EVALUATION OF SELECTED PHYSICOCHEMICAL PARAMETERS OF TWENTY-ONE DETERMINATE VARIETD3S OF TOMATO FRUITS (LYCOPERSICON ESCULENTUM Mill.) GROWN IN POLAND

摘要

The aim of the research was to assess the quality of 21 soil-grown determinate tomato varieties. All of them are recommended for crop production in Polish climate conditions. The colour of fruits and the contents of dry mass, extract, total sugars, vitamin C and carotenoids were analysed. It is not feasible to select one single variety with high levels of all the studied parameters. The varieties with the highest content of total carotenoids (Ricoco and Progress) are characterized by the low contentof vitamin C. Malinowy Kujawski variety is characterised by the high content of dry mass and the highest content of total extract and sugars. However, it has the lowest value of o* parameter and low content of carotenoids. Due to small size of fruits, high contents of dry matter, total extract, sugars and total carotenoids Progress variety can be recommended both for the fresh market and processing.
