Original abstract

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 metal ions, 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 determine the changes o

V iontů těžkých kovů a jejich sloučenin jsou považovány za jednu z nejvíce toxických látek znečišťujících životní prostředí ze všech částí. Fotografické odvětví, následující elektrochemie a lékařství jsou hlavní zdroje z jednoho z nejvíce toxických těžkých kovů, ionty stříbra (I) iontů. Cílem této práce je prozkoumat slunečnice rostlin na stresové reakce vyvolané různými dávkami ze stříbra (I) iontů (0, 0,1, 0,5 a 1 mm). Pro tento účel jsme zaměstnáni multi-instrumentální přístroj na odhalování a vyšetřování celkového obsahu bílkovin, aktivita ureázy, prostorové rozložení iontů těžkých kovů, a fyziologické a anatomické změny v ošetřených rostlin (slunečnice, kukuřice, rané somatických embryí). Rostliny, kteří byli léčeni přípravkem stříbro (I) iontů za 96 hodin a ve vzorku za 24 hodin po ošetření. Zjistili jsme, že na ošetřených rostlin, zakotvený růst deprese, barvené změny a nedostatek kořene chloupků. Použití autofluorescence z anatomických struktur, jako je lignified buněčných stěn, bylo možné u
