Abstract

The influence of various locations that is, climatic and soils factors, on the internal quality of the cv. ‘Williams’ fruits was investigated. The application of the HPLC method enabled us to successfully observe the changes in the contents of individual sugars (glucose, fructose, sucrose), alcohol sugar sorbitol and organic acids (citric, malic, fumaric, and shikimic acids). The contents of soluble solids, total sugars, and total organic acids were measured, as well as the sugars/organic acids and glucose/fructose ratios. Various meteorological (precipitation, temperature, sunlight) and soil (macro and micro elements in the soil) parameters had effects on the contents of individual sugars and organic acids in the fruits of the cv. ‘Williams’. The highest contents of individual sugars (glucose, fructose, and sorbitol), total sugars and soluble solids in the fruits were measured in the area of Bistrica ob Sotli. The differences between the locations were statistically significant. The lowest amount of malic acid in the fruits was observed in the area of Bistrica ob Sotli. In the pear fruits grown in the area of Krško the highest contents of citric and shikimic acids were measured. The glucose/fructose ratio of 0.2 was most closely approached in the fruits grown in the areas of Bistrica ob Sotli and Krško.
