This study was aimed to determine the effects of 24-eBL, a steroid growth regulator, on the plant growth, total phenolic content, essential oil content and composition in “Munstead” lavender cultivar belonging to Lavandula angustifolia. For this aim, 24-eBL was applied to plants at four different concentrations (0, 0.75, 1.50 and 2.25 mg/l) twice, at the beginning of budding and 10 days after the first application. The plants harvested during the full bloom period were evaluated for fresh and dry stemmed flower yields, stemless dry flower yield, total phenolic content and essential oil yield and composition. As a result of the study, 24-eBL at concentrations of 0.75 and 1.50 mg/l significantly increased the stemless dry flower yield, total phenolic content and essential oil yield per plant. 24-eBL applications also changed essential oil composition. To conclude, 24-eBL applications can be used to increase the dry flower yield, phenolic and essential oil contents in lavender plants.

Seed Oil Composition

Agronomic traits, oil content, fatty acid composition, antioxidant activity, and total phenolic content were studied on eight A. cruentus accessions cultivated in Southern Italy. A one-way ANOVA model was performed to compare accessions and the Principal Components Analysis was applied to identify patterns in our dataset and highlight similarities and differences. A. cruentus showed valuable seed yield (0.27 kg/m2, on average) comparable to the main tradition cereals used for animal feeding. Seed-oil composition showed significant differences among the accessions. Data showed a higher lipid content than most cereal grains (from 5.6 to 7.3%). Approximately 60% of fatty acids were unsaturated; linoleic fatty acid ranged from 19 to 34%, oleic acid from 29 to 36%, and alfa-linolenic fatty acid from 0.3 to 0.5%, respectively. The saturated/unsaturated fatty acid ratio ranged from 0.5 to 0.8, the hypocholesterolemic:hypercholesterolaemic ratio from 1.7 to 2.7, the Atherogenic Index from 0.38 to 0.66, the Thrombogenic Index from 0.85 to 1.48, the total phenolic content from 0.14 to 0.36 mg/g seeds, and the antioxidant activity (DPPH•) from 0.30 to 0.50. The studied seed-oil composition evidenced A. cruentus as a healthy ingredient for animal feed and consequently, as a possible substitute for traditional cereals. Accessions from Mexico and Arizona emerged for their high qualitative traits.
