Název v původním jazyce

Affecting of plants by silver ions revealed by electrochemical and spectral techniques

Popis výsledku v původním jazyce

The ions of heavy metals and their compounds are considered as one of the most toxic substances polluting all parts of environment. Photographical industry, following electrochemistry and medicine are the main sources of one of the most toxic heavy metalions, silver(I) ions. The aim of this work is to investigate sunflower plants response on stress induced by various doses of silver(I) ions (0, 0.1, 0.5, and 1 mM). For this purpose we employed multi-instrumental apparatus to detect and investigate total protein content, urease activity, spatial distribution of the heavy metal ions, and physiological and anatomical changes in the treated plants (sunflower, maize, early somatic embryos). The plants were treated with silver(I) ions for 96 h and sampled per 24 hours of the treatment. We found that the treated plants embodied growth depression, coloured changes and lack root hairs. Using of autofluorescence of anatomical structures, such as lignified cell walls, it was possible to determin
