This study investigated whether mycorrhizal colonization influences heavy metal uptake by maize. Two experiments were carried out. In the first, 15 commercially available maize varieties cultured on industrial waste substratum and inoculated or not with Glomus intraradices, were treated one week before harvest with EDTA, a chelating agent known to mobilize heavy metals in soil. Estimation of mycorrhizal parameters indicated differences between varieties, but differences between treatments of the same variety generally were not statistically significant. Although EDTA treatment strongly decreased the activity of fungal alkaline phosphatase (indicator of fungal viability), the treatment did not totally eliminate arbuscular mycorrhizal fungi (AMF) from the soil. The appearance of AMF structures within roots was modified in plants cultivated in EDTA-treated soil. Among the heavy metals studied, the highest impact of EDTA treatment on heavy metal uptake in shoots was found in the case of Pb. In most cases, EDTA treatment significantly increased the Pb level in shoots of mycorrhizal plants. Among the samples treated with EDTA, mycorrhizal plants of 6 cultivars showed higher Pb content in shoots than did nonmycorrhizal plants. Significant differences in heavy metal content in plant material were demonstrated between the varieties tested. In the second experiment, one selected cultivar was subjected to high soil Pb concentrations and to EDTA for one week, following cultivation in nonpolluted substratum. In this case, EDTA treatment more strongly influenced Pb uptake by nonmycorrhizal than by mycorrhizal plants. The results indicate the need to carefully screen cultivars as well as microorganism strains to be used in phytoextraction procedures.

Podjęto badania nad akumulacją metali ciężkich Zn, Cd i Pb przez populacje Silene vulgaris z gleby zanieczyszczonej metalami w obecności i przy braku EDTA (kwasu etylenodiaminotetraoctowego). Nasiona pozyskano z trzech stanowisk: (1) najbliższego otoczenia Huty Metali Nieżelaznych „Szopienice” w Katowicach, (2) hałdy pocynkowej Zakładów Metalurgicznych „Silesia” w Katowicach, (3) obszaru pogalmanowego w Dąbrowie Górniczej (Warpie). Gleba była zanieczyszczana Pb, Zn i Cd. Dodawano także EDTA do gleby zanieczyszczonej metalami. Badano akumulację metali ciężkich w liściach, łodygach i korzeniach roślin S. vulgaris. Obliczono wskaźniki translokacji (TF). Dodatek EDTA spowodował wzrost biodostępności metali ciężkich w glebie. W obecności EDTA zanotowano zwiększoną akumulację Zn i Cd w częściach nadziemnych Silene vulgaris oraz Pb u roślin pochodzących z najbliższego otoczenia huty (Szopienice). Najwyższą akumulację Cd i Zn stwierdzono w liściach badanych roślin. U roślin Silene vulgaris, rosnących na glebie z dodatkiem EDTA zanotowano także większą translokację Zn i Cd do części nadziemnych.

A pot experiment was established in 2006 to examine whether induced phytoextraction can remove copper from soils polluted with emissions from copper smelters. Two soils tested in the experiment were sand and loam in texture, and contained 620 and 510 mg⋅kg-1 Cu, respectively. Maize was used as a testing plant. Two chelating agents: EDTA and biodagradable EDDS were introduced into the soils at the rates of 0.2; 0.5 and 1.0 mmol⋅kg-1 to intensify the process of Cu phytoextraction. The results that have been already published indicated that application of both chelators caused increase in Cu uptake by plants in 2006, although the concentrations of Cu in biomass were far below those required for effective phytoextraction. Additionally, both chelators caused intensive leaching of metals from soils. This paper focuses on the carryover effects observed in the subsequent year, 2007, certainly caused by the application of chelators. EDTA, particularly when applied at the highest rate, caused considerable deterioration of plant growth, reduction of plant yields and increased uptake of Cu by plants grown in both soils. The plants showed unquestionable effects of copper phytotoxicity. In the plots where EDDS was applied, a small decrease in yield was observed in the case of plants grown on sandy soil, whereas in plants grown on loamy soil a significant increase in plant yields and decrease in Cu concentrations in shoot biomass occurred compared with the control plots. Cu and Fe concentrations in plant shoots were positively correlated with each other, and the plants with the highest concentrations of Cu also contained the highest concentrations of Fe. Application of the chelating agents, particularly EDTA, in 2006 caused a long-lasting increase of Cu and Fe solubility in soil, and plant uptake of those elements in 2007 correlated positively with soil concentrations of soluble metal forms, extracted with 1 mol⋅dm-3 NH4NO3 and 0.01 mol⋅dm-3 CaCl2.
