Sažetak
Functional food such as fruits and vegetables, gained much interest due to beneficial impact on human’s health - reduced risk of chronic, degenerative and of oxidative stress mediated diseases, such as cancer, cardiovascular and neurodegenerative diseases. The strawberry (Fragaria x ananassa Duch.) fruit generally possesses a high level of antioxidant activity that can be related to total phenols content, to high vitamin C content or both. In this research the effects of biostimulators (Viva and Megafol) and reduced fertilization level on the productivity and fruit quality of soilless grown strawberry cultivar Elsanta have been investigated, during two fruitbearing seasons. The tested fruit quality parameters were the total antioxidant capacity (TAC), total ascorbic acid (AA), total anthocyanins (AC), total phenolics (PHE) and nitrates (NO3) content. Our results indicated a stimulating effect of a combination of biostimulators but only in the second year of fruitbearing (the spring experiment), where plants treated with both Viva and Megafol gained the highest yield. In the first year of fruitbearing (the fall experiment), at reduced rate of fertilization, total phenolics content in strawberry fruits was significantly higher while nitrates content was significantly lower which is of particular importance for its nutritional value.
