Vliv naftochinnonů a jejich derivátů na rostlinný organismus
Kopřiva, Vladimír
Naphthoqinones are one of groups of secondary metabolites widespread in nature. The most important higher plant families containing naphthoqinones are Bignoniaceae, Boraginaceae, Droseraceae, Ebenaceae, Juglandaceae, Nepenthaceae and Plumbaginaceae. Naphthoquinones are also products of secondary metabolism of some fungi, lichens and algae. Many investigators have interested in these compounds because of their broadrange biological activities; antibacterial, fungicidal, antiparasitic and insecticidal. In this work, we studied the effects of juglon on hydroponically grown seedlings of L.). Flax plants were exposed to solutions with various concentrations of juglon and the growth and development of pea (Pissum sativum) plants were analyzed. The results showed that juglon significantly affect the morphology and physiology of the pea (Pissum sativum) plants. Moreover, the production of ethylene was increased due to stress conditions.
