Nickel bioaccumulation by the chosen plant species

Abstract

The investigations aimed at the evaluation of nickel bioaccumulation ability of plants from various families (Poaceae-maize, Fabaceae-field bean and Asteraceae-lettuce). The research was conducted under hydroponic conditions. The experimental design comprised ten objects differing with nickel concentrations in the solution (ranging from 0.0 to 10.0 mg Ni dm -3 of the nutrient solution). The parameters, assumed as the basis on which nickel bioretention by selected plant species was determined were: the yield, nickel content in various plant parts, uptake and utilization of this element by the plant, tolerance index (TI) and translocation factor (TF), the metal concentrations in the aboveground parts index (CI) and bioacummulation factor (BAF). On the basis of the obtained results it was found that, due to low tolerance of nickel, maize could be used as the indicator plant for the environment quality assessment.

Relationship between assimilable-nutrient content and physicochemical properties of topsoil

“…Not only soil reaction, humus content and macroelement availability in soils, but also optimum levels of soil micronutrients are of crucial importance to obtaining highquality crop yields (Antonkiewicz, 2010;Antonkiewicz et al, 2016;Rutkowska et al, 2014b;Su and Yang, 2008). Micronutrient contents in topsoil, divided into specific agronomic categories, are presented in Table 4.…”

“…In order to properly identify plant fertilisation needs, the current supply of certain macroelements to the fertilised soils has to be known. These include such elements as phosphorus (Berg and Joern, 2006;Bünemann et al, 2011;Fernandes et al, 2000;Mc Dowell and Sharpley, 2003), potassium (Brennan and Bell, 2013;Fotyma, 2007;Moody and Bell, 2006), magnesium (Tkaczyk et al, 2016;Tyler and Olsson, 2001) and sulphate-sulphur (Gąsior and Alvarez, 2012;Szulc et al, 2014), and microelements such as boron (Majidi et al, 2010;Shaaban, 2010;Szulc and Rutkowska, 2013), copper Su and Yang, 2008), iron (Mcgrath and Zhao, 2006), manganese (Antonkiewicz et al, 2016) and zinc (Barczak et al, 2009;Domańska, 2009;Rutkowska et al, 2014a). This knowledge should be complemented by the equally important data on other physicochemical properties of the fertilised soils, such as pH KCl or humus content (Aponte et al, 2010;Lipiński and Bednarek, 1998).…”

Chemical Innovation in Plant Nutrition in a Historical Continuum from Ancient Greece and Rome until Modern Times

“…It is more and more often the case that such fertilization systems are precisely controlled with the use of computer techniques. Great hope is also placed on the development of plant growing in hydroponic, water, aeroponic systems without soil participation, or using artificial soil, mineral wool substrate and substrate made of other materials [28][29][30][31]. These systems also require plant nutrition with fertilizers with composition specially designed for specific requirements of species and even varieties of plants.…”

Phytoremediation potential of Phalaris arundinacea, Salix viminalis and Zea mays for nickel-contaminated soils

“…So far no studies have been done on the potential for reed canary grass in areas contaminated with Ni, despite the fact that this plant produces a lot of biomass and is often used as a source of energy. On the other hand, research on the potential of Ni phytoremediation of other species, mainly willow and maize, was mostly carried out in pots, or more often, in hydroponics, which does not reflect field conditions in which these plants actually grow (Antonkiewicz et al 2016;Drzewiecka et al 2012;Kopittke et al 2010;Seregin et al 2003). The only available study on willow and maize conducted under field conditions was on the soils contaminated with several metals jointly, which did not allow to draw conclusions about the Ni exclusively (Algreen et al 2014;Kacalkova et al 2014;Mleczek et al 2009).…”
