“…The color of fruits and vegetables is a key and critical factor to consumer acceptance and the marketing success of these products, and it is dependent on light irradiation intensity (Gironi and Testoni, 1990; Kays, 1999; Schreiner et al, 2002). Since the primary pigments conferring colorful features to these agri-food commodities are chlorophylls (green), carotenoids (yellow, orange, and red), anthocyanins (red, blue), and flavonoids (yellow), there is an intrinsic association between the color, texture, and nutritional composition of fruits and vegetables (Barrett et al, 2010).…”

The quality of horticultural products is the result of the interaction of different factors, including grower’s crop management ability, genotype, and environment. Sub-optimal environmental conditions during plant growth can induce abiotic stresses and reduce the crop performance with yield reduction and quality losses. However, abiotic stresses can induce several physiological, biochemical, and molecular responses in plants, aiming to cope with the stressful conditions. It is well known that these abiotic stresses are also elicitors of the biosynthesis of many metabolites in plants, including a wide range of bioactive compounds, which firstly serve as functional molecules for crop adaptation, but they have also a great interest for their beneficial effects on human health. Nowadays, the consumer is oriented to low-energy foods with low fat content, but at the same time, growing attention is paid to the presence of bioactive molecules, which are recognized as health-related compounds and concur to the nutraceutical value of plant-derived foods. In this context, fruit and vegetables play an important role as sources of bioactive ingredients in the diet. At the cultivation level, the understanding of crop responses to abiotic stresses and how they act in the biosynthesis/accumulation of these bioactive compounds is crucial. In fact, controlled abiotic stresses can be used as tools for improving the nutraceutical value of fruit and vegetables. This review focuses on the quality of vegetables and fruits as affected by preharvest abiotic stressors, with particular attention to the effect on the nutraceutical aspects.

“…w 1.0 ton/acre = 2.24 t•ha -1 . v Numbers in a column followed by the same letter exhibited no signifi cant differences based on Duncan's multiple range test where P = 0.05. previous trials (Dainello et al,1984;Gorini and Testoni, 1990) were rated for color, recent work by Morelock (1999, 2000) indicate that high levels of green color intensity may be linked to higher levels of lutein. This may very well make leaf color ratings an important aspect of spinach cultivar testing in the future, particularly as consumers become more conscious of the nutritional value of their food.…”

“…Numerous aspects of spinach production have been evaluated in cultivar trials, including emergence, yield, growth habit, color intensity, bolting, and pest resistance (Dainello, 1989;Dainello et al, 1987;De Rooster and Spiessens, 1998;Djurovka et al, 1988;Gorini and Testoni, 1990;Sneep, 1982). Crop emergence is an important aspect of production.…”

“…Spinach color intensity has been an important aspect of testing for several investigators (Dainello et al, 1984;Gorini and Testoni, 1990;Tonini et al, 1987). Dark green color is considered an important attribute that consumers utilize when selecting either fresh or frozen spinach (Gorini and Testoni, 1990). Murphy and Morelock (1999) noted that dark green vegetables have high levels of carotenoids.…”

Nine (2001) and eight (2002) spinach (Spinacia oleracea) cultivars, including hybrid and open pollinated types, were tested for yield and quality characteristics during two spring production seasons in Oklahoma. Cultivars were evaluated for emergence, vigor, color, bolting resistance, and yield. Cultivars did not vary significantly for yield, which ranged from 11.9 to 14.9 tons/acre. `Baker', `Bolero', `Catalina', `Olympia', and `Padre' had significantly higher levels of bolting resistance than other cultivars in the trials. 'Catalina', `Olympia', and `Padre' also exhibited the darkest green color of those cultivars with bolting resistance. Based upon bolting resistance, `Catalina', `Olympia', `Padre', `Baker', and `Bolero' are five cultivars that can be recommended for use in spring planted spinach in Oklahoma and the southern plains.

Consumer demands become increasingly strong in Western countries . Product quality has proven to be an important marketing tool to compete effectively on these saturated markets . Markets in developing countries are mostly producer dominated . Not much attention is paid to product quality. Agricultural researchers traditionally are producer-oriented, rather than consumer-oriented . Research on tomatoes in Indonesia has shown, that even in producer dominated markets, consumers have specific wishes regarding quality, which should be taken into consideration in order to develop demand and to enhance farmers' profitability . This paper sheds light on a research methodology to translate consumer preferences into an ideotype, a practical product profile consisting of optimal levels of relevant physical and chemical properties . This ideotype should be used to objectively evaluate agricultural research, aimed at improving product quality . In addition, a list of quality problems of current supply is presented . This priority list serves as a guideline for research planning . Finally, a method is presented to find out to what extend consumers are willing to pay a higher price for improved quality.
