| Summary: | The aim of this study was to test the pea plant as sentinel specie for the
heavy metal molybdenum. Evaluation of soil quality after the molybdenum uptake by
pea revealed the following results: Pea plant is a bioindicator that concentrates
molybdenum with fast reaction to increasing concentrations in soil. Molybdenum
had a positive effect concerning the plant growth (throughout all experimental
process, pea plants treated with highest concentrated metal solution reached the
largest dimensions). Accumulated molybdenum was directly proportional to
increasing concentration of the applied solution to roots, stem, leaves and flowers of
the experimental plants; however it resided in flowerpot soil too .In the leguminous
roots where the nitroreductase and nitrogenese activity is increased, molybdenum
content was much higher compared to the aerial parts of the plant. All the way
through molybdenum accumulation in the experimental plants up to high
concentrations, other chemical elements revealed lower concentration although
within the normal limits, with the exception of phosphorus. These plants were found
to assimilate high molybdenum quantities without any detrimental consequences for
them since molybdenum accumulation occurred in vacuoles in innocuous chemical
forms. |
