On VW infection, the average total polyphenols content decreases in susceptible hop Celeia and resistant hop Wye Target. Sampling of VW-infected (4 weeks after inoculation) and healthy plants was performed in triplicate at the leaf developmental stage (BBCH 17–19). Total polyphenols were determined spectrophotometrically as described in [43]. Verticillium nonalfalfae (isolate T2; lethal pathotype PV1) was used as the inoculum for root dipping [44]. Data are means ± SE (n = 3).
