The aim of this study is to examine the effect of arbuscular mycorrhizal fungi (AMF) colonization on biomass, polyphenol profile, and content of economically important herbs. A pot experiment was performed with marjoram, lemon balm, and marigold applying a commercially available AMF mixture for inoculation. Major polyphenols were identified using HPLC-UV-ESI-qTOFMS on the basis of their UV-vis and mass spectral characteristics, and selected ones were quantified. We showed that AMF can provide different services for each herb. Marjoram had the highest level of fungal colonization (82 M%) followed by lemon balm (62 M%) and marigold (17 M%). AMF inoculation significantly increased the biomass of marjoram (1.5-fold), the number of marigold flowers (1.2-fold), and the yield of rosmarinic acid and lithospermic acid isomers of marjoram (1.5-fold) and lemon balm (1.2-fold). Therefore, the quantity and quality of plant material could be improved by the application of optimized AMF inoculum.
本研究旨在考察丛枝菌根真菌（AMF）定殖对重要经济草本植物生物量、多酚谱及含量的影响。采用市售AMF混合物接种，对马郁兰、柠檬香蜂草和万寿菊进行盆栽试验。根据紫外可见光谱和质谱特征，采用HPLC-UV-ESI-qTOFMS鉴定主要多酚，并对选定的多酚进行定量。我们发现，AMF可为每种草本植物提供不同的作用。马郁兰的真菌定殖水平最高（82 M%），其次是柠檬香蜂草（62 M%）和万寿菊（17 M%）。接种AMF显著增加了马郁兰的生物量（1.5倍）、万寿菊的花朵数量（1.2倍），以及马郁兰和柠檬香蜂草中迷迭香酸和紫草酸异构体的产量（分别为1.5倍和1.2倍）。因此，应用优化的AMF接种剂可提高植物材料的数量和质量。
