Genotype and harvesting period effects on nutritional components of two cherry tomatoes

Abstract

Many factors that influence the nutritional components of cherry tomatoes have been reported in the literature. The aim of this study was to investigate the effect of genotype and harvesting period on nutritional components (dry matter, total soluble solids, lycopene, p-carotene and total phenols). Cherry tomatoes ('Lipso' F-1 and 'Genio' F-1) were grown hydroponically in a heated glasshouse from mid-February to end-June 2013. From each genotype, fruit samples at the red ripening stage, according to the USDA classification, were taken at 10 and 30 days from the beginning of harvest for the nutritional components determination. The results showed that lycopene and 3 carotene were affected mainly by genotype, while dry matter and total soluble solids by harvesting period. On the other hand, neither genotype nor harvesting period had an appreciated effect on total phenols. 'Lipso' accumulated more lycopene: 22.1 mu g g(-1) fresh weight (FW) and less 3-carotene (14.9 mu g g(-1) FW) than 'Genio' (19.6 and 17.0 mu g g(-1) FW, for lycopene and beta-carotene, respectively). Dry matter and total soluble solids were higher at the second harvest (9.6% FW. and 9.5%, respectively) than the first one (8.5% FW and 8.1%, respectively). For both genotypes, the dry matter content was linearly correlated with total soluble solids (r=0.84, P < 0.001).
