Abstract: Foliar nutrient sprays are broadly used in commercial agriculture. To date, the application of Ca and Si has been little explored in vineyard production but may lead to positive responses at various levels. Therefore, the aim of this work was to evaluate the effect of supplying single or combined calcium (Ca, 120 mM) and silicon (Si, 120 mM) sprays in Tempranillo grape composition. Foliar treatment with Ca + Si foliar enhanced all families of aromatic compounds, whereas single Ca and Si sprays induced lower ef… Show more

The primary challenge in red wine production is optimizing conditions for the accumulation of phenolic compounds in grape berries, crucial for the wine’s aroma, color, and flavor. With climate change impacting these components, it’s vital to study the transformation of carbohydrate-acid and phenolic complexes as grapes reach ripeness. This study focuses on the ‘Bastardo Magarachskiy’ grape variety and the effects of foliar mineral fertilization (NTP-Sintez LLC, Belarus) during ripening. Our findings show that experimental processing schemes enhance sugar accumulation in the berries by 1-4 g/100 cm3. The total anthocyanin potential ranged from 1187 to 1684 mg/dm3, with maximum extraction efficiency (61-65%) occurring at sugar concentrations of 21-23 g/100 cm3. Higher sugar levels led to reduced extraction efficiency. The phenolic profile was dominated by flavan-3-ols and anthocyanins, comprising 82.7% to 96.3% of total phenolics. Throughout ripening, there was a significant increase in the mass concentration of primary phenolic compounds in the berries, highlighting the importance of monitoring these changes for optimal wine production.

Foliar calcium (Ca) treatment exhibits strong potential for enhancing yield and quality in some fruit crops. This study aimed to assess the impact of foliar application of Ca-organomineral (Ca-OM) suspension on total soluble solids (TSS) and Ca dynamics in leaves and berries across five red currant cultivars during the vegetation and storage. A randomized block design with two treatments: (1) Control (without Ca-OM treatment) and (2) foliar Ca-OM treatment, with three repetitions, was applied on five different red currant cultivars. Although foliar Ca-OM treatments did not impact Ca or TSS in leaves, they positively influenced Ca and TSS in fruits, displaying significant variability among cultivars. In addition, Ca-OM treatment increased berry density, reduced abscission, and inhibited the development of diseases, extending storage periods for “Lvovyanka,” “Vika,” and “Gazel” cultivars by three to seven days compared to the Ca-OM untreated control. Ca-OM treatment in the early stages of the ontogenesis of currants provided a high percentage of Ca intake in berries. At the stage of complete maturation, the Ca content in berries decreased and depended on the ripening period of the cultivars. Before harvesting, Ca-OM increased the strength of berries (Fc) and reduced the shedding of berries in the clusters (Fs). At the vegetation stage, Ca-OM increased TSS in berries, and the content of TSS depended on the genotype and weather conditions. The Ca-OM treatment and low temperatures contributed to preserving berry density, reducing the shedding of berries and PLW, and restraining the development of diseases during storage. In addition, the high content of TSS and Ca in berries against the background of a slow rate of decrease in berry density in the Ca-OM variants ensured an extension of the shelf life of “Lvovyanka,” “Vika,” and “Gazel” by three to seven days compared to the control untreated with Ca-OM. Clustering analyses identified these cultivars as similar in terms of TSS and calcium content in fruits, emphasizing their common traits. The study underscores the potential of foliar Ca treatment to enhance berry quality during growth and storage, significantly improve storage duration, and fortify resistance against adverse factors, presenting promising opportunities for elevating yield and quality in specific red currant cultivars.
