Abstract
Lead nitrate at concentration of 150 mg dm−3 inhibits root growth of Lupinus luteus seedlings by bout 20 %, which is accompanied by an increase of K+ leakage from the root cells. Non-denaturing isoelectric focusing in polyacrylamide slab gel has shown that lead stimulates the activity of most lipoxygenase isoenzymes and induces one additional isoenzyme with pI 6.9.
