This study aimed to explore the diversity, root morphology, and colonization of arbuscular mycorrhizal fungi (AMF) associated with eight medicinal plants of the Lamiaceae family. Rhizospheric soil and root samples were collected from eight species of Lamiaceae plants for AMF analysis. The results indicate that root colonization was not directly related to the number of AMF spores in the rhizosphere. However, a significant correlation was found between the percentage of root colonization and the number of AMF species present in the individual plants. The highest percentage of colonization (86.67 ± 1.92%) and the greatest number of AMF species were observed in Micromeria fructicosa, while the lowest colonization (27.67 ± 6.22%) was recorded in Mentha arvensis. The highest spore count was recorded in Thymus vulgaris (120 ± 27.01), whereas the lowest was found in Melissa officinalis (84 ± 17.20). Among the identified AMF species, Glomus was the most dominant, representing 35.7% of all AMF species across the eight medicinal plants. The maximum AMF spore density was observed in M. fructicosa and lowest in M. arvensis. The study suggests that AMF can significantly enhance medicinal plant growth by ensuring a consistent supply of nutrients and water, thereby supporting the sustainable cultivation of medicinal plants to meet the growing demand.
本研究旨在探索与唇形科八种药用植物相关的丛枝菌根真菌（AMF）的多样性、根系形态和定殖情况。从八种唇形科植物中采集根际土壤和根系样本进行AMF分析。结果表明，根系定殖与根际AMF孢子数量没有直接关系。然而，发现根系定殖百分比与单株植物中存在的AMF物种数量之间存在显著相关性。在矮小薄荷中观察到最高的定殖百分比（86.67±1.92%）和最多的AMF物种数量，而在薄荷中记录到最低的定殖率（27.67±6.22%）。百里香的孢子计数最高（120±27.01），而蜜蜂花的孢子计数最低（84±17.20）。在已鉴定的AMF物种中，球囊霉最为占优势，占八种药用植物中所有AMF物种的35.7%。在矮小薄荷中观察到最大的AMF孢子密度，在薄荷中最低。该研究表明，AMF可以通过确保营养物质和水分的持续供应来显著促进药用植物生长，从而支持药用植物的可持续种植以满足不断增长的需求。
