“…1) and cladophylls appear, thus increasing the ratio of epidermis to spear volume, which may be responsible for the increased rutin content. Previous reports indicate that the rutin content of asparagus is reduced by shading (Kohmura et al, 2008). In addition, Maeda (2008) suggests that rutin plays a role in the antioxidant defense against solar ultraviolet radiation.…”

Head tightness, soluble solid content (SSC), and rutin level were investigated in asparagus spears harvested at different lengths. We found no correlation between spear length and SSC per dry weight (DW) in spearheads. Spearheads became looser and the rutin content of the spearhead increased as spear length at harvest increased, although appearance quality decreased. These findings revealed that spears previously discarded, because their length did not meet the length specifications, contained abundant rutin. Therefore, spears for which the optimum harvesting time has been missed are a useful rutin source.

“…In green asparagus, the chlorophyll, ascorbic acid, and rutin (the main flavonoid with strong antioxidant properties, in asparagus, quercetin-3- O -beta-rutinoside), and in purple asparagus, the anthocyanin content, were shown to be positively dependent on light intensity (Guillén et al, 2008; Kohmura et al, 2008; Maeda et al, 2008, Maeda et al, 2010; Wambrauw et al, 2016). When light is under optimal level, the overall color and nutritional quality were negatively affected, the concentration of rutin decreased, and the spear color was pale (Wambrauw et al, 2016).…”

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.

“…Since rutin is produced as an environmental response to light exposure (Suzuki et al 2005;Kohmura et al 2008), and previous studies have suggested an environmental component to variation Stoffyn et al 2012), moderate heritability may not be unexpected. Improved estimates may be possible in future experiments by decreasing diameter and tip tightness variation among spears, harvesting spears of an exact length measured from the ground, rather than collecting spears of variable size and trimming to 23 cm, and increasing replication.…”

2014. Genetic variation and heritability of rutin and glutathione concentrations in asparagus spears. Can. J. Plant Sci. 94: 1355Á1362. Asparagus (Asparagus officinalis L.) spears contain numerous phytochemicals, including rutin (a flavonoid) and glutathione (a biothiol), that are beneficial to human health due to antioxidant or other activities. To assess the potential to increase phytochemical content through breeding, genetic variability was surveyed in diverse germplasm adapted to southern Ontario. Selected female and supermale genotypes were also hybridized in a partial diallel to estimate heritability and identify parents with good combining ability. Genetic variation for rutin (3.30 to 8.14 mg g (1 dry weight) was observed, while glutathione concentrations (5.37 to 7.86 mmol g (1 dry weight) did not differ significantly among tested genotypes. Combining ability effects were significant for rutin concentration and heritability was also moderate. From these results, breeding to improve the concentration of rutin, rather than that of glutathione, is most achievable in the germplasm tested. Drinkwater, J. M., Tsao, R., Liu, R. et Wolyn, D. J. 2014. Variation ge´ne´tique et he´ritabilite´de la concentration de rutine et de glutathion dans les turions d'asperge. Can. J. Plant Sci. 94: 1355Á1362. Les turions d'asperge (Asparagus officinalis L.) renferment de nombreux compose´s phytochimiques be´ne´fiques pour la sante´humaine en raison de leur pouvoir antioxydant et d'autres proprie´te´s. La rutine (un flavonoı¨de) et le glutathion (un biothiol) en sont deux exemples.Pour de´terminer si on pourrait accroıˆtre la concentration de ces compose´s par l'hybridation, les auteurs en ont examine´la variabilite´ge´ne´tique chez des varie´te´s acclimate´es au sud de l'Ontario. Ils ont aussi hybride´quelques ge´notypes femelles et super maˆles dans le cadre d'un croisement dialle`le partiel et identifie´les parents qui pre´sentaient une bonne aptitude a`la combinaison. La concentration de rutine varie ge´ne´tiquement (de 3,30 a`8,14 mg par gramme de poids sec), mais celle de glutathion (de 5,37 a`7,86 mmol par gramme de poids sec) ne diffe`re pas de manie`re significative entre les ge´notypes teste´s. L'aptitude a`la combinaison a des effets significatifs sur la concentration de rutine, dont l'he´ritabilite´est moyenne. D'apre`s ces re´sultats, on conclut que l'hybridation du mate´riel ge´ne´tique teste´se preˆte mieux a`une ame´lioration de la concentration de rutine que de celle du glutathion.
