Silicon (Si) effects on mineral nutrient status in plants are not well investigated. It is known that Si has a beneficial effect under stressed conditions. The aim was to make state of the art investigation influence: (1) availability four different soil types, namely clayish, sandy, alum shale and submerged soil; (2) accumulation various nutrients maize, lettuce, pea, carrot wheat growing hydroponics. Soil treated with K₂SiO₃ corresponding 80 1000 kg ha-1 medium 100, 500, 5000 μM Si. In...

Silicon (Si) has been shown to ameliorate the negative influence of cadmium (Cd) on plant growth and development. However, mechanism this phenomenon is not fully understood. Here we describe effect Si growth, uptake subcellular distribution Cd in maize plants relation development root tissues.

ABSTRACT Willow is shown to be able accumulate high levels of heavy metal ions such as cadmium and zinc. The properties willow used in phytoextraction therefore have been studied. In this article, results from different studies on metals demonstrate the capacity possibility using Salix phytoextraction. KEY WORDS: cadmium, copperheavy metalsphytoremediation zinc

Various clones of Salix spp. have contrasting characteristics accumulation, translocation to shoots and sensitivity cadmium (Cd). The aim was investigate the structure adventitious roots find out if differences between groups in root anatomy accounted for relation Cd. Stem cuttings eight with different combinations high or low Cd Cd, were cultivated 3 weeks hydroponics containing 100 µ M Ca(NO ) 2 . No added this experiment. Equal‐sized selected hand‐sectioning fluorescence staining detect...

ABSTRACT In Southeast Asia the aquatic macrophyte water spinach ( Ipomoea aquatica Forsk.) is a popular vegetable that cultivated in freshwater courses. These often serve as recipients for domestic and other sorts of wastewater contain variety pollutants, such heavy metals. addition, fertilizers are frequently used where commercially food market. To estimate importance ambient nutrient concentrations accumulation mercury (Hg), cadmium (Cd), lead (Pb) spinach, plants were exposed to solutions...

The intent of this study was to investigate whether high levels cadmium (Cd) in the grains Cd‐accumulating cultivars is caused by a Cd uptake roots, translocation from roots shoot, or redistribution between shoot and grains. High low accumulators, with respect grain accumulation Cd, spring winter bread wheat ( Triticum aestivum L.) durum T. Desf.) were selected field studies. grown nutrient solution containing 0.5 m M climate chamber for (i) 19 d (ii) until maturity. concentration flag...

ABSTRACT This study was performed to investigate mercury (Hg) tolerance, accumulation, and translocation within the genus Salix for potential use of this plant remediate Hg‐contaminated sites. Six clones willow ( spp.) were tested on tolerance Hg by treating plants grown in solution culture with 0 15 μ M HgCl 2 Results showed that had a large variation its sensitivity Hg. However, accumulation shoots similar eight as shown cold vapor atomic absorption spectrometry analysis when treated 0.5...

Remediation of stormwater polluted with heavy metals should be possible in percolation systems, ponds, or wetlands. The aim this work was to find plant species for such systems that are efficient the uptake Zn, Cu, Cd, and Pb. Plants were collected from wetland areas analyzed metal concentrations. Results showed submersed free-floating plants had capacity take up high levels Pb into their shoots. With roots having a concentration factor above 1, terrestrial show stabilization Cd Zn emergent...

Sugar‐beet plants ( Beta vulgaris L. cv. Monohill) were cultivated for 4 weeks in a complete nutrient solution. Indirect effects of cadmium studied by adding 5, 10 or 20 μ M CdCl 2 to the culture medium while direct determined 1, 20, 50 000 assay media. The photosynthetic properties characterized measurement CO fixation intact plants, fluorescence emission leaves and isolated chloroplasts, photosystem (PS) I PSII mediated electron transport ‐dependent O evolution protoplasts. When directly...

We have found that aquatic plants can reduce the content of perfluorinated alkyl substances (PFAS) within a short period time. The aim this study was to determine variation in uptake PFAS from contaminated water by various wetland plant species, investigate effect biomass on removal, and whether laccases peroxidases are involved removal degradation PFAS. Seventeen emergent one submerged species were screened for highly lake water. screening showed Eriophorum angustifolium, Carex rostrata,...

The aquatic plant water spinach (Ipomoea aquatica), either wild or cultivated, is found throughout Southeast Asia and a widely consumed vegetable in the region. Many of waters where I. aquatica grows serve as recipients for domestic other types wastewater. Because these contain not only nutrients, but often also wide variety pollutants such heavy metals from various human activities, many people risk intoxication. To estimate accumulation lead (Pb), cadmium (Cd), total mercury (total Hg),...
