Peroxidase isoenzymes in germinating barley seeds and in seminal roots

Abstract

Roots and germinating seeds of summer barley of the cv. Alsa, Antałek, Cebeco 7161, Lubuski, Skrzeszowicki and Union were found to differ in the number of peroxidase isoenzymes. In the germinating seeds from 5 to 8 isoenzymes were found whereas in the two-week-old roots – from 10 to 14 isoenzymes. Four isoenzymes in germinating seeds and eight isoenzymes in seminal roots appeared in all the cultivars tested. The cultivars differed also in the relative activity of the isoenzymes in the tested organs.
