“…3). However, leaf Mn contents was not reduced by Fe addition as reported in other species (Zaharieva 1995). The lower chlorophyll a and b and carotenoids content at high Mn contents might result in photosynthetic inhibition as reported in other species (Li et al 2010;Millaleo et al 2013).…”

The effect of exposure to high Mn concentration was studied in a metallophyte species, Erica andevalensis, using hydroponic cultures with a range of Mn concentrations (0.06, 100, 300, 500 and 700 mg L -1 ). At harvest, biomass production, element uptake, and biochemical indicators of metal stress (leaf pigments, organic acids, amino acids, phenols, and activities of catalase, peroxidase, superoxide dismutase) were determined in leaves and roots. Increasing Mn concentrations led to a decrease in biomass accumulation and tip leaves chlorosis was the only toxicity symptom detected.In a similar way, photosynthetic pigments (chlorophylls a and b, and carotenoids) were affected by high Mn levels. Among organic acids, malate and oxalate contents in roots showed a significant increase at the highest Mn concentration while in leaves, Mn led to an increasing trend in citrate and malate contents. An increase of Mn also induced an increase of superoxide dismutase activity in roots and catalase activity in leaves. As well, significant changes in free amino acids were induced by Mn concentrations higher than 300 mg L -1 , especially in roots. No significant changes in phenolic compounds

“…O' Hara et al (1988) observed the same symptoms in groundnut and explain this by the inhibition of nodule development and therefore N 2 fixation. Fe deprivation also resulted in production of small dark-brown spots on the leaves, particularly in Coco blanc and Striker, which might be symptomatic of Mn toxicity (Zaharieva, 1995).…”

“…The metals compete with iron for ligands both in soils and plants (Mengel et al, 1984;Natt, 1992;. Manganese can substitute for iron in catalase and peroxidase, as shown in citrus (Lavon and Goldschmidt, 1999;Thomas et al, 1998;Zaharieva, 1995). Depending on their concentration, zinc and copper can competitively inhibit access of iron to chelators, thereby decreasing iron uptake from soil (Alva and Chen, 1995;Jolley and Brown, 1994;Schmidt et al, 1997), although the activity of copper in calcareous soils is usually very small because it is complexed by organic substances (Lindsay and Schwab, 1982).…”
