西兰花芽富含促进健康的生物活性化合物。它们的含量取决于栽培光质和温度。然而，这些影响以前是孤立地解决的。在此，研究了培养光质量[蓝色（B）、红色（R）、R和B的混合物（R+B）、R和UVA的混合物（R+UVA）]和空气温度（15、19和23 °C）的双输入对确定生长、外部质量以及子叶和下胚轴中五种主要生物活性化合物含量的影响。还评估了收获时的碳水化合物状态和采后可变荧光与最大荧光的比率（Fv/Fm）。单色光（R或B）和升高的温度下，下胚轴长度通常增加。总酚，总黄酮，和萝卜硫苷含量普遍较高，子叶相比，下胚轴。R+B处理普遍提高了下胚轴花色素苷、总酚、总黄酮和抗坏血酸的含量，而R处理则降低了花色素苷、总酚、总黄酮和抗坏血酸的含量。这些代谢产物中的子叶含量一般受B的刺激，而在R或R+UVA下则减少。温度影响代谢物含量取决于代谢物，器官和光的质量。较低的温度，R（23 °C）或R+UVA（15，19和23 °C）与采后Fv/Fm降低相关。低温培养（
Broccoli sprouts are rich in health-promoting bioactive compounds. Their content depends on both cultivation light quality and temperature. However, these effects have been previously addressed in isolation. Here, the dual inputs of cultivation light quality [blue (B), red (R), mixture of R and B (R+B), mixture of R and UVA (R+UVA)] and air temperature (15, 19, and 23 °C) on determining growth, external quality, and the cotyledon and hypocotyl content of five major bioactive compounds were investigated. The carbohydrate status at harvest and postharvest ratio of variable to maximum fluorescence (Fv/Fm) were also assessed. Hypocotyl length was generally enhanced under monochromatic light (R or B) and elevated temperature. Total phenolic, total flavonoid, and glucoraphanin contents were generally higher in cotyledon as compared to hypocotyl. Hypocotyl anthocyanin, total phenolic, total flavonoid, and ascorbic acid contents were generally enhanced by R+B, and were decreased by R. Cotyledon content in these metabolites was generally stimulated by B, and reduced under R or R+UVA. Temperature affected metabolite content depending on the metabolite, organ, and light quality. Lower temperatures, R (23 °C) or R+UVA (15, 19, and 23 °C) were associated with decreased postharvest Fv/Fm. In conclusion, low cultivation temperature (
