    SEITA, Institut du Tabac, Bergerac, France
    Peroxidases and their isoenzyme pattern were studied in two groups of young plants: one resistant to P. tabacina and the other susceptible to P. tabacina during the stages of installation and development of the parasite. When plants were cultivated on ...
