“…Concentration of Mn tended to be lower at increased efficiency of Fe sources in decreasing the incidence of Fe chlorosis as measured by the increment in DM and total Fe in shoots (Table 1). This can be ascribed to an antagonistic effect of Fe supply on Mn nutrition of plants (Chatterjee et al, 2006;Caballero et al, 2009), and agrees with previous evidences that Fe supplied as Fe-chelate decreased the Mn concentration in plant shoots to a greater extent than that for inorganic Fe sources under conditions of restricted Fe availability in the growing media (Heitholt et al, 2003;Caballero et al, 2009). Low Zn concentrations in all the treatments can be ascribed to a diminished absorption induced by the growing medium.…”

La aplicación de sales de hierro con materia orgánica de diferentes fuentes ha demostrado ser efectiva en la prevención de la clorosis férrica. El principal objetivo de este trabajo fue estudiar la efectividad de distintas fuentes de Fe formadas a partir de la mezcla de sustancias húmicas o compost con vivianita, en la prevención de este desorden nutricional en fresa (Fragaria x ananassa cv Camarosa). Para ello, se dispuso en un invernadero un experimento diseñado en bloques al azar, con 4 repeticiones (3 plantas por repetición) y un solo factor (la fuente de Fe), usando un medio calcáreo como soporte para las plantas. Las fuentes de Fe estudiadas fueron: (i) testigo sin Fe, (ii) testigo con una fuente efectiva de Fe en medios calcáreos (EDDHA-Fe, 0.1g kg-1), (iii) vivianita (1 g kg-1 medio, dosis recomendada), (iv) vivianita (1 g kg-1) + sustancias húmicas (–SH– 0.06 g kg-1), (v) vivianita (0.5 g kg-1) + SH (0.06 g kg-1) y (vi) una mezcla de corcho compostado y vivianita en una relación 6:1 en peso (CORVIV) aplicada a una dosis de 6 g kg-1 medio. Todas las fuentes de Fe fueron efectivas incrementando las medidas de clorofila SPAD cuando se compararon con el testigo sin Fe. Los tratamientos basados en vivianita no produjeron diferencias significativas respecto a aquellos obtenidos con EDDHA-Fe. Sin embargo, solo el CORVIV no mostró diferencias significativas con respecto al quelato de Fe en cuanto a la producción de materia seca (MS), el área foliar y el contenido en Fe total presente en la parte aérea. Las sustancias húmicas y la vivianita aplicadas en la dosis recomendada (1 g kg–1) incrementaron la producción de MS en las plantas con respecto a la vivianita sin sustancias húmicas. Además la vivianita aplicada sin mezclar con materia orgánica resultó comportarse de forma similar a la dosis inferior de vivianita (0.5 g kg–1) aplicada junto con sustancias húmicas. Se podría concluir que las fuentes de materia orgánica estudiadas incrementaron la eficiencia de la vivianita en la prevención de la clorosis en fresa, especialmente cuando la vivianita se enriqueció con compost de corcho, siendo tan efectiva como el EDDHA-Fe.

“…The high level of some metals like Fe and Cu may inhibit the chlorophyll content (Baszynski et al 1980;Gallego et al 1996;Chatterjee et al 2006), but also nutrient deprivation like N deficiency may induce reduction in chlorophylls (Deckmyn and Impens 1997) as it was the case for distilled water plants (Fig. 3) in which chlorophylls and carotenoids concentration was decreased.…”

“…Redox active metals like Fe may produce potentially toxic reactive oxygen species (ROS) via Fenton-type reactions that activate different antioxidant systems (POD, superoxide dismutases, glutathione, etc) (Schützendübel and Polle 2002). In other species, the increase of Fe in leaf led to an increase in POD activity as in potato (Chatterjee et al 2006). But higher levels of POD activity were also detected in leaves or roots of plants under Cu, Mn and Zn toxicity (Leidi et al 1986;Mazhoudi et al 1997;Prasad et al 1999;Rao and Sresty 2000;Teisseire and Guy 2000).…”

Stress responses of Erica andevalensis Cabezudo & Rivera plants induced by polluted water from Tinto River (SW Spain)

The effects of Tinto River water on Erica andevalensis growth, biochemical indicators and elemental concentration and distribution were investigated under laboratory conditions. High levels of toxic elements such as B, Fe and S and acidic pH characterized the river water. Plant analysis revealed that the concentration of Al, B, S and Fe increased in all plant organs reaching in some cases values in the toxicity range. Plants transferred into river water stopped growing and stress was manifested by plant water loss, increase in peroxidase activity and decrease of chlorophyll a concentration. Significant decreases of free amino acid concentration were found in shoots and roots of plants grown in diluted river water. The results indicated that Tinto River water acidity and its excess in soluble elements produced altogether severe alterations in roots affecting plant water and nutrient uptake and leading to the massive entry of some metals (e.g. Fe, Al) with toxic effects. Scanning-electron microscopy (cryoSEM and ESEM) observations showed that E. andevalensis had not exclusion mechanisms of Cu, Fe and S therefore it was not able to reduce translocation to aerial parts.

“…Plantas submetidas a concentrações elevadas de Fe absorvem e acumulam grandes quantidades deste elemento em seus tecidos, exibindo sintomas típicos de toxicidade, como amarelecimento e, ou bronzeamento das folhas e escurecimento das raízes (CHATTERJEE; GOPAL; DUBE, 2006;SIQUEIRA-SILVA et al, 2012). Sob esta condição, o Fe induz a formação de espécies reativas de oxigênio (JUCOSKI et al, 2013;SILVEIRA et al, 2007), causando severas reduções no crescimento e na produtividade das plantas.…”

Excesso de ferro sobre o crescimento e a composição mineral emEugenia uniflora L. 1Excess iron on growth and mineral composition in Eugenia uniflora L. ABSTRACT -Iron, although an essential micronutrient, when present in excess can cause a reduction in the growth, and hence the productivity, of plants. The aim of this study was to evaluate the absorption, accumulation and distribution of Fe, and its consequences on growth and mineral composition in young plants of Eugenia uniflora L.. The plants were exposed to different concentrations of Fe, 0.045 (control), 1.0 and 2.0 mM, applied in the form of Fe-EDTA in Hoagland's pH 5.0 nutrient solution for 15, 30 and 45 days, when the number of leaves, shoot height, primary root length, dry mass of the roots, stems and leaves, and the levels of chlorophyll, total carotenoids and minerals were evaluated. Plants exposed to the treatments with 1.0 and 2.0 mM Fe showed an increase in levels of the element in the leaves, stem and roots, compared to the control plants, especially after 45 days of exposure. Under that condition, the plants exhibited typical symptoms of Fe toxicity, characterised by leaf bronzing, darkening of the roots, a reduction in the number of leaves, shoot height, length of the main root, dry matter production and the levels of chloroplast pigments. Excess Fe modified biomass partitioning and caused a reduction in the levels of P, Zn, Cu and Mn, especially in the roots. In addition to the direct effect of excess Fe, the resulting nutritional disorder may be associated with restrictive effects on initial vegetative growth in plants of Eugenia uniflora L..
