Aluminium uptake and translocation in Al hyperaccumulator Rumex obtusifolius is affected by low-molecular-weight organic acids content and soil pH

Popis výsledku v původním jazyce

High Al resistance of Rumex obtusifolius together with its ability to accumulate Al has never been studied in weakly acidic conditions. The potential elucidation of the role of organic acids in plant can explain the Al tolerance mechanism. For the manipulation of Al availability, slightly acidic and alkaline soils were untreated and treated by lime and superphosphate. We determined concentrations of mobile Al in soils and of Al and organic acids in organs of R. obtusifolius. Al availability correlated positively to the extraction of organic acids in soils. Elevated transport of total Al from belowground organs into leaves was recorded in both lime-treated soils and in superphosphate-treated alkaline soil. The highest concentrations of Al and organic acids were recorded in the leaves infusions. In alkaline soil, R. obtusifolius is an Al hyperaccumulator with the highest concentrations of oxalate in leaves, of malate in stems, and of citrate in belowground organs.
