One of the objective of the QualiRedFruits project was to analyse the influence of biotisation with Glomus intraradices isolate LPA8 and Sinorhizobium meliloti, production site (Switzerland France, Slovenia, Bulgaria) and cultivar ('Tulameen', 'Polka') on antioxidant molecules (AOM) content and antioxidant activities in raspberry fruits. 'Polka' was significantly richer in anthocyanins and showed much higher ORAC values than 'Tulameen', whereas for total phenolic content and FRAP values no differences were observed between both cultivars. Growing location significantly influenced AOM content and antioxidant capacities of raspberry fruits for both cultivars with, in general, fruits from soil production systems showing the higher contents of health related compounds than production systems on substrate. However, the treatments with and without biotisation showed no clear differences on AOM production and antioxidant activities in fruits at each location due to high natural colonisation by indigenous mycorrhizal fungi. In conclusion, the most important factors influencing AOM content and antioxidant activities in raspberry fruits in this experiment were the plant genotype (cultivar) and to a lesser extent the production site.
