dc.abstract.enEffect of heavy metal pollution on the wood structure and tracheid characteristics in Scots pine trees from flotation tailings. Numerous studies have demonstrated the negative impact of heavy metals on plants, such as inhibited growth and other physiological disturbances. However, the detailed structure of wood cells in trees exposed to heavy metal pollution remains underexplored. To address this gap, several Scots pine (Pinus sylvestris L.) trees growing on flotation tailings was selected to compare the wood structure of trees affected by severe heavy metal pollution with those from a relatively unpolluted area. Tree ring structure, wood density, and the cell wall and lumen characteristics of earlywood and latewood tracheids were analysed. It has been found that tracheid diameters and cell wall thicknesses in wood from the polluted area differed significantly from those in the control samples. The wood of trees growing on flotation tailings exhibited slightly lower wood density than that of reference trees. This might be connected with the observed thinner cell walls in latewood tracheids of pines affected by heavy metals, compared to the reference material. Overall, considerably greater variation in most measured parameters were observed for wood samples from flotation tailings than for the control samples.
dc.abstract.plCechy mikroskopowe drewna drzew sosny zwyczajnej rosnących na osadach poflotacyjnych. Wiele badań potwierdza niekorzystny wpływ metali ciężkich na drzewa, jednak szczegółowa struktura komórek ksylemu tych drzew nie została dotąd opisana sposób kompleksowy. W ramach niniejszej pracy porównano drewno drzew rosnących na terenie nieczynnego zbiornika osadów poflotacyjnych, zanieczyszczonych metalami ciężkimi, z drewnem drzew z obszaru wolnego od zanieczyszczeń przemysłowych. Do badań wybrano sosnę zwyczajną (Pinus sylvestris L.), gatunek najczęściej wykorzystywany przez Lasy Państwowe w Polsce do nasadzeń rekultywacyjnych terenów pokopalnianych. Analizie poddano szerokość przyrostów rocznych, udział drewna późnego w przyrostach, gęstość drewna oraz wymiary światła i ścian komórkowych cewek drewna wczesnego i późnego. Stwierdzono, że drewno z obszaru przemysłowego charakteryzowało się niższą gęstością, co można tłumaczyć cieńszymi ścianami komórkowymi cewek w tym materiale. Średnica światła cewek oraz grubość ścian komórkowych cewek z drzew narażonych na działanie metali ciężkich wykazywały statystycznie istotne różnice w porównaniu z parametrami drewna z terenu referencyjnego. Co więcej, w niemal wszystkich analizowanych parametrach zaobserwowano większą zmienność w próbkach pozyskanych z terenu osadnika poflotacyjnego aniżeli w próbkach kontrolnych.
