“…Results obtained as part of this study confirm previous observations showing that UV-C light, either under the form of exposures of 60 s or of 1s (Fig 4), can stimulate plant defences [6][7][8][9][10][11]. See also Terry and Joyce for older references [17].…”

“…UV-B light is known to act through signalling pathways, involving notably mitogen-activated protein kinases, which closely resemble those for pathogens [5]. It has also been observed that UV-C light can stimulate plant and crop defences against Botrytis cinerea and Sclerotinia minor [6][7][8][9][10][11]. UV-B light requires extensive periods of irradiation (several hours or days) to be effective.…”

Leaves of lettuce, pepper, tomato and grapevine plants grown in greenhouse conditions were exposed to UV-C light for either 60 s or 1 s, using a specific LEDs-based device, and wavelengths and energy were the same among different light treatments. Doses of UV-C light that both effectively stimulated plant defences and were innocuous were determined beforehand. Tomato plants and lettuce plants were inoculated with Botrytis cinerea, pepper plants with Phytophthora capsici, and grapevine with Plasmopara viticola. In some experiments we investigated the effect of a repetition of treatments over periods of several days. All plants were inoculated 48 h after exposure to the last UV-C treatment. Lesions on surfaces were measured up to 12 days after inoculation, depending on the experiment and the pathogen. The results confirmed that UV-C light stimulates plant resistance; they show that irradiation for one second is more effective than irradiation for 60 s, and that repetition of treatments is more effective than single light treatments. Moreover a systemic effect was observed in unexposed leaves that were close to exposed leaves. The mechanisms of perception and of the signalling and metabolic pathways triggered by flashes of UV-C light vs. 60 s irradiation exposures are briefly discussed, as well as the prospects for field use of UV-C flashes in viticulture and horticulture.

“…This emission type comprises the portion of solar radiation that has wavelengths between 100 nm and 400 nm, encompassing between 7% and 9% of the total that reaches the surface of the Earth (Bornman et al, 2015). Three types of UV radiation can be distinguished based on their energy and biological activities which correspond to three wavelength ranges (Forges et al, 2018). The first, UV‐A (between 320 nm and 400 nm) easily penetrates the atmosphere and is a major component of radiation in sunlight (de Gruijl & Leun, 2000).…”

Ultraviolet (UV) radiation is a major environmental stress factor for many organisms and is known to exert a wide range of hazardous effects (Meyer-Rochow, 2000;Schauen et al., 2007). This emission type comprises the portion of solar radiation that has wavelengths between 100 nm and 400 nm, encompassing between 7% and 9% of the total that reaches the surface of the Earth (Bornman et al., 2015). Three types of UV radiation can be distinguished based on their energy and biological activities which correspond to three wavelength ranges (Forges et al., 2018). The first, UV-A (between 320 nm and 400 nm) easily penetrates the atmosphere and is a major component of radiation in sunlight (de Gruijl & Leun, 2000). The second, UV-B (between 280 nm and 320 nm) is only partially absorbed by atmospheric ozone and comprises approximately 4% of terrestrial

“…Ultraviolet radiation to low levels for treatment of seeds is an ecologically safe method, then, an environmentally-friendly alternative to improve plant productivity, yield quality and as well as to induce tolerance of plants to various biotic and abiotic stresses (Forges et al 2018;Thomas and Puthur, 2016;Ehsanpour and Razavizadeh 2005). UV light is an electromagnetic radiation of wavelengths shorter than the visible region, but longer than X-rays (Shetta and Areaf 2009).…”

We quantitatively evaluate the effects of UV-C radiation on bean seeds Oti (Phaseolus vulgaris), their germination and phenolic compounds of seedlings, by means of photoacoustic spectroscopy and scanning electron microscopy. It is shown that: i) The photoacoustic signal produced by the bean seeds exposed to UV-C radiation during 15 minutes, reduces from 0.24 to 0.10 mV for the wavelengths of 295 and 340 nm, as a result of their degradation. This significant reduction of 58.3% decreases, but keeps over 50% for other spectral UV wavelengths within the interval (270-400 nm). ii) As the UV-C radiation time increases from 2 to 15 min, the morphological changes at the surface of the bean seeds exhibits micro-holes and detachment of the cotyledon sclereids. iii) There are no significant statistical differences in the variables of germination, dry weight and seedling length, for exposure times up to 15 minutes. iv). The phenolic acids and flavonoids of the bean seedlings of seeds treated by UV-C for different exposure times (0, 2, 5, 10 and 15 min) display significant statistical differences (P ≤ 0.05) in both roots and foliage. For both the roots and foliage, the highest concentration of phenolic acids is observed at 10 and 15 minutes, while for root flavonoids, it appears at 5 and 15 minutes.
