Summary Introduction: Peppermint (Mentha piperita L.), a member of Lamiaceae family, is an important medicinal plant that has many useful properties. Copper is an essential micronutrient for normal plant growth and metabolism. Objective: The aim of this study was to examine the effects of copper sulphate and copper nanoparticles on morpho-physiological traits and essential oil composition of peppermint. Methods: Seven treatments of copper sulphate and copper nanoparticles in three concentrations (0.5, 1.0 and 1.5 g/l) and control were applied in foliar application three times of the interval of 15 days up to flowering stages of peppermint in Karaj, Iran in 2015. Results: Copper nanoparticles (1.0 g/l) increased chlorophyll content and essential oil percentage of 35% and 20% higher than control, respectively. The copper sulfate (0.5 g/l) increased dry matter yield up to 58% higher than control. The effects of treatments were significant on 17 out of 34 compositions. Copper nanoparticles (1.0 g/l) increased menthol, menthone and menthofuran content up to 15, 25 and 65% higher than in control, respectively. Conclusions: Foliar application of copper sulfate (0.5 g/l) and copper nanoparticles (1.0 g/l) in flowering stage were suggested for increase of dry matter production, essential oil content and composition, respectively.

Physical And Chemical

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.

Coriander is one of the most popular and intensely used spices owing to its multipurpose uses worldwide. It is mainly cultivated for the production of its dried seed and fresh leaves. The present study aimed to evaluate the application of compost and foliar spraying of TiO2 on the yield and essential oil composition of coriander. Two field experiments were conducted during two successive seasons; after that, the yield parameters were determined, and the essential oil of the seeds was extracted and analyzed via gas chromatography-mass spectrometry (GC-MS). Results indicated that coriander growths at both years were significantly affected by compost application and foliar application of TiO2, and a significant interaction of these two factors also occurred. Compost application at 50 m3 caused significant increments of 55% and 46% in umbels number and 75% and 64% in seed yield in the first and second season, respectively, compared with control. The application of compost to the coriander plant significantly influenced oil percentage and oil yield per ha. The maximum oil percent was recorded in control plants. Foliar application of TiO2 resulted in significant improvement in plant height, number of umbels, and seed yield of coriander as compared with control and reached their maximum values at 6 g L−1 compared with the control; foliar application of TiO2 at 2 g L−1 enhanced numbers of umbels by 22% with no significant differences between 2, 4, and 6 g L−1 treatments in the first season and by 24, 33, and 48% in the second season. Increases in seed yield accounted for 34, 43, and 64% in the first season and 21, 36, and 45% in the second season due to titanium dioxide application of 2, 4, and 6 g L−1, respectively. The maximum content of linalool (87.61%) and minimum content of estragole (0.7%) was recorded at 4 g L−1 titanium dioxide with no compost.
