摘要:
以奶油生菜为研究材料，在植物工厂人工光源中设置3种紫外线B(UV-B)剂量［0、8.64、17.28 kJ/(m2·d)］处理，利用广靶代谢组学技术，分析不同剂量UV-B辐照下生菜叶片中的差异代谢物质，研究UV-B辐照对生菜生物量、光合参数和次生代谢物的影响。结果表明，与0剂量相比，低剂量UV-B处理对生菜生物量、光合参数均未产生显著影响，代谢组检测到30种差异代谢产物，主要为生物碱、酚类、萜类等物质，其中9种上调表达，21种下调表达；高剂量UV-B处理显著降低了生菜地上部干重、地下部干重、气孔导度和蒸腾速率，但地上部鲜重、净光合速率均未呈现显著差异，共检测到35个差异表达代谢物，其中21种上调表达，14种下调表达，上调表达的代谢物主要为黄酮类、单萜等，生菜叶片槲皮素含量在低剂量、高剂量UV-B处理下均显著增加。研究结果可为利用UV-B辐照提高设施生菜营养品质提供理论依据和参考。
