Induction d'un cytochrome du type P450 et de péroxydase durant la survie du tubercule de pomme de terre

Abstract During the ageing of potato tubers, a labile cytochrome of the P 450 type appears, always accompanied by the presence of P 420 -type pigment. This induction of P 450 coincides with an increase in peroxidase activity together with an increase in the amount of cytochrome b 5 .
