Abstrakt		The aim of this work was to investigate the effect of potato virus Y NTN on photosynthetic pigments of the potato (Solanum tuberosum L.) cv. Igor grown in soil. Photosynthetic pigments were analysed in the shoots of infected, mock-inoculated, and healthy (PVY NTN-free) control potato plants. The composition and amounts of photosynthetic pigments were studied 24 hours and 5 days after inoculation, before visible symptoms appeared. Pigments were separated by high performance liquid chromatography (HPLC) and identified by their light absorbance characteristics, hypsochromic shifts and retention times. Compared to the control, a decrease of photosynthetic pigments was detected 5 days after inoculation. The changes were more pronounced in infected than in mock-inoculated plants.
