“…Our results are in accordance with Koleška et al (2017). The higher K and P fertilization could be potentially responsible for the described trend because they have been reported to positively influence lycopene content in tomato as their supply is increased (Zdravković et al, 2004;Ramírez et al, 2009). The FT-ICR MS analysis of the HA helped provide an understanding of the composition and distribution of major biomolecule classes present.…”

The increasing demands for biostimulants in the agricultural market over the last years have posed the problem of regulating this product category by requiring the industry to make available the information about efficacy and safety, including the explanation of mode of action and the definition of bioactive constituents. In the present study, we tested the biostimulant proprieties of a sedimentary shale ore-extracted humic acid (HA) on Micro Tom tomato plants under increasing nutritional stress and investigated the correlation with the chemical features of HA by means of ultra-high resolution FT-ICR MS, FT-ATR, and 13C-NMR. Humic acid application proved effective in alleviating the nutritional stress by improving nutrient use efficiency, with results comparable to the control treatment supplied with higher NPK nutrition. Increased yield (up to +19%) and fruit quality (in the range +10–24%), higher ascorbic acid content and a better root growth were the main parameters affected by HA application. Molecular-level characterization identified the possible chemical drivers of bioactivity, and included flavonoids, quinones, and alkaloids among the most represented molecules, some of which exhibiting antioxidant, pro-oxidant, and antimicrobial activity. The redox effect was discussed as a determinant of the delicate homeostasis balance, capable of triggering plant defense response and eventually inducing a protective priming effect on the plants.

“…The intensive selection for tomato lycopene content has been performed. With adequate selection of the lines that will be used in hybrid development, it is expected that in process of the gene recombination we will get the most favorable nutritive contents ratio -especially antioxidants, with a particular emphasis on a lycopene (ZDRAVKOVIC et al, 2002a(ZDRAVKOVIC et al, , 2003c(ZDRAVKOVIC et al, , 2007.…”

“…Breeding for this trait in this manner are in opposite to the selection requirements for organic production. Fruits with greater firmness can be selected by accumulating firmness traits (ZDRAVKOVIC et al, 2007(ZDRAVKOVIC et al, , 2008. Genotypes with "fruit firmness" gene cause long shelf life of mature tomato.…”
