The Role of Pre- and Post-Harvest Factors on the Content of the Flavonoid Quercetin in Yellow Onion (Allium cepa)

• Three commonly-grown commercial onion (Allium cepa) cultivars in Sweden were studied in field trials performed in year 2002-2005. The role of nitrogen fertilizer source, level, lifting time, field curing, and storage on quercetin content in the onions were studied. Yearly variation in onion flavonoid content was considerable and was probably due to variations in global radiation at the end of the growing period each year.
