Sažetak
Strawberries (Fragaria × ananassa Duchesne) are sensitive to micronutrient deficiencies, and sensitivity varies among cultivars. Iron (Fe) and zinc (Zn) are essential micronutrients and, as components of many vital plant enzymes, play a critical role in many metabolic processes such as DNA synthesis, auxin, chlorophyll and some carbohydrate formation, respiration and photosynthesis. An innovative approach to providing essential micronutrients and ensuring their constant supply to plants throughout the fruit ripening period is encapsulation technology. Microparticles (microspheres and microcapsules) were produced using sustainable encapsulation methods (ionic gelation and polyelectrolyte complexation) and materials (biopolymers). Treatments with Fe/Zn-alginate microspheres and Fe/Zn-alginate/chitosan microcapsules were performed on the short-day strawberry cultivar 'Clery'. Plants were grown in plastic tunnels in double rows on raised beds covered with black plastic mulch and irrigated with drip irrigation near Zagreb (Croatia) in 2019. Fruits were analyzed for physicochemical properties (color and firmness, total soluble solids, and total acidity). Total fruit yield and firmness were not significantly affected by any of the treatments. All treatments affected total acidity and fruit color. All treatments significantly improved fruit sweetness compared to untreated plants. Micronutrient encapsulation is a simple, sustainable and environmentally friendly method that can ensure a constant supply of micronutrients and produce strawberries of higher sensory quality.
