“…In addition to visible light, UV‐B exposure also significantly affects carotenoid biosynthesis and accumulation in vegetables. Perez et al found that β ‐carotene accumulation was increased in tomato fruit when it was exposed to UV‐B before harvest. In 2009, Becatti et al studied the effects of pre‐harvest UV‐B exposure on the carotenoid accumulation in tomato fruit and found that removal of UV‐B from solar radiation led to a significant increase in β ‐carotene levels and a decline of approximately 56% in the lutein concentration in mature green tomato fruit, whereas UV‐B removal resulted in an increase of approximately 75% in the lutein concentration in ripe red tomato fruit.…”

Phytochemicals in vegetables are important for human health, and their biosynthesis, metabolism and accumulation are affected by environmental factors. Light condition (light quality, light intensity and photoperiod) is one of the most important environmental variables in regulating vegetable growth, development and phytochemical accumulation, particularly for vegetables produced in controlled environments. With the development of light-emitting diode (LED) technology, the regulation of light environments has become increasingly feasible for the provision of ideal light quality, intensity and photoperiod for protected facilities. In this review, the effects of light quality regulation on phytochemical accumulation in vegetables produced in controlled environments are identified, highlighting the research progress and advantages of LED technology as a light environment regulation tool for modifying phytochemical accumulation in vegetables.

“…Tomato fruits cv. Liberto were subjected to UV-B radiation before harvest with an UV-B dosage of 0.075 and 0.15 Wh m − 2 after different adaptation times of 22 and 44 h, the concentrations of carotenoids, lycopene and β-carotene, in ripe tomato fruits were higher increased by an UV-B dosage of 0.075 Wh m −2 after 22 h of adaptation time [119].…”

Elicitation is a good strategy to induce physiological changes and stimulate defense or stress-induced responses in plants. The elicitor treatments trigger the synthesis of phytochemical compounds in fruits, vegetables and herbs. These metabolites have been widely investigated as bioactive compounds responsible of plant cell adaptation to the environment, specific organoleptic properties of foods, and protective effects in human cells against oxidative processes in the development of neurodegenerative and cardiovascular diseases and certain types of cancer. Biotic (biological origin), abiotic (chemical or physical origin) elicitors and phytohormones have been applied alone or in combinations, in hydroponic solutions or sprays, and in different selected time points of the plant growth or during post-harvest. Understanding how plant tissues and their specific secondary metabolic pathways respond to specific treatments with elicitors would be the basis for designing protocols to enhance the production of secondary metabolites, in order to produce quality and healthy fresh foods.

“…Recent studies have highlighted that ecologically relevant low UV-B levels can trigger the induction of phenolic compounds and the accumulation of carotenoids and GS (e.g. Huyskens-Keil et al 2007 , Perez et al 2009 , Schreiner et al 2009 ). GS and their hydrolysis products are known to have a function in plant resistance against insects and pathogens ( Mewis et al 2005 , Halkier and Gershenzon 2006 , Mewis et al 2006 , Kim and Jander 2007 , Clay et al 2009 ).…”

Only a few environmental factors have such a pronounced effect on plant growth and development as ultraviolet light (UV). Concerns have arisen due to increased UV-B radiation reaching the Earth’s surface as a result of stratospheric ozone depletion. Ecologically relevant low to moderate UV-B doses (0.3–1 kJ m–2 d–1) were applied to sprouts of the important vegetable crop Brassica oleracea var. italica (broccoli), and eco-physiological responses such as accumulation of non-volatile secondary metabolites were related to transcriptional responses with Agilent One-Color Gene Expression Microarray analysis using the 2×204 k format Brassica microarray. UV-B radiation effects have usually been linked to increases in phenolic compounds. As expected, the flavonoids kaempferol and quercetin accumulated in broccoli sprouts (the aerial part of the seedlings) 24 h after UV-B treatment. A new finding is the specific UV-B-mediated induction of glucosinolates (GS), especially of 4-methylsulfinylbutyl GS and 4-methoxy-indol-3-ylmethyl GS, while carotenoids and Chl levels remained unaffected. Accumulation of defensive GS metabolites was accompanied by increased expression of genes associated with salicylate and jasmonic acid signaling defense pathways and up-regulation of genes responsive to fungal and bacterial pathogens. Concomitantly, plant pre-exposure to moderate UV-B doses had negative effects on the performance of the caterpillar Pieris brassicae (L.) and on the population growth of the aphid Myzus persicae (Sulzer). Moreover, insect-specific induction of GS in broccoli sprouts was affected by UV-B pre-treatment.
