Nickel hyperaccumulation in Blepharidium guatemalense Standl. (Rubiaceae) was found the tropical forests of south-eastern Mexico. This study aimed to document geographic extent nickel this species, understand its process and explore distribution within tissues plant. To accomplish these objectives, a complete non-destructive elemental screening herbarium specimens performed with hand-held X-ray...

Context Root foraging by hyperaccumulator plants in response to patchily distributed metals has been observed several obligate hyperaccumulators, but it is not known whether facultative hyperaccumulators respond similarly. Aims This study investigated the root-growth behaviour leguminous zinc (Zn) Crotalaria novae-hollandiae compared with non-accumulating cunninghamii localised soil Zn enrichme...

Abstract The manganese (Mn) hyperaccumulator Gossia bidwillii is a tree species native to subtropical eastern Australia where it occurs on Mn-rich soils. Here, we conducted the first Mn accumulation and tissue-level distribution study wild experimentally grown G. . plants were subjected different levels of (250 µg g −1 , 500 1000 ) soil dosing treatments, whereas was sampled from growing highly...

Different hyperaccumulator plants growing in the same contaminated soil may have excessive accumulation of different metals or produce biomass. Therefore, it is important to determine ability plant improve under natural conditions improvement heavy metal-contaminated lands with plants. This study focused on phytoremediation and biomass production capabilities Artemisa Dracunculus L. Erigeron Ca...

A phytoextraction treatment enhanced by electric field to decontaminate a heavily Pb polluted soil has been tested in a greenhouse-scale experiment. Brassica juncea was selected as Pb-hyperaccumulator plant. The influence of the application of two Electric Potential Difference values (0.6 and 1.1 V cm) and the addition of EDTA (2.5 mmol kg) on biomass production, plant uptake, contaminant leach...
