Sažetak
The olive leaf is a valuable source of different phytochemical compounds which play crucial role in plant defence against different pathogens or can be used for range of different nutraceuticals. Nevertheless, the olive cultivars can be differed by their leaf mineral or total phenolic content but possible link between them is still unequivocally established. Thus, the aim of this work was to investigate the difference in minerals and total phenolic concentrations in olive leaves of four Croatian autochthonous cultivars (Drobnica, Levantinka, Lastovka, and Oblica) and Italian Leccino as one of the most common allochthonous olive cultivar in Croatian olive orchards. The trail was selected as a completely random design (n = 3) during March pruning period in 2018. Selected cultivars had shown significant differences in leaf potassium (K), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), and boron (B) concentrations. Total phenolic concentration was significantly different between Levantinka cv. (8022 mg/100 g DW), Oblica cv. (7296 mg/100 g DW), Leccino cv. (6570 mg/100 g DW), Lastovka cv. (5844 mg/100 g DW) and Drobnica cv. (4233 mg/100 g DW) respectively. A strong positive correlation was noticed for total phenolic and Mg leaf concentrations (r=0, 72, p<0.01). Due to mineral and phenolic differences selected Croatian olive cultivars should be tested in future Mg plant nutrition trials
