Tailor-made fertilization regimes as strategies to increase phenolic composition: the case study of pot grown Cichorium spinosum L. In 15th World Congress on Polyphenols Applications. Valenciahttp://hdl.handle.net/10198/26358Cichorium spinosum is a perennial halophyte of the Mediterranean basin, consumed for its fresh green leaves.1 It is normally handpicked from the wild, but the cultivated one allows its collection several times per year, resorting to the use of chemical fertilizers.2,3 Needless to say, that the switch to innovative and sustainable farming practices it is of the upmost importance in a world of climate crises, land degradation and, particularly, extreme drought, allowing the production of promising crops with low input requirements, sustainable footprint, and rich in high-added value compounds. In the present work, the individual phenolic profile was obtained by HPLC-DAD/ESI-MSn in the aqueous and hydroethanolic extracts of pot grown C. spinosum plants, non-fertilized and fertilized with different concentrations (mg/mL) of N:P:K nutrient solutions. In both extracts, seven phenolic compounds were found, being p-coumaroylquinic acid and O-glycosylated isorhamnetin derivatives the most abundant. The most important result found was the effect of increasing the nutrients in the obtaining of higher amounts of phenolic acids; while higher amounts of flavonoids were found in more moderate concentrations of nutrients. Tailor-made fertilization regimes can, therefore, be used to implement a production strategy of innovative plants in order to obtain high quality final products.engCichorium spinosumResearch Subject Categories::FORESTRY, AGRICULTURAL SCIENCES and LANDSCAPE PLANNING::Product scienceconference object
