Short-day onion cultivars differ in bulb selenium and sulfur accumulation which can affect bulb pungency

The close chemical similarity of S and Se allow for antagonistic behavior between the two elements. To determine variation for Se accumulation within onions, sixteen short-day cultivars were grown under high level (2.0 mg Na^sub 2^SeO^sub 4^ per litre) and no Se treatments. Selenium accumulation in...
