“…In addition, this plant is also a source of vitamin A (Gomes and Negrelle, 2015). The quality of herbal medicines depends on various decisions, mainly the correct identification of a species, crop management, and edaphoclimatic conditions (Lermen et al, 2015(Lermen et al, , 2017.

“…Inoculation of medicinal and aromatic plants with arbuscular mycorrhizal fungi (AMF) may increase plant growth and secondary metabolite production, such as essential oils. Mycorrhizal associations can improve plant nutrition, increasing water and nutrient uptake, particularly phosphorus (P) (Urcoviche et al, 2015;Lermen at al., 2017). Through improving plant nutrition, AMF inoculation usually increases plant growth (Smith and Read, 2008).…”

br (Alberton O.). AbstractCymbopogon citratus (DC) Stapf (lemongrass) has many industrial applications. Various factors affect the metabolism of this plant. Specifically, its association with arbuscular mycorrhizal fungi (AMF) increases water absorption and nutrient uptake, mainly phosphorous (P). This study aimed to assess the AMF symbiotic effects on nutrient uptake and growth in C. citratus inoculated with the Rhizophagus clarus and Claroideoglomus etunicatum AMF under different levels of P applied to the substrate. The treatments were prepared in a sterile substrate with high (200 mg kg −1 ) and low (20 mg kg −1 ) P levels, with and without AMF inoculation. The experiment was conducted in a greenhouse for six months. A 3 x 2 (3 mycorrhizal x 2 levels of P) factorial experiment in a completely randomized design (eight repetitions) was used in this study. The variables spore density and root AMF colonization, basal soil respiration, microbial biomass carbon, shoot, root and total dry mass, nitrogen (N) and P content in the plant were analyzed. No significant AMF symbiotic effects (p > 0.05) on lemongrass growth were observed for the P levels. P and N content in the shoots, and total P, increased in treatments with AMF and at the high P level, particularly in the inoculation with R. clarus. Spore density, root colonization, and microbial biomass carbon were higher with AMF inoculation. It was observed that AMF inoculation increased the content of P and N in C. citratus, but did not affect plant growth. AMF inoculation can improve soil quality and, combined with a higher P level, can increase P and N uptake by lemongrass plants, modifying the plant metabolism.

“…Stable oil composition and high amount of its active components are a market prerequisite for medicinal, spice, and aromatic plants. However, such requirements depend on the farming system and environment (Urcoviche et al, 2015;Hanif et al, 2017;Mohr et al, 2017;Lermen et al, 2017).…”

“…Plants should be well nourished and resistant to biotic and abiotic stresses. These crops should produce large amounts of biomass and medicinal substances inherent to the species without the need for supplements and/or agrochemicals (Urcoviche et al, 2015;Lermen et al, 2017). The use of soil microorganisms, as arbuscular mycorrhizal fungi (AMF), is an alternative to increase the productivity of this type of plants since AMF contribute to a better development of them (Zubek et al, 2012;Befrozfar et al, 2013;Lermen et al, 2015a, Verma et al, 2016.…”

ABSTRACT. Mycorrhizal association increases the absorption of water and nutrients by plants, and thus, affects their metabolism. This study aimed at assessing the single and conjoint effects of the arbuscular mycorrhizal fungus (AMF) Claroideoglomus etunicatum and soil's humic substances (HS) on the composition of essential oil (EO), its antimicrobial activity, and development of basil (Ocimum basilicum L.). The experimental design was completely randomized in a 2 x 2-factorial design (with and without AMF and HS) with 10 replications as follows: T1 -without AMF inoculation and without HS addition; T2 -with AMF inoculation and with HS (2 L/ha); T3 -without AMF inoculation and with HS; T4 -with AMF inoculation and with HS. Plants were grown in pots with 5 kg sterile soil in a greenhouse for 6 months. Then, they were harvested and evaluated for spore density, AMF root colonization, shoot dry matter (SDM), yield and chemical composition of EO as well as minimum inhibitory concentration, used to compare the antimicrobial effect of EO in nine bacteria. The addition of HS to the soil increased the spore density of AMF and SDM (P < 0.001). The AMF inoculation with and without HS increased the EO yield of basil (P < 0.001). The treatments altered the composition of the basil EO, in which a total of fourteen compounds were detected. In treatments with AMF and/or HS, linalool (28.64 to 42.94%) and estragole (27.53 to 47.17%) were the major compounds. However, in the control (without AMF and HS), eugenol (33.90%) was the major compound. The EO showed low microbial activity against bacteria Bacillus cereus, Salmonella enterica serovar typhi, Shigella flexneri, Klebsiella pneumoniae, and Xanthomonas axonopodis pathovar begoniae. AMF inoculation and HS addition could improve the development of basil, increase EO yield, alter the EO chemical composition and its major compounds, but presented low or none microbial activity against most of the bacteria tested in this study.
