“…Combining red light with other light qualities or natural light could balance the advantage of red light in improving plant resistance and the potential negative effects on the functioning of the photosynthetic apparatus under monochromatic red light (Meng et al, 2020b). In modern greenhouses and vertical farms, red light can be applied during a specific number of hours in a 24 h light/dark cycle and for several days during the crop production phase.…”

“…Previously, we investigated the effects of a 4 h (at the end of photoperiod) and 12 h red light treatment (at the beginning of photoperiod) in a photoperiod of 16 h given for 2 weeks on leaf resistance to B. cinerea. It turned out that 12 h red light followed by 4 h white light enhanced the leaf resistance of strawberry while four hours of red light had no effect (Meng et al, 2020b).…”

“…Similarly, strawberry ( Fragaria ananassa cv. Elsanta) plants inoculated with B. cinerea developed stronger disease symptoms, if plants were transferred to darkness after infection compared to plants kept under their normal light conditions ( Meng et al, 2020 ). Macioszek et al (2021) observed that growth under short-day conditions results in increased necrosis formation in Brassica juncea plants infected with the necrotrophic fungus Alternaria brassicicola .…”

“…LEDs can also be used for pest management. Several studies showed the influence of the light environment in greenhouses (including the length of the photoperiod and light quality) (for review, see Gallé et al, 2021 ; Lazzarin et al, 2021 ), on plant resilience against pathogens such as B. cinerea in strawberries ( Meng et al, 2020 ) or tomatoes ( Yang et al, 2015 ). Understanding how supplemental light through LEDs acts on plant growth and defense may lead to novel sustainable horticultural methods for pest management.…”

The Photoperiod: Handling and Causing Stress in Plants

The photoperiod, which is the length of the light period in the diurnal cycle of 24 h, is an important environmental signal. Plants have evolved sensitive mechanisms to measure the length of the photoperiod. Photoperiod sensing enables plants to synchronize developmental processes, such as the onset of flowering, with a specific time of the year, and enables them to alleviate the impact of environmental stresses occurring at the same time every year. During the last years, the importance of the photoperiod for plant responses to abiotic and biotic stresses has received increasing attention. In this review, we summarize the current knowledge on the signaling pathways involved in the photoperiod-dependent regulation of responses to abiotic (freezing, drought, osmotic stress) and biotic stresses. A central role of GIGANTEA (GI), which is a key player in the regulation of photoperiod-dependent flowering, in stress responses is highlighted. Special attention is paid to the role of the photoperiod in regulating the redox state of plants. Furthermore, an update on photoperiod stress, which is caused by sudden alterations in the photoperiod, is given. Finally, we will review and discuss the possible use of photoperiod-induced stress as a sustainable resource to enhance plant resistance to biotic stress in horticulture.

“…Previous research has shown that changing light intensity, quality, and photoperiod may alter growth and govern developmental transitions (Meng et al, 2020;Elmardy et al, 2021;Liang et al, 2021;Hamedalla et al, 2022;Malekzadeh Shamsabad et al, 2022). Basic plant research using various light spectrums has shown that well-defined light wavelengths have a significant impact on plant physiology such as germination and stem development (Parks et al, 2001), biomass and flowering transition (Valverde et al, 2004), in the outcome of plant-pathogen interactions (Meng et al, 2020) and an increase in plant resilience under stress conditions (Malekzadeh Shamsabad et al, 2022). Because light regulates plant photomorphogenesis and photosynthesis (Avercheva et al, 2009), it plays a crucial role in the whole plant life cycle.…”

Due to advances in the industrial development of light-emitting diodes (LEDs), much research has been conducted in recent years to get a better understanding of how plants respond to these light sources. This study investigated the effects of different LED-based light regimes on strawberry plant development and performance. The photosynthetic pigment content, biochemical constituents, and growth characteristics of strawberry plants were investigated using a combination of different light intensities (150, 200, and 250 μmol m−2 s−1), qualities (red, green, and blue LEDs), and photoperiods (14/10 h, 16/8 h, and 12/12 h light/dark cycles) compared to the same treatment with white fluorescent light. Plant height, root length, shoot fresh and dry weight, chlorophyll a, total chlorophyll/carotenoid content, and most plant yield parameters were highest when illuminated with LM7 [intensity (250 μmol m−2 s−1) + quality (70% red/30% blue LED light combination) + photoperiod (16/8 h light/dark cycles)]. The best results for the effective quantum yield of PSII photochemistry Y(II), photochemical quenching coefficient (qP), and electron transport ratio (ETR) were obtained with LM8 illumination [intensity (250 μmol m−2 s−1) + quality (50% red/20% green/30% blue LED light combination) + photoperiod (12 h/12 h light/dark cycles)]. We conclude that strawberry plants require prolonged and high light intensities with a high red-light component for maximum performance and biomass production.
