Fruit Concentrations of Amino Acids in Several Strawberry Cultivars in Relation to the Time of Harvest1

Abstract Fully mature fruit from 4 cultivars of strawberry ( Fragaria × ananasso Duch.) were examined for free amino acids at 3 harvest times. Aspartic acid, asparagine, glutamic acid, and glutamine accounted for 79 to 87% of the total free amino acids in these cultivars. Asparagine, the most prominent amino acid, decreased from early- to late-harvest.
