Phytochemical and Morpho-physiological changes lavender (Lavandula officinalis L.) in Response to different culture media
Abstract
Background: Since the essential oil of lavender (Lavandula officinalis L.) was used for the treatment of diseases related to the nervous system and rheumatism, phytochemical evaluation of this plant is essential especially in terms of cultivation and production. Objective: This study was conducted to investigate the effect of different culture media on the amount of essential components, chlorophyll content, nutrients, growth characteristics, and rooting of lavender. Methods: The experiment was done the basis of randomized complete blocks design (RCBD) in 10 treatments and 3 replications. Substrates and culture media for plant production in this study were M1; sand, M2; sand:perlite (2:1), M3; sand:peat-moss (2:1), M4; sand:vermicompost (2:1), M5; sand:perlite:peat-moss (2:1:1), M6; sand:perlite:vermicompost (2:1:1), M7; sand:peat-moss:vermicompost (2:1:1), M8; sand:vermicompost:peat-moss:perlite (2:1:1:2), M9; sand:vermicompost:peat-moss:perlite (4:1:1:2), and M10; sand:vermicompost:peat-moss:perlite (6:1:1:2). Results: Results showed that culture media had significant effect on the all characteristics of rooting, chlorophyll and nutrient content and essential oil components in lavender plants. Limonene, borneol, and camphor were the highest amount of essential oil compounds in lavender, respectively. The highest content of limonene and oxygenated monoterpenes in M1, rooting percentage and number of main root in M3, camphor and chlorophyll content and root dry weight in M5, borneol content in M8, and hydrocarbon monoterpenes in M10 were observed. Conclusion: The application of different culture media in the production and propagation of lavender in addition to changes in morpho-physiological characteristics of lavender can directly alter the properties of essential oil and phytochemical compounds.
