    Abstract

    Seedlings of two common Mediterranean trees, Pinus halepensis L. and Quercus ilex L., were grown alone and together with seedlings of the same or of the other species in the same pot during one year to test the effects of intra- and inter-specific interference on terpene emission. Light, nutrients and water were amply supplied. There were higher emission rates in P. halepensis than in Q. ilex. The emission increased when the neighbour was a pine and decreased when the neighbour was a holm oak. Volatile organic compound and terpene emission rates followed inverse trends to foliar biomass or growth, which decreased when the neighbour was a pine.
