Abstract. Opencast coal mines of the Kolubara Mining Basin (Rudarski basen Kolubara), with the accompanying power plants, are constantly exposed to air pollution. Attempts have been made to mitigate the adverse impact on environment by means of biological recultivation by afforestation of opencast mines’ tailing disposal sites. Pseudotsuga menziesii Mirbel. Franco belongs to a group of species requently used for afforestation of such areas. Our studies, focused on substantiating the species’ resistance to air pollution, involved an analysis of this factor’s effect on changes in needles. The paper outlines the results of histological studies, which consisted of an analysis of diameter of needle cross-section, along with an analysis of share of diameter of certain tissues in crosssection.
Izvod. Površinski kopovi uglja Rudarskog basena „Kolubara“ sa pratećim energetskim postrojenjima su po stalnim uticajem aerozagađenja. Biološkom rekultivacijom odlagališta jalovine površinskih kopova čovek pokušava da ublaži negativne uticaje na životnu okolinu. Pseudotsuga menziesii Mirbel. Franco je jedna od često korišćenih vrsta u pošumljavanju ovih prostora. Naša straživanja su usmerena na potvrđivanje otpornosti ove vrste na aerozagađenje i u okviru njih istraživano je delovanje ovog faktora na promene na četinama. U radu su prikazani rezultati histoloških istraživanja koja su se sastojala u analizi dijametara poprečnog preseka četina kao i udela dijametra pojedinih tkiva u poprečnom preseku.
