EDTA either binds with Cr to form Cr-EDTA complex or increases the concentrations of soluble and exchangeable form of Cr by lowering soil pH and, thus, increases the bioavailability and facilitates the transport [24]. In the present study, the BAF and TF both increased with increasing Cr(VI) concentrations in soil and the EDTA application resulted in further enhancement of their values.…”

“…Whereas, a high concentration of Cr(VI) hinders water transport, reduces transpiration, affects root uptake of mineral elements, and interferes with enzymatic reactions in plants, which results in plant dwarfing, leaf yellowing and shedding, and biomass reduction [19,20,21,22,23]. In addition, Bareen and Tahira [24] found that seven different cultivated plant species absorbed more Cr under EDTA application. Although the phytotoxicity and remediation potential under soil Cr(VI) stress has been investigated in many plant species, the Pennisetum species have been given less attention.…”

Hexavalent chromium [Cr(VI)] contamination has become an emergent concern in China. Previous field investigations have found that hybrid Napier grass is widely distributed in Cr(VI) contaminated areas. This study investigated the phytoremediation potential and biochemical response of hybrid Napier grass (Pennisetum americanus L. × Pennisetum purpureum Schumach) grown in soil contaminated with Cr(VI) (0, 20, 40, and 60 mg kg−1) with and without Ethylene diamine tetra acetic acid (EDTA) (4 mM) application. The results indicated that root length, shoot height, dry weight, leaf area, chlorophyll, and photosystem II (PSII) parameters viz.; apparent electron transport rate (ETR), effective quantum yield of PSII (ΦPSⅡ), maximal PSII photochemical efficiency (Fv/Fm), potential activity of PSII (Fv/Fo), photochemical quenching (qP), and non-photochemical quenching (qN) decreased with the increasing Cr(VI) concentration. EDTA application further aggravated reduction of dry biomass and photosystem II. The concentration and the accumulation of Cr in shoot and root, and both the bioaccumulation factor (BAF) and transfer factor (TF) increased with increasing Cr(VI) concentrations and further enhanced with EDTA application. Though the Cr(VI) and Ethylene diamine tetra acetic acid (EDTA) stress reduced tolerance, but, even at highest Cr(VI) concentration, plant could exhibited strong resistance, as evidenced by increase in superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) activities. Hybrid Napier grass, due to its BAF > 1 and a TF < 1, would be applicable for Cr phytostabilization. Moreover, limiting metal transport to aerial parts of plant would prevent animal’s ingestion, restrict soil mobility, and consequently reduce transmission across the food chain.

“…Many studies have been reported with the use of chelating agents such as CDTA, HEIDA, HEDTA, DTPA, EGTA, and EDDHA (Marques et al 2009;Firdaus-e-Bareen and Tahira 2010). Other biodegradable chelating agents-namely, malic, citric and nitriloacetic acids have also been proposed for enhanced phytoextraction (Quartacci et al 2006).…”

EDTA-enhanced lead phytoremediation in sunflower (Helianthus annuus L.) hydroponic culture

The aim of the present study was to investigate the capability of Sunflower (Helianthus annuus L.) to tolerate and accumulate high amount of lead (Pb) and propose it for soil phytoremediation. To this regard, plants were grown in hydroponics and treated with different Pb concentrations (10 to 160 μM) and a fixed concentration (500 μM) EDTA (ethylene diamine tetra acetic acid) for 14 and 28 days (d). Effects on total biomass production, photosynthetic pigments and protein contents as well as the quantities of non protein thiols (NP-SH), glutathione (GSH), phytochelatins (PCs) and activity of glutathione reductase (GR) were estimated. Results revealed that roots (575 μg g −1 DW) and shoots (135 μg g −1 DW) accumulated Pb after 28 d of exposure, however, addition of EDTA enhanced the Pb accumulation in roots (645 μg g −1 DW) and shoots (255 μg g −1 DW ). Exposure of Pb (28 d) registered a significant (P<0.05) reduction in growth parameters and induction of phytochelatins (P<0.05; r=0.26) plus some of the important antioxidants (P<0.05; r= 0.42), which were positively correlated to metal accumulation. Sunflower exposed at 40 μM of Pb for 28 d synthesized higher quantity of PC 2 (18.5 fold) and PC 3 (10.5 fold), as compared to control. However, the results showed that addition of EDTA resulted in low toxicity compared to Pb alone. These data support the capability of H. annuus L. to accumulate and tolerate significant quantity of Pb and its utility for phytoremediation. This is because of the plant has the capacity to combat metal induced oxidative stress via significant synthesis of NP-SH, GSH and high activity of GR, as it would provide sufficient GSH not only for PCs synthesis but also for antioxidant function.

Salt stress tolerance mechanisms and potential applications of legumes for sustainable reclamation of salt‐degraded soils

et al. 2018

View full text Add to dashboard Cite

Soil salinity is considered one of the most detrimental environmental problems affecting the productivity of many agricultural crops, with negative effects on seed germination, plant vigour, and crop yields. To mitigate these negative effects, it is necessary to restrategize and identify viable options that are environmentally and economically applicable for sustainable agriculture. This review summarizes and evaluates soil reclamation strategies that have been employed and those that could potentially be used, concentrating on the use of legume crops. Apart from the fact that legumes have many nutritional benefits as foods, they are also an attractive option to refertilize degraded and nitrogen‐deficient soils. Thus, the potential use of grain, grass, shrubby, and tree legumes to restore degraded soils requires evaluation. In this paper, we discuss and evaluate why legumes should be considered and used for the reclamation of degraded soils, with a particular focus on salt‐degraded soils. Globally relevant case‐studies that demonstrate how legumes could be used to reclaim salt‐degraded soils are highlighted.
