Total Phenolic Content (TPC) and Total Antioxidant Capacity (TAC)
The effects of the fertilizer and cultivar, as well as their interactions on the total phenolics
and antioxidant capacity in cvs 'Clery', 'Joly' and 'Dely' are shown in Table 7 and Figures 5
and 6.
The highest TPC (301.5 mg/100 g FW) as well as TAC (482.8 Trolox, mmol/100g FW)
were observed in the biofertilizer treatments. Significant differences in the levels of TPC were
also determined between the cultivars with the highest and lowest content.
