Abstract/OtherAbstract:
BACKGROUND: Among berries strawberry fruits are one of the richest natural sources of health beneficial components as micronutrients, antioxidants and phytochemicals. Strawberry quality varies greatly upon genotype, environmental factors, cultivation techniques and nutrient supply. The study aimed to assess the influence of phosphorus (P) and iron (Fe) deficiency on the bioactive compound content in strawberry fruits grown in hydroponic conditions.
RESULTS: Different nutrient supply clearly influenced the qualitative parameters of strawberry fruits. Principal component analysis (PCA) showed that three homogeneous clusters could be identified. The three treatments (control, iron deficiency and phosphorus deficiency) differed especially because of their phenolic compounds and antioxidant potential, being the strawberry fruits grown under Fe and P deficiency richer in pelargonidin-3-glucoside, benzoic acids and flavonols than the control fruits.
CONCLUSION: Nutrient deficiency had a positive effect on nutritional and health parameters of strawberry fruits without impairing fruit yield and quality parameters as acidity, firmness and total soluble solid content. This effect is strongly correlated with the specific nutrient missing in the growth medium, e.g. either iron or phosphorus. The shaping of nutrient availability in the growing medium could thus be of help in producing edible yield with desired qualitative aspects and nutritional value.
