Seasonal, ontogenetical and UV-B effect on essential oil composition in Organum vulgare subsp. hirtum
1999
Kazantzis, A.
Using plant material cultivated in the greenhouse, variation in the chemical components in Origanum vulgare subsp. hirtum had been examined. The variation in essential oil content and composition can have developmental, genetical, or environmental basis. The pattern of variation for the components, in qualitative and quantitative terms had been investigated. Sampling of the plants at different seasons (spring versus summer) revealed the trends of the main and selected subsidiary components. The interconversion of the main compounds (based on percentages), could not be substantiated on their absolute content. Leaf position affects the quantity and composition of the essential oil. again, similar discrepancies were observed between interpretation of the results on the basis of concentration of the components compared to percentages. There was no positive effect of supplementary UV-B radiation in the composition of essential oil. Minor fluctuations observed were not significant.
