Temperature and light dependence of the VOC emissions of Scots pine
International audience The volatile organic compound (VOC) emission rates of Scots pine ( Pinus sylvestris L.) were measured from trees growing in a natural forest environment at two locations in Finland. The observed total VOC emission rates varied between 21 and 874 ngg -1 h -1 and 268 and 1670 ng...
