ABSTRACT: This study was undertaken to evaluate the influence of growing systems (conventional,
organic and biodynamic performed with two types of manuring) on some nutritional
traits of the tomato breeding line CXD271BIO (Solanum lycopersicum L.).
Experimental fields were in the same geographical area and the cultivations were
performed over five years. The content of macronutrients, minerals (Ca, K, Mg, P,
Na), trace elements (Fe, Zn, Cu, Mn) and phenolic acids (chlorogenic, caffeic, p-coumaric and ferulic acids) was determined. The biodynamic A growing system
showed the highest protein and carbohydrates content compared to the other growing
systems. Data on minerals and trace elements content showed significant differences
(mainly in Ca, Na, Fe and Zn content) between conventional and biodynamic
tomatoes, whereas no major impact of the fertilization among organic and the two
biodynamic growing systems was observed. Appreciable differences in phenolic acids
biosynthesis were observed, with the year of harvest showing a marked effect especially
on chlorogenic, p-cumaric and ferulic acids content. Conversely, the cultivation
system did not show major influence. Principal Components Analysis (PCA),
performed on mineral and phenolic acids content, substantiated the large effect of
the year of harvest, also suggesting an effect of the conventional cultivation system.
