The biometrical-experimental examinations of fungi of Peronospora genus, affecting the representatives of Papaver L.

Abstract

The paper presents the results of biometrical-experimental examinations of fungi of Peronospora genus which infect the representatives of Papaver. The investigations seemed to show that on all of three investigated host plants (Papaver argemone, P. rhoeas I P. somniferum) there was only one species of Peronospora.
