. "Naphthoquinones belong to group of allelopathic metabolites widespread in nature. They embody broad-range of biological actions from phytotoxic to fungicidal. The main aim of this work was to suggest a technique suitable to determine lawsone, juglone and/or plumbagin in biological samples and to study of their influence on BY-2 tobacco cells. The BY-2 tobacco cells were cultivated in the presence of the naphthoquinones of interest (500 ug.l-1) for 24 h and then the morphological changes were observed. We found out that naphthoquinones triggered the programmed cell death at BY-2 cells."@en . "12"^^ . . "RIV/62156489:43210/06:00103413!RIV07-GA0-43210___" . "11" . . "Adam, Vojt\u011Bch" . . .
