Comparison of Essential Oil Content and Composition Between Field and Greenhouse Grown Genotypes of Methyl Cinnanmate Basil (Ocimum basilicumL.)

Abstract

Essential oil content and composition of basil (Ocimum basilicum L.) was compared under greenhouse and field conditions using 9 cloned methy1 cinnarnate basil lines. Essential oil content, cis-methyl cinnarnate, linalool and 1,8-cineole were significantly higher in field grown plants while trans-methyl cinnamate was significantly higher in greenhouse grown plants. Correlations between the greenhouse and field grown plants for these essential oil constituents were significant, indicating that the performance of the lines in both environments was consistent, although the actual means varied. The significant differences in essential oil content and composition and consistent response of basil genotypes grown under greenhouse and field conditions demonstrates that the expression of

Phytochemical and growth responses of Mentha piperita to foliar application of biostimulants under greenhouse and field conditions

“…The essential oil content in field conditions was higher than in greenhouse conditions, meanwhile, the total amount of menthol and menthone in the greenhouse was greater than in field conditions. This is due to cool night temperatures in greenhouse that it can accelerate the conversion to menthone [6]. However, these results were consistent with results of Morales et al [4] which stated essential oil content of Ocimum basilicum L. was significantly higher in the field than in the greenhouse.…”

“…Various products of the aerial parts of Mentha species have been used for centuries as tonics, antispasmodic, anti-inflammatory agents, etc. in traditional medicine [6]. Because of these and other factors, essential oil of peppermint ranks high in the market [7].…”

Morphological characterization, essential oil composition and DNA genotyping of Ocimum basilicum L. cultivars

“…Factors which may potentially affect essential oil percentage are conditions under which plants have been grown, drying, extraction procedure and age [15,32]. For instance, essential oil compositions may differ, in the same genotype, depending on the light regime [33] or on whether plants have been grown in the greenhouse or in open field [34]. It is worth noting that plants at the growth stage (10-12 cm in height) at which they are used for "pesto" contain methyleugenol at high concentration.…”

“…Linalool is present naturally in plants, including lavender (Lavandula angustifolia Mill. ), marjoram (Origanum vulgare L.), and basil (Ocimum basilicum L.) (Mansour et al, 1986;Morales et al, 1993;Narusuye, 2005). This compound occurs in two different structurally active isomer forms chemically known as enantiomers that are chiral molecules having the same molecular formula but are mirror images of each other (Ibrahim et al, 2001).…”
