Impact of Cadmium and Copper Excess on Cell Wall Peroxidases in Pea Stems

A. Chaoui and E. El Ferjani    

Abstract: Supply of Cd or Cu to culture medium of 12-day-old seedlings of pea (Pisum sativum L. cv. douce province) was conducted for 4 d. Stems lost growth and increased their cell wall peroxidase activity. Elevation in capacities of NADH-malate dehydrogenase, H2O2-generating NADH oxidase and coniferyl alcohol peroxidase, which successively act in monolignols polymerization, confirmed the stimulation of lignification.
