“…In addition, without further analyses, we do not know whether these color differences reflected significant differences in nutritional value or other quality parameters. In at least one study, ultraviolet radiation was found to speed the rate of color development, which was also correlated with an increase in fruit anthocyanin, flavonoid, and phenolic contents at harvesting (Tsormpatsidis et al, 2011). Temperature may also play a role.…”

“…Total soluble solid content may be affected by the amount and quality of light a plant receives (Perkins-Veazie, 1995). Some studies have shown that fruit color and plant growth may be negatively affected by restricted ultraviolet exposure (Elfadly et al, 2012;Tsormpatsidis et al, 2011). And there is evidence suggesting that exposure to ultraviolet light improves crop resilience in the face of environmental stressors by way of photoreceptors that trigger critical defense mechanisms (Ballar e et al, 2012;Wargent et al, 2011).…”

Consumer demand for local and organic strawberries (Fragaria ×ananassa) is increasing. Growers who can meet this demand have a competitive edge in the direct-to-consumer market. Innovations in strawberry production for northern climates offer new opportunities for growers to meet the demand for local organic strawberries. Typically adopted for season extension, the use of poly-covered tunnels for crop protection provides other benefits including protection from adverse weather. Low tunnels are easy to install, low cost, temporary protective structures that are well-adapted for annual day-neutral strawberry production, and they are more space efficient than high tunnels for these low-stature crops. A range of specialty tunnel plastics that modify and diffuse light are available, but there is little information on how these influence strawberry plant growth and performance in the field. Our objectives were to determine the effects of experimental ultraviolet blocking and transmitting plastics on light and microclimate in low tunnel environments and assess differences in fruit yield and quality in the day-neutral strawberry cultivar Albion in an organic production system. This research was conducted on U.S. Department of Agriculture-certified organic land over 2 years, in 2016 and 2017. We found that ultraviolet intensity and daily light integral (DLI) were lower in covered plots than in the open field. Maximum daily temperatures were slightly higher in covered plots. Both ultraviolet-blocking and ultraviolet-transmitting plastics improved marketable fruit yield compared with the open-field control. Strawberries grown in the open-field treatment were lower in chroma than covered plots in 2017, and there was no difference in total soluble solids between treatments in either year. Low tunnel systems allow for increased environmental control and improved fruit quality and are well-adapted for day-neutral organic strawberry production systems.

“…UV-C treatment has been associated with enhancement of bioactive compounds, such as vitamins, carotenoids and phenolic compounds, in several fruits and vegetables, e.g. tomatoes (Jagadeesh et al 2011;Maharaj et al 2014), strawberries (Pombo et al 2009;Tsormpatsidis et al 2011 (Bravo et al 2013). An important flavonoid phenolic compound in tomato is the flavonols, which are restricted almost entirely in the skin.…”

The effect of UV-C treatments (0.32, 0.97, 2.56, 4.16 and 4.83 kJ.m(-2) at 254 nm) on the physical-chemical properties [colour, texture, total phenolic content (TPC), weight loss (WL)], and mesophylic counts of whole tomato, was evaluated during 15 days at 10 °C. During storage, the Ctr samples acquired faster red colour than all UV-C samples (higher a* and lower °h values). Comparing texture of Ctr and UV-C samples at 15(th) storage day, an increase of 9 and 8 % on firmness of treated samples at low UV-C intensities (0.32 and 0.97 kJ.m(-2), respectively) was observed. At the end of the storage, Ctr samples showed ca. 4 Log10 of mesophylic load, and the samples treated at 0.97 and 4.83 kJ.m(-2) revealed the lowest microbial load (1.9 and 3.2 Log10, respectively). These results indicate that UV-C radiation, at an appropriate dose, combined with low storage temperature (10 °C) are an effective method to preserve the postharvest life of tomato, without adversely affecting quality parameters.

“…Anthocyanin levels in ripe strawberries have been shown to be influenced by environmental factors including temperature,13 carbon dioxide concentration14 and growing media 15. Previously we have found the levels of phenolic compounds in strawberry crops to be, overall, unresponsive to alterations in UV caused by differentially UV‐screening films;16 other studies, however have found effects of UV on specific individual phenolic compounds17 and when plants have been studied at a detailed and standardised physiological level,18 but the effect of UV on colour development of strawberry fruit grown under near‐commercial conditions has not been previously reported.…”
