phytoremediation of heavy metals is employed as a technological approach for a non-destructive remediation of contaminated soils. one of the most recently studied tree species used in phytoremediation applications are poplars. in this study, the one-year old rooted seedlings of populus nigra l. used to decontaminate hexavalent chromium-contaminated soils. five treatments of cr (vi) supply (were...

abstract east azarbaijan province is one of the most important areas for poplar production and has the highest suitability of poplar plantation in iran. three species of poplar trees included populus alba, p. nigra and p. x. euramericana are planted and usually attacked by different pests in this province. melasoma populi l., archips rosana (l.) and pemphigus filaginis are some of important pes...

heavy metals are aggressive environmental pollutants. they are easily taken up by plants and they are strong stress factors for plant metabolisms. heavy metals influence includes also disturbances in plant mineral nutrition by competition with other nutrients. the specific objective of this research work was to study whether elevated cr (vi), cd and pb contamination caused an unbalanced nutriti...

  Parkinson's disease (PD) is a human neurodegenerative disorder that is associated with a massive and progressive degeneration of the dopaminergic neurons of the substantia nigra. There is strong evidence that oxidative stress participates in the etiology of PD. Therefore, we designed this study to investigate the neuroprotective activity of vitamin E, a free radical scavenger in the unilatera...

Initial seedling recruitment is one of the most critical stages for plants in the Mediterranean basin. Moreover, wildfires and post-fire environmental conditions might deteriorate regeneration success, which can lead to problems for sustainable forest restoration and forest persistence. On this context, different seed origins and pine species may be better adapted to new environmental condition...
