The growth and development and metabolism of plants have different physiological responses to different light qualities. To study the influence of light qualities on green onions, the impacts of LED light treatment on the growth and development as well as the nutritional components and flavor substances in green onions were studied under controlled conditions. Leaf area, plant height, dry matter accumulation, Dickson's quality index (DQI), nutritional content, and volatile compounds under different light quality treatments were determined. The results indicated that the white and blue combined light (W/B: 3/1) treatment was the most beneficial to growth and nutrient accumulation and led to higher levels of sulfur compounds in the green onions than the other treatments. This shows that it is possible to control the contents of compounds that affect consumer preferences by adjusting the lighting conditions and to thereby increase the value and quality of seasoning vegetables.

LED光质组合对大葱（Allium fistulosum L.）生长及养分积累的影响比较

植物的生长发育和代谢对不同的光质有不同的生理反应。为了研究光质对大葱的影响，在受控条件下研究了LED光处理对大葱生长发育的影响以及大葱的营养成分和风味物质。测定了不同光质处理下的叶面积、株高、干物质积累、Dickson's质量指数（DQI）、营养成分和挥发性化合物。结果表明，白蓝组合光（W/B：3/1）处理最有利于生长和养分积累，并导致大葱中硫化合物的含量高于其他处理。
