The P values of main and interaction effects for tomatoes
are given in Table 1. The main factor year (Y) had the greatest influence on the content of percent soluble solids, quercetin,
kaempferol, and ascorbic acid and the Hunter a/b ratio. Cultivar
(C) was significant (P < 0.05) for quercetin, kaempferol (DWB),
ascorbic acid, and the Hunter a/b ratio. The cropping system
(CS) was significant for percent soluble solids, quercetin (FWB),
kaempferol (FWB), and ascorbic acid (FWB). No interactive
effects were observed for cropping system and cultivar (CS ×
C). Interactive effects between cropping system and year (CS
× Y) were significant for percent soluble solids, quercetin, TP
(DWB), and ascorbic acid. Interactive effects between cultivar
and year (C × Y) were significant for percent soluble solids,
quercetin, TP (FWB) and ascorbic acid.
