“…The TPC increased with the storage time, of 148.9 and 127.8 mg GAE kg −1 for the red and green LED exposed bananas, respectively, on day 8, which were 27% and 9.2%, respectively, higher than that of the control group. These results agree with the studies that investigated the effect of different LED wavelengths on accumulation of phenolic compounds in postharvest strawberry, and cabbage …”

“…Besides, green light may participate in reactions not directly exposed to the light stimulus, as it is efficiently transmitted through the plant tissues . Previous studies have also shown that green light treatments improved the sugar content of stored strawberries.…”

“…Although the studies on light emitting systems for plant growth are on going, the effects of LED lighting during storage of vegetables and fruit after harvest are relatively less studied in the literature. LED irradiation has been shown to be effective for enriching the nutritional value and quality of non‐climacteric fruit, such as citrus fruit, and strawberries . Other studies have reported that exposure to LED light extended the shelf‐life of climacteric crops, including tomato, and broccoli, by delaying their ripening and senescence after harvest.…”

“…Also in baby leaf lett uce, Li and Kubota (11) showed an increase in TPC aft er exposure to LED light from 600 to 700 nm. Using LED light at 470 nm, Kim et al (36) reported signifi cantly higher TPC in strawberry fruit, and as reported by Zhan et al (41), storage of broccoli under fl uorescent light increased TPC.…”

SummaryThe objective of this study is to investigate the eff ects of irradiation from light-emitt ing diodes (LEDs) on several fruits during storage. To improve storage and increase the contents of some bioactive compounds, apple, tomato and red bell pepper fruits were exposed to yellow light emitt ed from the diodes at 590 nm. The contents of ascorbic acid, total phenolics, total fl avonoids and several pigments were investigated, along with the antioxidant potential. The colour parameters (L*, a* and b*) and fi rmness of the fruit were also determined. Aft er 7 days of LED light irradiation, there was signifi cantly higher total phenolic content and antioxidant potential in apple peel extracts. The irradiated fruit of tomato had signifi cantly higher levels of total phenolic compounds, and the fruit of red bell pepper had signifi cantly higher antioxidant potential. LED light had no eff ects on the colour parameters, although there was a tendency to accelerate colour development. Apple fruit irradiated with LED light was signifi cantly less fi rm. Among twelve analysed pigments, signifi cantly more β-carotene was detected in LED light-irradiated apple and bell pepper fruit, more α-tocopherol and γ-tocopherol in bell pepper fruit, and more lutein in apple peel and bell pepper fruit. The applied LED light slightly accelerated the ripening of the studied fruit, and aff ected the synthesis of some of the secondary metabolites.

Breeding new varieties for controlled environments

Agricultural production in controlled environments is increasingly feasible, and may play an important role in providing nutrition and choice to growing urban centres. New technologies in lighting, ventilation, robotics and irrigation are just a few of the innovations that enable production of high-value specialty crops outside of a traditional field setting. However, despite all of the advances in the hardware within the plant factory operation, innovation of the most complex machine has been neglected - the plant itself. Indoor agricultural operations typically rely on legacy varieties, plants selected and bred for field conditions. In the field, phenotypic stability is paramount, as production must be consistent in an unpredictable and changing environment. However, the controlled environment affords focus on different breeding priorities as environmental flux, pests, pathogens and post-harvest quality are less formidable barriers to production. On the contrary, breeding for controlled environments shifts the focus to a completely different set of plant traits, such as rapid growth, performance in low light environments and active manipulation of plant stature. Instead of breeding for phenotypic stability, plants may be bred to maximise genetic plasticity, allowing specific traits to be presented as a function of the quality of the ambient light spectrum. In this scenario plant varieties may be grown with optimal size, supporting a focus on consumer traits like flavour or accumulation of health-related compounds. Gene editing may be a central technology in the production of designer plants for controlled environments. This review considers the opportunity for breeding for controlled environments, with a focus on a revision of priorities for controlled-environment breeders.
