“…It suggests that the results of changes in plant biomass under similar ranges of copper concentration presented by many authors are similar in spite of different plants used (Mal et al 2002). Somewhat different observations were presented by Bouazizi et al (2010), who studied copper toxicity in expansion of Phaseolus vulgaris L. leaves. The presented (2007), willow growth and phytoextraction efficiency were significantly plant species dependent.…”

This work reports a part of hydroponic experiment results concerning changes in Salix viminalis L. cv. 'Cannabina' morphology and physiology under stress conditions with different copper concentration levels and verifies our earlier results about the role of different Ca/Mg ratios in trace elements' accumulation efficiency. In this part, we present the copper accumulation and changes in willow biomass. Concentration of copper in roots, rods, shoots and leaves was analyzed with flame atomic absorption spectrometry. Selected indices characterizing copper accumulation and plant biomass structure were calculated to estimate the potential of willow to remove metal from polluted solution. Our results indicate a general increase of copper accumulation by selected willow organs with increase of copper concentration in modified Knop's medium. Moreover, significant differences in copper phytoextraction between plants under different Ca/Mg ratios were affirmed (1:10 [ 4:1 [ 20:1 [ 1: 1 / 4 ).

“…In an experiment with Phaseolus vulgaris, this plant showed reduction on Fe, K and Zn ion contents in expanding leaves from seedlings exposed to 5 mg·L −1 of copper in the nutrient solution [35]. However, copper exposure affects water flux and ion path in rice (Oryza sativa) seedlings, while the excess of copper decreased the water flux of rice seedlings and copper upward transport increased steadily with time [36].…”

Brachiaria decumbens is a high biomass plant with great potential for phytoremediation of copper-polluted soils. The current study aimed to evaluate B. decumbens plants for phytoextraction and phytostabilization use in two different copper contaminated vineyard soils and a copper mining waste. Also, the macro and micronutrients uptake were evaluated after plants growth in copper contaminated soils. B. decumbens was cultivated in two vineyard soils (Inceptisol and Mollisol) and a copper mining waste for 47 days of growth in greenhouse. Then, B. decumbens's nutrient uptake was evaluated, and it's potential application in phytoremediation techniques for the phytoextraction and phytostabilization of copper contamination. B. decumbens exhibited high levels of biomass production at contaminated soils and no negative effect on macronutrients uptake was found. Copper contaminated soils affected micronutrients uptake by Brachiaria plants. This Brachiaria specie showed high potential on copper phytoextraction with accumulation of copper concentrations in the shoots and roots of 70 and 585 mg·kg −1 of dry mass, respectively, in the vineyard Inceptisol soil, after 47 days of growth. Mollisol soil and copper mining waste also exhibited high copper concentration in the biomass in the entire plant with 371 and 466 mg·kg −1 , respectively. Although Brachiaria exhibited low levels of translocation factor for copper, this specie showed high potential for copper phytoextraction on Inceptisol, Mollisol and copper mining waste with 1900, 1156 and 1363 g·ha −1 of copper, respectively. In summary, B. decumbens plants showed high potential for copper phytoextraction and phytostabilization of copper on contaminated vineyard soils and copper mining waste.

“…Free Cu ions readily oxidize thiol bonds within proteins, causing a disruption of their secondary structure (DUCIC & POLLE, 2005). Furthermore, excessive quantities of Cu may lead to leaf chlorosis and growth inhibition (BOUAZIZI et al, 2010).…”
