The accumulation of polyphenols and L
-
ascorbic acid was
evaluated under conventional (integrated pest management, IPM) and
organic farming, as means to increase the accumulation of chemoprotective
compounds. The
effect of genotype was considerably higher than the
growing system, in fact it is determining. 'Kalvert', a high
-
lycopene
cultivar, outstood for the accumulation of most polyphenols, though low
-
carotenoid cultivars with high accumulation were also detected
. Organic
farming significantly increased the levels of caffeic acid by 20%, but
reduced those of ferulic acid and naringenin by 13% and 15% respectively.
A strong interaction with the environment was detected: in Navarra the
differences were limited, whil
e in Extremadura lower contents of ferulic
acid and higher contents of chlorogenic acid and rutin were found in
organic farming for certain cultivars. The effect of organic farming on
L
-
ascorbic acid was dependent on cultivar and environment and it only le
d
to an increase in Extremadura by 58%.
