The effect of excess nutrient levels of manganese (Mn, 50 and 100 M) on the growth inhibition
and the appearance of Mn-toxicity symptoms in the leaves was studied in cucumber plants
(Cucumis sativus L. cv. Chinese long). Silicon (Si), when supplied as 1.5 mM silicic acid, clearly
decreased symptoms of Mn-toxicity despite approximately the same total Mn content in the
leaves. In treated plants, Si improves growth and biomass production compared with that of non Si treated plants. Inert deposition of Si in the leaf cell walls of cucumber (a Si-accumulating
species) enhanced cell wall stability. The mechanism of Si protection is proposed to act by Si induced compartmentation of Mn hence increasing Mn2+
-binding sites in the cell wall (e.g. Mn silicate polymers) finally resulting in decreased toxic free Mn within the plant tissue rather than
decrease of Mn uptake. These results suggest that Si nutrition can improve the phytoextraction
potential of plants due to enhanced met...al tolerance in leaf tissues
