Change in Biochemical Content of Strawberry During Shelf Life with Growth Regulator Treatments

The aim of this study was to determine the changes during shelf life in the organic acid and phenolic components of strawberry fruit (‘Albion’ cv.) treated with methyl jasmonate (MeJA) and 1‑methylcyclopropene (1-MCP). Fruits were kept in plastic perforated containers for 3 and 5 days under room conditions. It was determined that vitamin C content decreased on day 3 in all treatments (from 22.35 to 5.27 mg 100 g −1 ), but increased on day 5 with MeJA + 1-MCP treatment. The highest citric acid level was measured as 1468.89 mg 100 g −1 on day 3 (control) and as 1423.68 mg 100 g −1 on day 5 (1-MCP). It was seen that phenolic compound content generally decreased with MeJA and 1‑MCP interaction. Treatment with 0.25-mM MeJA increased the amount of catechin on days 3 and 5 (35.679 and 27.574 mg 100 g −1 , respectively). In addition, during shelf life, organic acid content generally increased, while phenolic compound content decreased with treatments. It was observed that the strawberry fruit quality varied according to treatments during the shelf life period.
