Effect of Silicone Application on the Ratio of Volatile Oil, Physical Properties and Active Substances of Mentha piperita L. Under Saline Stress Conditions

Abstract

This experiment was carried out during the 2021 agricultural season in the wooden canopy of the Department of Horticulture and Landscaping - College of Agriculture - Tikrit University to study the effect of adding two types of silicone on the properties of volatile oil, physical properties, and the active substance of the mint plant Mentha piperita L. grown under the influence of salt tension. The experiment was designed using Randomized Complete Block Design (RCBD) as a factorial experiment with two factors and with three replicates, and each replicate contains nine experimental units, each unit consisting of 3 pots; the first factor is the addition of two types of silicon oxide, in addition to the comparison factor (S0 control, S1 Silicone Nanomaterials, and S2 Silicone Normal). In contrast, the second factor is the addition of pure sodium chloride NaCl in three concentrations with control (N0 0 g.L-1, N1 0.45 g.L-1, N2 1.45 g.L-1). The study showed significant differences between the experimental factors. Silicon and sodium chloride application achieved higher values in active substances of Menthol, Menthone, cineole, limonene, Linalool, and Geraniol.
