Experiments with respect to the changes in plastid number and chlorophyll content (including chlorophyll a, chlorophyll b, and total content of chlorophylls a + b) of the cells of leaf tissues of two Slovak winter wheat cultivars (Hana and Ilona) as infected with a fungal pathogen Tilletia caries (DC.) Tul. were conducted. Reduction in plastid number in the leaf cells of infected wheat cultivars (Hana 53.25 %, Ilona 58.77) was higher as compared to its number in leaf cells of uninfected (Healthy) wheat plants of these cultivars. The chlorophyll a content was also reduced to an higher extent in the infected wheat cultivars (Hana 61.11 %, Ilona 65.97 %). Similar trend was apparent in case of chlorophyll b (Hana 46.63 %, Ilona 59.6 %). The total sum of chlorophyll a + b was also reduced at an higher extent in the infected wheat cultivars (Hana 56.63 %, Ilona 61.73 %) as compared to its healthy counter-part. There were close relations among susceptibility, or on other hand resistance of studied winter wheat cvs. and plastids number, as well as chlorophyll content changes. Further studies and data needs to be generated especially on the reaction of photosynthetic apparatus of these two wheat cultivars after the infection by a fungal pathogen (T. caries). This will enable to undertake possible resistance wheat breeding programmes against smut pathogen and devise more effective, ecologically safe and environmentally friendly plant protection measures
