- •
Effect of different nitrogen foliar treatments to vineyard on grape amino acid content.
- •
Proline treatment did not affect the must nitrogen composition.
- •
Phenylalanine and urea applications favoured the synthesis of the most amino acids.
- •
Regardless of the formulation, nitrogen fertilizers improved grape amino acid content.
- •
Enological interest to enhance amino acid content and a tool to improve wine quality.
