摘要： 以红甜菜为供试材料,调控不同LED的蓝光(450 nm)与UV-A(400 nm)的强度比,紫外光(UV-A)与蓝光(B)比例分别为0∶50(T0)、5∶45(T5)、10∶40(T10)、15∶35(T15)、20∶30(T20)处理,统一总光强为50μmol·m-2·s-1,以研究蓝光耦合UV-A对红甜菜营养品质的影响,为工厂生产功能性蔬菜提供照明策略参考.试验结果表明,蓝光耦合UV-A对红甜菜的生物量、可溶性糖、硝酸盐和维生素C无显著性影响;T5处理的类黄酮含量最大,较对照增加了14.99%;T10处理的游离氨基酸含量最高,较对照增加了58.19%,在T15时,红甜菜的叶绿素含量和花色苷含量最高,较对照分别增加了33.33%和17.34%.T15处理可以作为提高红甜菜色素的光照方案.
