“…The exudation of carboxylic acids and protons, at least under conditions of P deficiency, is lower in wheat than in lupin (Neumann and Römheld 1999;Wang et al 2008). Organic anion exudation, rhizosphere acidification, and root reducing capacity are crucial in stimulating the uptake of metals by plants (Husted et al 2005;Hoffland et al 2006). The metal acquisition strategies can explain, at least in part, the differences observed in the effect of T34 on the uptake of Cu, Mn, and Zn between wheat and lupin grown in ferrihydrite-enriched calcareous media.…”

Effect of Trichoderma asperellum strain T34 on iron, copper, manganese, and zinc uptake by wheat grown on a calcareous medium

Rhizosphere microbes may enhance nutrient uptake by plants. Here we studied the effect of Trichoderma asperellum inoculation on the uptake of Fe, Cu, Mn, and Zn by wheat (Triticum aestivum L) grown in a calcareous medium. To this end, an experiment involving two factors, namely Fe enrichment (ferrihydrite enrichment and non-enrichment of the growing medium), and inoculation/non-inoculation with Trichoderma asperellum strain T34, was performed twice under the same conditions. The increase in Fe availability as a result of ferrihydrite enrichment did not enhance plant dry matter production. The effect of T34 on the concentration of Fe, Cu, Mn and Zn, and the total amount of Cu, Mn, and Zn in the aerial parts differed depending on the degree of ferrihydrite enrichment. Inoculation with T34 increased Fe concentration in Fe-deficient media, thus revealing a positive effect of this microorganism on Fe nutrition in wheat. However, T34 significantly decreased the concentration and total amount of Cu, Mn, and Zn in the aerial parts, but only in ferrihydrite-enriched medium. This adverse effect of T34 on Cu, Mn, and Zn uptake by wheat plants may have been related to conditions of restricted availability where potential competition for nutrients between microorganisms and plants can be more marked.

Can silicon partially alleviate micronutrient deficiency in plants? a review

Silicon protects plants against various biotic and abiotic stresses, including metal toxicity. Under a high metal concentration, Si can externally decrease metal availability to the plant by its precipitation in the growth media, and Si also affects the metal distribution inside the plant, diminishing the damage. Could Si also protect plants against metal deficiency stress? Recently, the physiological role of Si in relation to micronutrients deficiency symptoms has been assessed in several plant species in hydroponics. In cucumber, Si supply mitigated the symptoms of Fe deficiency, but this effect was not clear under Zn-or Mndeficiency conditions. The main factor controlling this beneficial effect seems to be the Si contribution to the formation of metal deposits in the root and/or leaves apoplast and its role in their following remobilization when required. The enhancement of the content of long-distance transport molecules (such as citrate) due to Si addition should also contribute to the metal transport from root to shoot, which will diminish deficiency symptoms.

“…Danish soils, especially those formed on old marine sediments, are frequently prone to Mn deficiency, in particular affecting winter forms of barley and wheat. Recent years have seen an increase in Mn deficiency problems on formerly problem free soils, possibly as a result of cultivation practices such as liming or slurry application, with subsequent increases in soil pH and soil P (Husted et al, 2004b). Under such conditions, plant available Mn declines (White and Zasoski, 1999), and now Mn deficiency has become the foremost plant nutritional problem in Denmark.…”

Eight different winter barley genotypes were grown in a plot experiment in northern Denmark, on soil where Mn deficiency had been previously demonstrated, to assess field performance and grain yield under two treatments: with foliar Mn fertilisation and without foliar Mn fertilisation. A high Mn efficiency was demonstrated for two of the genotypes and a low Mn efficiency was observed for one of the genotypes in three consecutive years; highly variable results were obtained for other genotypes. Mn efficiency based on grain yields could not be related to whole shoot Mn concentration, biomass or Mn uptake at various vegetative growth stages. Chlorophyll a fluorescence analysis was able to differentiate between the two Mn treatments up to 7 weeks after the last Mn application, whereas Mn concentrations, shoot biomass and Mn accumulation could not. It was not possible to fully alleviate Mn deficiency by repeated foliar spraying on the control plots. Given the growing conditions at the trial site and the low Mn in plant tissue, it is possible that Mn deficiency was extreme enough that Mn efficiency mechanisms broke down.Abbreviations: Mn -manganese; GS -growth stage; F o -minimum fluorescence; F m -maximum fluorescence; F v -variable fluorescence.
