To study the effect of cultivation system (conventional and organic) on potato tuber components, 42 parameters (anti-nutritives, micro- and macro-elements and 23 metabolites) were studied in three multi-resistant Hungarian potato varieties for three years in 2007-2009. Discriminant analysis of data proved that all investigated factors (farming technology, genotype and season/year) had significant effect on metabolites. Reversed phase high performance liquid chromatographic (HPLC-DAD, HPLC-MS) and elemental analysis methods have been adapted to quantify the major components, i.e., steroidal alkaloids, nitrite, nitrate, sugars, amino acids and micro-elements, in potato tubers. The absolute amount and changes of tuber components were influenced differentially by the technology, genotype and season in a complex manner. Any examined component, except nitrate content, was found to be significantly higher or lower consistently in relation to the production practice (organic or conventional) during the three years trials. Under the examined circumstances, no consequent positive effect of organic fanning on the total amount of anti-nutritive components, vitamins or micro- and macro-elements of potato tubers could be proven. 展开更多
