“…For shoot height, the results after irradiation with UV-C and culturing on MS basal medium for 8 weeks showed that both single low-and high-intensity UV-C exposures conferred higher shoot length compared to the control (Table 3). This finding is dissimilar to that in tomato plants grown inside a greenhouse, for which the plant height was notably reduced after irradiation with 1.0 or 2.5 kJ/m 2 UV-C [33]. Therefore, UV-C might only improve plant height in certain species.…”

Persian violet flowers are considered esthetically attractive, leading to the high economic value of this plant. Plant breeding is fundamental to crop improvement, and the induction of mutation by tissue culture technology in combination with irradiation has been beneficially applied to generate plants with novel desirable characteristics. In this research, single or double rounds of UV-C irradiations were carried out on plant tissue cultures to initiate the in vitro rooting and mutation of Persian violets. It was found that single low-intensity UV-C exposure, when applied to Persian violet microshoots for 4 h, could induce the maximum number of roots and the highest root length without the use of a plant growth regulator. Overall, the single and double UV-C irradiation of Persian violet microshoots led to 44 different types of Persian violet flower mutations. Under single high-intensity UV-C irradiation for 6 h, up to nine petals were initiated, whereas single low-intensity UV-C irradiation did not influence the morphological variation of Persian violet flowers. Thus, Persian violet microshoots respond differently in terms of in vitro rooting and flowering depending on the UV-C intensity and exposure duration. These outcomes may be applied to micropropagation and in vitro plant breeding.

“…On the other hand, similar to our results, Seven et al ( 2015 ) revealed that 260-nm UV-C radiation administration resulted in a remarkable decrease in germination percentage, weight gain, and root length in A. cepa . According to Darras et al ( 2020 ), while low doses of UV-C radiation cause positive physiochemical changes in the plant, high doses of UV-C exposure cause many growth-restricting changes such as the destruction of photosynthetic pigments and photosystem II damage. Lycopene reduced UV-mediated growth arrest in a dose-dependent manner.…”

“…In studies by Liu et al [ Recent studies have evaluated the effects of UV-C on plant growth and photosynthesis. A positive effect of UV-C was found by Darras et al [38] on 'Belladona F1' tomato (Solanum lycopersicum) plants. Irradiated with UV-C at 1.0 kJ m −2 , the plants showed a 25% increase in total fruit number and a 36% increase in fruit weight compared to non-irradiated controls.…”

“…Other evidence from the same experiment showed that pulsed UV-C irradiation induced changes in growth and fruit set in 'Belladonna F1' tomato plants. This higher yield of tomatoes may be due to shared UV-B photoreceptors also absorbing UV-C light [21], as occurs in some photomorphogenic reactions, promoting an increase in biomass [38].…”

Ultraviolet (UV) is a component of solar radiation that can be divided into three types defined by waveband: UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (<280 nm). UV light can influence the physiological responses of plants. Wavelength, intensity, and exposure have a great impact on plant growth and quality. Interaction between plants and UV light is regulated by photoreceptors such as UV Resistance Locus 8 (UVR8) that enables acclimation to UV-B stress. Although UV in high doses is known to damage quality and production parameters, some studies show that UV in low doses may stimulate biomass accumulation and the synthesis of healthy compounds that mainly absorb UV. UV exposure is known to induce variations in plant architecture, important in ornamental crops, increasing their economic value. Abiotic stress induced by UV exposure increases resistance to insects and pathogens, and reduce postharvest quality depletion. This review highlights the role that UV may play in plant growth, quality, photomorphogenesis, and abiotic/biotic stress resistance.
