The Biology of Botrytis Cinerea Pers. Isolated from

In our experiments we have identified and isolated the pathogen Botrytis cinerea Pers. from geranium plants, we have inoculated it on three types of culture media (PDA, Czapek –agar, MA) and studied its morphological and cultural characteristics. The results obtained consist in differences in the morphology, number and distribution of the sclerotia and the dimensions of the conidia. The isolates taken under study showed a great phenotypic diversity influenced by the host plant and by the culture medium where they was grown
