The element iron plays a key role in plant physiology. For plant nutrition, chelated forms of iron are preferred. Therefore, in clonal micropropagation media, FeSO4 x 7H2O is usually introduced together with Na2EDTA. At the same time, other effective iron chelates with both carboxyl and phosphorus chelates are known. So far, there are few scientific studies on the effect of iron chelates complexes on blueberry plants under in vitro conditions. Therefore, studies were conducted with different iron chelate complexes in 4 concentrations on highbush blueberry (Vaccinium corymbosum L.) cv. Brigitta Blue in clonal micropropagation technology. The best results were obtained using Fe(III)-DTPA in increased (×1.5) and doubled (×2.0) concentrations, where the multiplication factor was 4.59-4.65.
