Effects of fusaproliferin (FUS) on membrane potential (EM), electrolyte leakage, enzymes activity and respiration of roots, were studied in two maize cultivars (Zea mays L.), differing in their susceptibility to this toxin. In short-term experiments (≤ 6 h), EM has been rapidly and significantly depolarized by FUS. The rapidity of EM depolarization in tolerant cv. Lucia was more expressive in comparison...
The Echinacea species are native to the Atlantic drainage area of the United States of America and Canada. They have been introduced as cultivated medicinal plants in Europe. Echinacea purpurea, E. angustifolia and E. pallida are the species most often used medicinally due to their immune-stimulating properties. This review is focused on morphological and anatomical characteristics of E. purpurea, E. angustifolia, E. pallida...
In this study, the effects of Cd on root growth, respiration, and transmembrane electric potential (Em) of the outer cortical cells in maize roots treated with various Cd concentrations (from 1 µM to 1 mM) for several hours to one week were studied. The Em values of root cells ranged between −120 and −140 mV and after addition of Cd they were depolarized immediately. The depolarization was concentration-dependent...
