Amounts of Organic Constituents in Tomato Cultivated in Open and Closed Hydroponic Systems

Production Practices and Quality Assessment of Food Crops Volume 1

“…These results support a role for hydroxycinnamate-tyramine conjugates as part of the defence system of the plant (Pearce et al, 1998). Tomatoes grown on the soil system contained significantly lower amounts of ascorbic acid and carbohydrates compared to the hydroponic systems (Lippert, 1993). Contents of β-carotene and lycopene in five maturity stages of tomatoes grown in field, under glass or under plastic foil (modified from (Cabibel and Ferry, 1980)) The substrate system is another factor investigated on its influence on tomato ingredients.…”

Effect of organic growing systems on sensory quality and chemical composition of tomatoes

“…The levels of pH, dry matter, soluble solids, titratable acidity and vitamin C in the organic tomatoes grown in soil and compost (Table 4) were within the levels reported for conventional tomatoes grown in soil and on rock-wool slab (Lippert, 1993;Petersen et al, 1998;Tando et al, 2003). The tomatoes were firmer in 2002 than in 2003 (Table 4), which reflected that the tomatoes were harvested at a stage of advanced ripeness and higher maturity in 2003.…”

Application of agglomerative hierarchical clustering to identify consumer tomato preferences: influence of physicochemical and sensory characteristics on consumer response

“…the development of Aranka and Pitenza on the vine, and Cherry). 8 Several studies have shown that there are no differences in the physicochemical parameters of tomatoes cultivated with or without soil 9 and that consumers cannot distinguish between the quality of the resulting fruit. 10 Studies have also shown there are no quality differences between tomatoes produced in a greenhouse and those grown in the field.…”
