“…Increased K concentration in plant samples was found for each variant and P was found to be increased on each plot treated with fertilizer, when compare to the first growing season. Gonçalves et al (2009) reported, that higher Cd concentration in hydroponic solution can decrease K uptake to above ground organs. This paper is with agreement with obtained results, however the tendency is only contrary to NPK treated plants.…”

SUMMARYHeavy metal contamination of soils is a major problem worldwide. As a result, arable land polluted with heavy metals is unsuitable for food production. Utility of energy crops which allow the commercial exploitation of these soils by establishing biofuel feedstock production systems can offer a solution. Additionally, plant cultivation offers opportunities for site remediation.Field experiments have been performed on heavy metal contaminated arable soil located in southern Poland, in the vicinity of a former smelting factory. Although heavy metal concentration exceeded standards, the area has been used for agricultural purposes. Experiments involved testing Switchgrass (Panicum virgatum) cultivated with standard NPK fertilizers and commercially available microbial inoculum. Biomass water, macronutrients (N, P, K, Mg, Ca) and heavy metal (Cd, Pb, Zn) content in aboveground plant organs were assessed at the end of two growing seasons.Switchgrass biomass water content was higher after the second year for nearly 40%. Additionally, after the first as well as the second year fertilizers increased it. Magnesium content, essential in chlorophyll biosynthesis, was higher in the first year and additionally more evident in fertilized variants after every year. Heavy metals accumulation in aboveground organs was lower after the second year compare with the first year. Similar trend was observed for Ca and N plant accumulation. However P and K accumulations were higher after the second year of experiment.In conclusion, due to acclimatization, switchgrass reduce heavy metal uptake, what could result in increase of two biogenic elements (P, K) essential in plant growth.

“…The data reveals that the accumulation of Cd was mainly seen in all parts of the plant and was progressive when increasing amount of exogenous Cd was applied. Different application levels of Cd (up to 800 µM) were used in researches related with Cd toxicity (Yang et al, 2004;Nedjimi and Daoud, 2009;Goncalves et al, 2009;Meng et al, 2009). By previous studies performed by Wagner (1993), and Sanita di Toppi and Gabrielli (1999), Cd concentrations (in mM) were found to be between 0.04-0.32 in unpolluted and 0.32-1 in moderate level of polluted soils, respectively.…”

In order to make assessments in understanding of physiological and genotoxic effects of imposing cadmium (Cd) on photosynthetic pigment contents along with the changes occurring in genetic material of Kalanchoe plants were used in relation to various Cd-treatments. Young plantlets were originated from a single host plant as clones, and developed in vitro. Developed clones were grown in standard pots with daily watering of Hoagland solution (20 ml) containing different concentrations of cadmium chloride for two months. Cd concentrations of the collected samples were measured by employing ICP-OES and RAPD-PCR technique was applied for detecting the genotoxic effects of Cd. After two month of experimental period, the comparisons between unexposed and exposed Kalanchoe clone groups revealed reductions in photosynthetic pigment contents, especially at the highest level of Cd exposure and a genomic instability when application of Cd concentration increases. RAPD-PCR analyses demonstrated the distinguishable banding pattern in number and band intensities between Cd-treated and control groups. In addition, progressive Cd accumulations in leaves, stems and roots of plant samples were observed when the application of exposure level increased.

“…In these so-called hydroponic systems, different crops are being successfully produced on a commercial scale, under highly homogeneous and controlled cultivation conditions. There are several studies with heavy metals, using hydroponic systems for the evaluation of responses to, for example, metal accumulation in the plant tissues (Pereira et al 2002, Fourcaud et al 2008, Zhang et al 2009), responses to enzymes linked to the antioxidant system (Ferreira et al 2002, Gonçalves et al 2009, López-Millán et al 2009, interactions with macronutrients (Gonçalves et al 2009), and of toxic effects on plants (Benavides et al 2005, López-Millán et al 2009). Furthermore, cultivation in a hydroponic system has the advantage of generating less waste, since the contaminated nutrient solution can be evaporated, reducing the final metal residue to few milligrams.…”
