Much is known about the effects of specific wavelengths of light on live plants. Less is known about the effects on harvested fruits and flowers. Experiments were conducted using narrow bandwidth LED lights to test the hypothesis that discrete wavelengths can affect the accumulation of volatile compounds contributing to taste and aroma. Results demonstrated that volatiles could be manipulated in crops such as tomato, strawberry, blueberry, and petunia. The research begins to explore how postharvest ambient light conditions could be geared to improve flavor or scent of agricultural products.
