Popis: International audience; Composition of Helichrysum italicum subsp. italicum essential oil showed chemical variability according to vegetation cycle, environment and geographic origins. In the present work, 48 individuals of this plant at different development stages and the corresponding root soils were sampled: (i) 28 volatile components were identified and measured in essential oil using GC and GC/MS; (ii) 10 elements from plants and soils have been estimated using colorimetry in continuous flux, flame atomic absorption spectrometry or emission spectrometry (FAAS/FAES); (iii) texture and acidity (real and potential) of soil samples were also reported. Relationships between the essential oil composition, the inorganic plant composition and the soil characteristics (inorganic composition, texture and acidity) have been established using multivariate analysis such as Principal Component Analysis and Partial Redundant Analysis. This study demonstrates a high level of intraspecific differences in oil composition due to environmental factors and more particularly soil characteristics.
