EFFECTS OF DIFFERENT Pb AND Cd CONCENTRATIONS ON BIOAVAILABILITY IN SOME PLANT SPECIES

Abstract

Our research aims to evaluate the effect of bunch load variation per unit area on The aim of this study was to examine the effect of different concentrations of heavy metals Pb and Cd on bioavailability in five plant species: nettle (Urtica dioica L.), spelt/dinkel wheat (Triticum spelta L.), spinach (Spinacea oleracea L.), phacelia (Phacelia tanacetifolia Benth.) and buckwheat (Fagopyrum esculentum Moench). These plant species were sown in containers with substrates contaminated with three different concentrations of Pb and Cd. After removal of the crop,the concentration of these metals was examined in the roots and aboveground organs of the plants. The results showed that with increasing concentration of Pb and Cd in the substrate, their concentration in plants increases, except in spelt where the highest concentration of Pb was recorded in the root of spelt grown on the substrate with the lowest concentration of Pb. The results of phytotranslocation potential showed that buckwheat is a suitable plant species for phytoextraction of both Pb and Cd with all three substrate variants, that is at all tested concentrations of both heavy metals.

The Influence of Fertilisation on the Yield and Antioxidant Capacity of Common and Tartary Buckwheat

“…Yield reduction is associated with crop lodging (Gavrić et al, 2018). Namely, buckwheat is known for its relatively high biomass productivity in different environmental conditions (Leto et al, 2022), contributing to crop lodging (Gavrić et al, 2018). Gavrić and Gadžo (2011) believe that buckwheat is an unpredictable crop in terms of fertilisers, and that poor soils and slowdegrading fertilisers should be preferred in the cultivation of this plant.…”
