Název v původním jazyce

The response of pepper plants (Capsicum annum, L.) on soil amendment by inorganic and organic compounds of arsenic

Popis výsledku v původním jazyce

The influence of soil contamination by inorganic and organic arsenic compounds on uptake, accumulation, and transformation of arsenic in pepper (Capsicum annum, L.) was investigated in greenhouse pot experiments under controlled conditions. Pepper plantswere cultivated in substrate amended by aqueous solutions of arsenite, arsenate, methylarsonic acid (MA), and dimethylarsinic acid (DMA) applied individually into cultivation substrate at concentrations of 15 mg As per kg of substrate. The plant availability of the arsenicals increased in the order arsenite = arsenate < MA < DMA. The highest arsenic concentrations were found in roots followed by stems, leaves and fruits regardless of arsenic compound applied. In the control samples of pepper fruits, As(III), As(V), and DMA were present (25, 37, and 39% of the water extractable arsenic). In control stems+leaves and roots As(V) was the major compound (63 and 53% in a phosphate buffer extract) followed by As(III) representing 33 and 42%.
