H NMR and LC-MS, commonly used metabolomics analytical platforms, were used to annotate the metabolites found in potato ( L.) irrigated with four different treatments based on FA to AMD ratios, namely: control (0% AMD; tap water), 1:1 (50% AMD), 3:1 (75% AMD is 75% FA: AMD), and 100% AMD (untreated). The effects of stress on plants were illustrated by the primary metabolite shifts in the region from δ 0.0 to δ 4.0 and secondary metabolites peaks were prominent in the region ranging from δ 4.5 to δ 8.0. The 1:3 irrigation treatment enabled, in two potato cultivars, the production of significantly high concentrations of secondary metabolites due to the 75% FA: AMD content in the irrigation mixture, which induced stress. The findings suggested that 1:1 irrigation treatment induced production of lower amounts of secondary metabolites in all crops compared to crops irrigated with untreated acid mine drainage treatment and with other FA-treated AMD solutions.
使用 NMR 和 LC-MS 这两种常用的代谢组学分析平台，根据 FA 与 AMD 的比例，对用四种不同处理方式灌溉的马铃薯（ L.）中发现的代谢物进行注释，这四种处理方式分别是：对照（0%AMD；自来水）、1:1（50%AMD）、3:1（75%AMD 是 75%FA：AMD）和 100%AMD（未处理）。胁迫对植物的影响表现在 δ 0.0 到 δ 4.0 区域的主要代谢物变化上，而 δ 4.5 到 δ 8.0 区域的次生代谢物峰则较为明显。在两种马铃薯品种中，1:3 的灌溉处理由于灌溉混合物中含有 75%FA：AMD，导致产生了显著的高浓度次生代谢物，从而产生了胁迫。研究结果表明，与用未处理的酸性矿山排水处理和其他 FA 处理的 AMD 溶液灌溉的作物相比，1:1 灌溉处理在所有作物中诱导产生的次生代谢物数量较少。
