Biogenic emissions from Pinus halepensis: a typical species of the Mediterranean area

The determination of biogenic emissions from P. halepensis was done by the enclosure of an intact branch in a Teflon cuvette. Main emitted monoterpenes were β trans-ocimene and linalool. The total monoterpenic emission rates thus recorded were found to reach maximum values around 30 μg gdry weight−1 h−1. The normalized emission rates calculated at 30 °C and 1000 μmol m−2 s−1 with Guenther's algorithm was 14.76, 8.65 and 4.05 μg gdry weight−1 h−1, respectively, for the total monoterpenes, β trans-ocimene and linalool.
