“…Hence, our results of Cd toxicity and reduction in growth rate observed in the castor accessions compared to the control may also be due to the high Cd concentration which restricted the intake of essential nutrients in the growth medium thereby disrupting the plant metabolism. These findings are in consonance with previous studies reported in kenaf (Li et al 2013), maize (Xu et al 2014), castor (Hazama et al 2015), sugarcane (Zeng et al 2017), and switchgrass (Guo et al 2019). This present study confirms that high Cd concentration causes cytotoxicity and reduction in plant growth.…”

The present study was conducted to assess the effect of toxicity of cadmium (Cd) on growth, tolerance index (TI), antioxidant activities, and malondialdehyde (MDA) content in two contrasting wild castor accessions (16-024 and S2-4) via hydroponic experiment (0 and 100 mg/L Cd). The results showed that Cd significantly reduced the growth rate, seedling height, root length, and shoot length of the castor accessions compared to the control, with the Cd effect being more severe in S2-4 than in 16-024. In addition, biomass response including the root and shoot fresh weight and root dry weight decreased in both accessions compared to the control. Compared to the control group, the shoot dry weight of accession S2-4 declined by 21.7%, whereas there was no change in 16-024, suggesting a level of tolerance in 16-024. Analysis of TI on all the growth parameters and biomass content revealed that accession 16-024 was highly tolerant to Cd stress than S2-4. The results further revealed that the expression of the antioxidant enzymes, viz., superoxide dismutase (SOD), catalase (CAT), non-enzymatic antioxidant, glutathione, and MDA content, was influenced by genotype. S2-4 exhibited a higher antioxidant activity (SOD, CAT) and lipid peroxidation activity than 16-024, indicative of oxidative damage from Cd stress.

“…Therefore in this study, two contrasting wild castor accessions were used to investigate the growth, biomass production, TI, antioxidant system, and lipid peroxidation in castor under Cd stress for 5 days. The results showed a wide variation between the accessions with respect to all the parameters investigated ( (Guo et al 2019). This present study con rms that high Cd concentration causes cytotoxicity and reduction in plant growth.…”

The present study was conducted to assess the effect of toxicity of cadmium (Cd) on growth, tolerance index (TI), antioxidant activities, and malondialdehyde (MDA) content in two contrasting wild castor accessions (16–024 and S2-4) via hydroponic experiment (0 and 100 mg/L Cd). The results showed that Cd significantly reduced the growth rate, seedling height, root length, and shoot length of the castor accessions compared to control, with the Cd effect being more severe in S2-4 than in 16–024. In addition, biomass response including the root and shoot fresh weight and root dry weight decreased in both accessions compared to control. Shoot dry weight of 16–024 increased (p > 0.05) by 2.04 % compared to S2-4 which declined by 21.07 %, suggesting a minimal effect of Cd and a level of tolerance in 16–024. Analysis of TI on all the growth parameters and biomass content revealed that accession 16–024 was highly tolerant to Cd stress than S2-4. The results further revealed that the expression of the antioxidant enzymes viz., superoxide dismutase (SOD), catalase (CAT), non-enzymatic antioxidant; glutathione, and MDA content, were influenced by genotype. S2-4 exhibited a higher antioxidant activity (SOD, CAT) and lipid peroxidation activity than 16–024, indicative of oxidative damage from Cd stress.

“…Before carrying out a phytoremediation study, the speciation of metals in soil and water should also be considered to evaluate their bioavailability, mobilization processes of these elements in soil-plant or water-plant systems, and their possible interactions with soil particles (Guo et al, 2019;Pan et al, 2019).…”

FITORREMEDIACIÓN in situ EN MÉXICO: UNA REVISIÓN

En México, la contaminación por elementos potencialmente tóxicos en el suelo y el agua representa importantes problemas ecológicos y de salud. Las plantas capaces de crecer en terrenos antropogénicamente modificados reflejan su capacidad de adaptación a diversas condiciones ambientales. La mayoría de los estudios de fitorremediación se lleva a cabo en condiciones de laboratorio, y sólo unos pocos estudios evalúan la capacidad de fitoextracción in situ. Esta revisión resume la información obtenida de fuentes científicas sobre los estudios de fitorremediación in situ realizados en México. El 85% de los estudios reportados corresponde a sitios contaminados con metales traza por actividades mineras. Se describen plantas con potencial para ser utilizadas como acumuladoras o hyperacumuladoras de elementos potencialmente tóxicos, como Hydrocotyle ranunculoides, Parietaria pensylvanica y Commelina diffusa para Zn; Rorippa nasturtium-aquaticum y Simsia amplexicaulis para Cu; Nicotina glauca, Flaveria angustifolia y Flaveria trinervia para As y Buddleja scordioides para la fitoremediación de suelos contaminados por Pb. Las especies de plantas nativas deben estudiarse para establecer mecanismos de fitoextracción de metales y la interacción agua-suelo-microorganismos para mejorar la eficiencia de la fitorremediación in situ. La información aquí descrita tiene utilidad para planificar la remediación de sitios contaminados por elementos potencialmente tóxicos en México y para diferentes sitios del mundo.
