A field experiment was conducted from 1989 to 1991 on a Fox loamy sand soil to study the effects of harvest date on selected agronomic, physical and chemical characteristics of peppermint (Mentha piperita L.). Plant biomass and essential oil yields increased throughout the season to a maximum in very late August to early September. Menthol, neomenthol, and menthyl acetate concentrations increased in the essential oil with plant development. The amount of menthone and isomenthone was highest in immature plants. The concentrations of menthofuran and pulegone in the essential oil corresponded to the amount of flower bloom in the peppermint. Changes during the season in the concentrations of piperitone, terpinene-4-ol, α-terpineol, 1,8-cineole, limonene, γ-terpinene, terpinolene, α-terpinene, α-pinene, β-pinene, 3-octanol, β-myrcene, Linalool, sabinene, caryophyllene and Germacrene-D were typically quite small. In general, these preliminary results indicate that peppermint can be grown successfully on the coarse-textured soils of Ontario. Key words: Mentha piperita L., peppermint, essential oil, essential oil composition, harvesting date

The progress of nanotechnology presents many nanoparticles that are important in medicine, agriculture and industry. Quickly and entirely absorbed by plants, nano-compounds and remedy their nutrient deficiency and satisfy this need. Iron oxide nanoparticles with suitable surface chemistry can be used as a rich source of iron for plants due to its gradual release of Fe in a wide pH range (pH 3 to 11). The present study investigated the impact of iron oxide nanoparticles (Fe2O3NPs in 0, 10, 20 and 30  µM concentrations) on physiological parameters of peppermint (Mentha piperita) under salt stress (0, 50, 100 and 150 mM concentrations of NaCl). Fe2O3NPs caused increases in leaf fresh weight and dry weight, phosphorus, potassium, iron, zinc, and calcium contents of the peppermint under salinity stress but did not have an effect on the sodium element. 30 µM concentration of Fe2O3NP was more impressive. Lipid peroxidation and proline contents of the peppermint under salinity decreased significantly by applying Fe2O3NPs. The maximum activities of total antioxidant enzymes (I %), catalase, superoxide dismutase, and guailcol peroxidase were observed in plants treated with 150 mM of NaCl, but application of Fe2O3NPs declined these antioxidant activities. The results suggest that the appropriate concentration of iron nanoparticles could be used for stress resistance of the peppermint.

Peppermint is one of the valuable medicinal and aromatic plants with its powerful flavour and fragrance. Its leaf and essential oil are used in cosmeceuticals, foods, pharmaceutical and personal care products. It is well known that yield and secondary metabolite biosynthesis in the medicinal and aromatic plants are strongly influenced by abiotic stresses. Salinity is also one of the most important stress factors affecting plants. This study was carried out to determine the effect of salt stress on growth, essential oil content and oil constituents in peppermint plants. For this aim, three different concentrations of sodium chloride NaCl (0, 100 and 150 mM) were applied to peppermint plants. As a result of the study it was determined that all of the investigated parameters were significantly affected by NaCl applications. Shoot length, fresh and dry weights of plants and essential oil content decreased in line with the elevating level of NaCl. Besides, NaCl also caused differences in essential oil composition. Menthol and menthone, the main components of the peppermint oil, reduced significantly when NaCl concentration rose to 150 mM. Based on the results, it may be concluded that NaCl especially at high concentrations considerably and negatively affected plant growth, essential oil content and quality of the essential oil.
