Název v původním jazyce
Induction of phenolic metabolites and physiological changes in chamomile plants in relation to nitrogen nutrition
Popis výsledku v původním jazyce
Alternative tools, such as the manipulation of mineral nutrition, may affect secondary metabolite production and thus the nutritional value of food/medicinal plants. We studied the impact of nitrogen (N) nutrition (nitrate/NO3- or ammonium/NH4+ nitrogen)and subsequent nitrogen deficit on phenolic metabolites and physiology in Matricaria chamomilla plants. NH4+-fed plants revealed a strong induction of selected phenolic metabolites but, at the same time, growth, Fv/Fm, tissue water content and soluble protein depletion occurred in comparison with NO3--fed ones. On the other hand, NO3--deficient plants also revealed an increase in phenolic metabolites but growth depression was not observed after the given exposure period. Free amino acids were more accumulated in NH4+-fed shoots (strong increase in arginine and proline mainly), while the pattern of roots' accumulation was independent of N form. Among phenolic acids, NH4+ strongly elevated mainly the accumulation of chlorogenic acid. Wit
