Nitrogen and phosphorus levels affected plant growth, essential oil composition and antioxidant status of lavender plant (Lavandula angustifolia Mill.)

The essential oils of Lavandula angustifolia and the Lavandin hybrids "super" and "special" grown in Greece, were studied in order to evaluate their quality as far as the correlation of their essential oil composition. The essential oil yields were determined to 4.4%, 7.5% and 8.5% in the lavandula and lavandin "super" and "special" hybrids respectively. Fifty-nine constituents were identiiied representing the 99% of the oils. The qualitative analysis of the oils was carried out by GCIMS and revealed that linalool and linalylacetate were the predominant constituents. Remarkable differences were noticed between the camphor percentages among them (11.35% and 5.03% for the "super " and "special" respectively).

Plant models offer a method to examine the efficacy of homeopathic solutions. Homeopathic Phosphorus (P) dynamizations were evaluated on the linear growth and dry biomass of Verbena gratissima, a plant native to Brazil. The yields and chemical characterization of the essential oil are also given. Plants exhibited phenotypic plasticity after the homeopathic Phosphorus treatments. The dynamization 9CH, in particular, interfered with plant growth, height, diameter of stems and total dry mass. 9CH treatment showed the highest yield of essential oil. The essential oil composition of V. gratissima varied according to the different dynamization used. Homeopathic Phosphorus provided the greatest amount of β-pinene, trans-pinocarveol, trans-pinocamphone and trans-pinocarvyl acetate in comparison with controls.

New Cultivars

Lavender, otherwise known as Lavandula angustifolia Mill., is widely used in landscaping, and its oil is a valuable raw material used in many industries. Therefore, new varieties of this plant are bred. The essential oil composition obtained from fresh flowers of thirteen new Ukrainian cultivars of L. angustifolia were analysed by GC-MS, and eighty-two components were identified. Linalool and linalyl acetate were principal constituents of all of the samples, and ranged from 11.4% to 46.7% and 7.4% to 44.2%, respectively. None of the studied samples fulfilled the requirements of Ph. Eur. and ISO 3515:2002. The main reason was a high content of α-terpineol (0.5–4.5%) and/or terpinene-4-ol (1.2–18.7%). Our results are in line with multiple researchers showing that the studied lavender oils do not comply with the industry standards despite their authenticity. We also investigated the effect of the growth year on the chemical composition of five tested cultivars grown on the same plots and noticed a considerable variability between years. The obtained experimental data did not show a significant inter-year trend for the content changes of the major components. Our results allow us to deeply characterize the new cultivars and evaluate their oil for a possible use in the industry, or to designate them for future selective breeding.
