations may suffer from phosphorus deficiency, so they need to have a number of adaptations that allow them to efficiently extract phosphorus. This review addresses the following issues in relation to plants of the Vaccinium genus: sources of phosphorus for plants; the release of phosphate ions from soil components; the transport of phosphate ions into plants; and the importance of mycorrhiza in supplying phosphorus to plants. Thus, we sought to draw researchers’ attention to sources and routes of phosphorus supply of plants of the Vaccinium genus and its unexplored aspects.

“…Two commercial cultivars of highbush blueberry ( Vaccinium corymbosum L.) with different characteristics were used in this study: the Al-sensitive Star (USOOPP10675P) and the Al-resistant Cargo (US 2013023926OP1). These cultivars differ in aluminum resistance, genetic backgrounds, ecological adaptations, susceptibility to diseases, and soil and environmental requirements [ 48 , 49 , 50 , 51 ]. One-year-old plants (uniform size and foliar area with 40 cm in height) were conditioned in plastic pots containing 18 L of half-strength Hoagland solution [ 52 ] for 2 weeks.…”

Boron (B) is a micronutrient crucial for the growth, development, productivity, and quality of crops. However, in areas characterized by acid soil (pHwater < 5.0) and high rainfall, soil B concentration tends to decrease, leading to insufficient supply to crops. This study was aimed at determining the optimal rate of B fertilization to enhance Vaccinium corymbosum L. performance in acid conditions. One-year-old cultivars with contrasting Al resistance (Al-sensitive Star and Al-resistant Cargo) were used. Plants were conditioned in plastic pots containing 18 L of half-ionic-strength Hoagland solution (pH 4.5) for 2 weeks. Thereafter, the following B treatments were applied foliarly: control, without B application (distilled water), 200, 400, and 800 mg L−1 of B as Solubor® for up to 72 h. Photosynthetic performance, root and shoot B levels, antioxidants, and oxidative stress were evaluated. Root and shoot B concentrations increased with the increasing B application, being higher in leaves than in roots of both cultivars. Net photosynthesis decreased at 800 mg L−1 B supply and effective quantum yield of PSII at 72 h in all B treatments. Lipid peroxidation increased in both cultivars at 800 mg L−1 B treatment. Antioxidant activity increased in all B treatments in both cultivars; while, at 400 and 800 mg L−1 B, total phenols increased in leaves of cultivar Star and decreased in cultivar Cargo. In conclusion, optimal B foliar application for highbush blueberry appears to be around 400 mg L−1 B. The appropriate B foliar application could help mitigate potential stress-induced problems in highbush blueberry cultivation. However, the optimal foliar B application should be confirmed in field experiments to help the farmers manage B nutrition.
