Background and Objective: Mycorrhizal fungi increase the availability of nutrients in the rhizosphere by producing a wide network of hyphae, phosphatase enzymes, and organic acids. The presence of free amino acids available to the plant, using wood vinegar, can reduce the need to produce these compounds in the plant to zero. The purpose of this study is to investigate the effect of wood vinegar spraying and the use of three mycorrhizal species on the essential oil properties of garden thyme.
Methods: A factorial experiment based on a randomized complete block design with three replications was conducted over two growing seasons (2021–2023). The experimental factors included three species of mycorrhizal fungi (control, seed and soil inoculation with Glomus mosseae, G. etunicatum and G. intraradices) and foliar application of wood vinegar at four levels of control, 0.5, 1 and 1.5 %.The measured traits included essential oil percentage, dry matter yield, and important essential oil compounds.
Results: The results showed that the percentage of essential oil was affected by inoculation with mycorrhiza. Foliar spraying of wood vinegar 1% showed an increase of about 110% compared to the control. Except for α-terpinene and borneol, the interaction of mycorrhiza and wood vinegar on other essential oil compounds was significant at the 1% probability level and on cineole 1 and 8 at the 5% probability level. The inoculation of mycorrhiza G. mosseae and spraying of wood vinegar 1% produced the highest amount of thymol and carvacrol, the most important compounds in thyme essential oil are thymol and carvacrol. This treatment also produced the highest p-cymene and γ-terpinene.
Conclusion: The results showed that the use of mycorrhiza, especially G. mosseae, and foliar spraying of 1% wood vinegar can increase the quantity and quality of garden thyme.
