The studies were conducted in 2005-2007 in Lithuanian University of Agriculture. The purpose of research was to establish the influence of mechanical injury of potato tubers on their quality. The experiment showed that during storage some chemical-physiological features had been changing constantly. The potatoes for research were grown under usual conditions in Vokė Branch Station (Lithuanian Institute of Agriculture) in Vilnius region in 2005-2007. For seven months (from September to April) potato tubers were stored in KX-Ю freezing chambers: 5-6°C, relative humidity - 90-95%. The studied samples of potatoes were stored in polythene bags of 120 µ thickness. General and natural weight losses were determined in 2 repetitions, two times: before storing and after seven months of storage. The analyses were carried out using standard methods: dry matter, saccharide content (reducing sugar and saccharose) and store losses of the mass. A suitable laboratorial bruising equipment was used (Fig. 1). The studied potato tubers were bruising from: 10 cm, 15 cm, 20 cm and 100 cm high. Research results showed that after 7 months of storage, all mechanically injured tubers demonstrated the lower content of dry matter as compared to the control sample. Tubers bruised from 100 cm height featured the highest losses of dry matter, whereas the lowest losses were characteristic for tubers bruised from 15 cm height. Tubers injured mechanically from 100 cm height and stored for 7 months demonstrated the greatest mass losses, whereas tubers bruised from 15 cm height featured the lowest mass losses.
