Lettuce is a cool season crop, grown worldwide and important vegetable usually used as a sal-
ad. It is rich in vitamin C, which has significant role as antioxidant, but lettuce can also accumulate
toxic compounds like nitrates. The purpose of this study was to examine the effect of different
lettuce genotypes and growing seasons on the content of nitrate and vitamin C in the outer
and inner leaves. Six cultivars (‘Kiribati’ RZ, ‘Murai’ RZ, ‘Aquino’ RZ, ‘Gaugin’ RZ, ‘Aleppo’ RZ, ‘Carmesi’
RZ) were grown in the greenhouse experiment during autumn, winter and spring. Vitamin C was
determined spectrophotometrically at 550 nm and nitrate colorimetrically at 420 nm. Vitamin C
ranged between 3.64-12.41 mg per 100 g FW in autumn, 3.68-7.34 mg per 100 g FW in winter and
3.05-7.72 mg per 100 g FW in spring. Cultivar ‘Carmesi’ had the highest level of vitamin C in the
outer leaves (9.15 mg per 100 g FW) and ‘Gaugin’ in the inner leaves (12.41 mg per 100 g FW), both
in autumn. Nitrate c...ontent ranged between 258.77-908.2 mg kg-1 FW in autumn, 296.62-977.64
mg kg-1 FW in winter and 42.74-450.74 mg kg-1 FW in spring. Cultivar ‘Carmesi’ had the highest
level of nitrate in the outer leaves (977.64 mg kg -1 FW) and ‘Aleppo’ in the inner leaves (701.45 mg
kg -1 FW), both in winter. Nitrate content in all seasons and genotypes stayed within the limit of EC
regulation for protected lettuce. Generally, vitamin C was allocated to the inner and nitrate to the
outer leaves. Results showed that genotype and growing season can affect the content of vitamin
C and nitrate in lettuce leaves.
