Abstract


The aim of the laboratory experiment was the isolation of fungi colonized potato tubers directly (immediately) after harvest and after 5-month storage. 67 potato tubers samples collected in 1998 and 1999 from the areas of province Warmia and Mazury were examined. The occurrence of 36 and 46 species were confirmed on analyzed tubers after harvest and storage, respectively. The most frequent species which occurred on tubers were: Alternaria alternata (9,4%), Colletotrichum cocco- des (12,6%), Rhizoctonia solani (7,4%) and fungi from Fusarium genera (8,7%).This fungi, except Rhizoctonia solani, more often colonized potato tubers afier storage. Among saprofitic fungi most frequent were: Epicoccum (3,4%), Mortierella (3,1%), Mucor (6,0%), Penicillium (17,0%), Rhizopus (7,1%) and Trichoderma (12,9%). More colonies of fungi were obtained from potato tubers analyzed after harvest. Remaining fungi were more frequently isolated after storage.
