EFFECT OF ABIOTIC ELICITORS ON ANTHOCYANIN PRODUCTION IN BERRY CELL SUSPENSIONS
Berry species are important sources of polyphenols with antioxidant properties and great attention has been focused on those compounds for their pharmacological potential. The main focus of this study was to determine the in vitro conditions affecting anthocyanin concentration in cell suspension cultures of strawberry (Fragaria × ananassa Duch.), blackberry (Rubus fruticosus L.), red raspberry (Rubus idaeus L.) and strawberry-tree (Arbutus unedo L.). We used as elicitors: temperature, light (blue or red spectra) and changes of medium composition, i.e., increased nitrogen concentration. Anthocyanin production was significantly increased only by elicitation with light, either blue or red spectra, in blackberry and strawberry-tree cultures, and particularly red light in strawberry. In red raspberry cultures anthocyanin accumula¬tion was not affected by any elicitor.
