ORGANOSPECIFIC REACTIONS OF YELLOW LUPIN SEEDLINGS TO LEAD

摘要

Changes caused by lead, supplied in the form of Pb(NO_3)_2, in roots and hyocotyls of 4 day old yellow lupin (Lupinus luteus L.cv. ventus) seedlings have been analyzed using a transmission electron microscope and polyacrylamide gel electro- phoresis (PAGE). The cells of all examined parts of the roots growing in the presence of Pb~2+ contained many lead deposits (mainly in the cell walls and vacuoles) and the increased amount of polypeptides of molecular weight close to 16 kDa have been observed. Similar changes were detected in the area of hypocotyl adjoining the root.
