000916748 520__ $$aAbiotic stresses are usually considered as limiting factors in the horticultural production of bell pepper. However, the enhancing effect of abiotic stress on the biosynthesis of plant secondary metabolites bears the potential for production of valuable bioactive plant compounds via targeted application of abiotic stress. At the end of the annual production cycle of bell pepper, high amounts of residual leaf material remain in the greenhouse. Since bell pepper leaves are known to contain pharmaceutically interesting compounds like the flavonoids cynaroside and graveobioside A (Ellenberger et al., 2020), the residual foliar plant material represents a potential source for valuable metabolites, which could be extracted following the horticultural production of fruits. However, the concentration of those metabolites is often too low for an economically feasible extraction. Therefore, the interdisciplinary project TaReCa aimed at increasing the biosynthesis of those valuable metabolites via application of abiotic stress.To identify suitable abiotic stresses strongly triggering the accumulation of the target flavonoids cynaroside and graveobioside A, various stress treatments (e.g. salinity, temperature stress, UV stress, nitrogen deficiency) were applied in different durations, intensities, and combinations to young bell pepper and chilli plants. Throughout treatments, stress responses of plants were monitored noninvasively using phenotyping methods based on leaf colour, fluorescence, and reflectance to develop an easy-to-use method to predict changes in the leaf content of target flavonoids in production greenhouses. With a combination of salt and moderate cold stress, we were able to increase the target metabolites graveobioside A and cynaroside 3.6- and 23-fold in bell pepper leaves of young plants reaching comparable or even higher concentrations than those described for plants commonly used as sources for these metabolites. This novel approach of valorization of horticultural plant residuals has the potential to add value to the bell pepper production.
