Efecto de la contaminación ambiental sobre las superficies foliares de Pinus nigra de Els Ports (Castellón)

Possible alterations caused by air pollution in the wax structures of Pinus nigra needles, growing in 'els Ports' location (Castellón), have been examined by scanning electron microscopy. Our results show that the percentage of structurally functional epistomatic chambers decrease with needle age, being the adaxial surfaces preferently eroded. Structural alterations of epistomatic waxes in needles from trees growing in this area are greatly enhanced in comparison to controls.
