“…With the exception of compounds 2, 4 and 5, the remaining peaks have been previously identified in C. spinosum by the authors, in plants grown under different saline conditions (Petropoulos et al, 2017) and in different ecotypes of C. spinosum , as well as in leaves of C. intybus (Carazzone, Mascherpa, Gazzani, & Papetti, 2013;Dalar & Konczak, 2014;Heimler, Isolani, Vignolini, & Romani, 2009;Sinkovič et al, 2015).…”

a b s t r a c tIn the present study, the effect of successive harvesting on yield, chemical composition and antioxidant activity of Cichorium spinosum plants was examined. C. spinosum plants were grown from seeds sown in seed trays containing peat and young seedlings were transplanted in 2L pots containing peat and perlite (1:1 v/v). Plants were harvested two or three times during two consecutive growing periods. Total fresh weight and number of leaves were higher for successive harvests in both growing periods comparing to a single harvest. The application of more than two harvests resulted in quality loss during the 1st growing period, while in the 2nd growing period the overall chemical composition, antioxidant properties and phenolic compounds content was higher than the 1st period. In conclusion, cultivation practices such as sowing date and successive harvesting may be useful tools towards the production of high quality end-product with increased bioactive properties without compromising total yield.

“…Only one cauliflower genotype out of 2 and one organic cultivation out of 3 exhibited a higher polyphenols content with respect to conventional management [88]. Flavonoids and polyphenols broccoli content was unaffected by production practices [89], and no differences were found between biodynamic and conventional farming systems in the case of chicory [90]. Oat [91] and rice [92] grains exhibited no differences in the polyphenols content between organic and conventional farming.…”

relevance of scientific studies on this subject. Taking into account the reviews published since 2008, a general overlook on the research topics can emphasize the main current fields in which the research is presently developed. The different subjects which may be inferred are: problems in the analytical assays of polyphenols [1][2][3][4][5], polyphenols composition of fruits and vegetables [6][7][8][9][10], the fate of polyphenols in postharvest technology [11, 12], chemistry and biochemistry [13][14][15][16], polyphenols and food [17][18][19][20][21], polyphenols and health [22][23][24][25][26][27][28]. From this short survey which takes into account only partly the last years, the great number and variety of researches on these plants metabolites can be pointed out. There is a lack of reviews on the relations between polyphenols content, fertilization and agriculture practice, with the exception of a recent review on the possibility of differentiating organic practice by means of secondary plant metabolites in carrots [29], and the review of Stefanelli et al. [18] focused on horticulture quality under minimal nitrogen and water supply.The aim of this review is concerned with the relationships between polyphenols content, fertilization and agricultural practice correlated to soil management. Effect of nitrogen and/or potassium fertilizationAs summed up by Nguyen and Niemeyer [30], the carbon/nitrogen balance (CNB) pathways can be taken into account when studying the effect of nitrogen fertilization on phenolic content. Phenylalanine is the rate-limiting precursor for phenylpropanoid synthesis (e.g., lignin, flavonoids and condensed tannins), and at the same time, it is an essential amino acid for protein synthesis. Plant growth is heavily dependent on protein synthesis for the manufacture of photosynthetic, biosynthetic and regulatory enzymes, as well as for structural protein, and phenolic synthesis Abstract The review deals with polyphenol content of vegetables and fruits under different experimental conditions. The effect of fertilizers, mainly nitrogen containing fertilizers, on qualitative and especially quantitative content of the polyphenols mixture, was reviewed. Soil nitrogen affects both anthocyanins and flavonoids content, and generally, a higher polyphenolic content is observed when less nitrogen fertilizer is added to the soil. Also the effect of different agricultural management (conventional, organic, biodynamic, integrate) is reviewed with respect to polyphenols. In this case, a major effect has pointed out in the case of vegetables, while agricultural practice affects in a minimal way fruits polyphenols content. The effect of different management is, however, hardly pointed out, since many environmental factors are involved and affect polyphenols biosynthetic pathway.

“…PTR-ToF-MS spectra calibration was performed offline, using the peaks of known components, present in the spectra at any time (water isotope, H 3 , m/z = 59.05). All data from each replicate and background signal were normalized, according to Infantino et al [23], by the primary ion signal (cps to ncps).…”

“…In a relatively moderate number of investigations on metabolic compounds in food from biodynamic agriculture as compared to food from conventional or organic management, the attention has been frequently drawn to certain phytochemicals, such as carotenoids, flavonoids, polyphenols, and anthocyanins [3][4][5][6]. Apple fruits (Malus domestica Bork.)…”
