When TEAC data were averaged across sampling areas, the highest HAA was registered in the Crimson Sweet and Giza cvs (290.9 and 271.3 mmol Trolox/100 g fw, respectively), whereas the lowest value was found in P503 cv (182.4 mmol -Trolox/100 g fw). The LAA values were of the same order of magnitude as HAA dwelling in a range of 210.7–258.9 mmol -Trolox/100 g fw, but less variable. Again, Crimson Sweet ranked first among the assayed watermelon cvs, whereas the last position was held by P503 and Aramis cvs (210.7 and 206.0 mM Trolox/100 g fw, respectively).
