“…It may affect photosynthesis and the content of chlorophyll in leaves [ 51 , 56 ]. Pre-sowing UV-C irradiation of wheat seeds may result in seed coat thicknesses that relate to better resistance against pathogens [ 51 ]. Most of the studies have focused on post-sowing UV-A/B radiation [ 57 ].…”

Metalloenzymes play an important role in the regulation of many biological functions. An effective way to prevent deficiencies of essential minerals in human diets is the biofortification of plant materials. The process of enriching crop sprouts under hydroponic conditions is the easiest and cheapest to conduct and control. In this study, the sprouts of the wheat (Triticum aestivum L.) varieties Arkadia and Tonacja underwent biofortification with Fe, Zn, Mg, and Cr solutions in hydroponic media at four concentrations (0, 50, 100, and 200 µg g−1) over four and seven days. Moreover, this study is the first to combine sprout biofortification with UV-C (λ = 254 nm) radiation treatment for seed surface sterilization. The results showed that UV-C radiation was effective in suppressing seed germination contamination by microorganisms. The seed germination energy was slightly affected by UV-C radiation but remained at a high level (79–95%). The influence of this non-chemical sterilization process on seeds was tested in an innovative manner using a scanning electron microscope (SEM) and EXAKT thin-section cutting. The applied sterilization process reduced neither the growth and development of sprouts nor nutrient bioassimilation. In general, wheat sprouts easily accumulate Fe, Zn, Mg, and Cr during the applied growth period. A very strong correlation between the ion concentration in the media and microelement assimilation in the plant tissues (R2 > 0.9) was detected. The results of the quantitative ion assays performed with atomic absorption spectrometry (AAS) using the flame atomization method were correlated with the morphological evaluation of sprouts in order to determine the optimum concentration of individual elements in the hydroponic solution. The best conditions were indicated for 7-day cultivation in 100 µg g−1 of solutions with Fe (218% and 322% better nutrient accumulation in comparison to the control condition) and Zn (19 and 29 times richer in zinc concentration compared to the sprouts without supplementation). The maximum plant product biofortification with magnesium did not exceed 40% in intensity compared to the control sample. The best-developed sprouts were grown in the solution with 50 µg g−1 of Cr. In contrast, the concentration of 200 µg g−1 was clearly toxic to the wheat sprouts.

“…After 3 hours at an irradiance of 1.3 mW/cm2, the seed coat thickness of the soft, macha, and red dika kinds of wheat rose by 28%, 25-36%, and 66-77%, respectively. In comparison to the other two wheat varieties, the red dika wheat had the thickest seed coat (Badridze et al 2016). Exposure to UV A enhanced the germination of mung bean (Vigna radiata L.) seeds and improved seedling growth in terms of leaf area, root and shoot length, and dry weight (Hamid and Jawaid 2011).…”

Light is the primary element that plants need to grow, and UV rays, the harmful part of solar radiation, can decrease plant growth by slowing down the metabolic rate of photosynthesis. There are three different types of ultraviolet (UV) radiation, each with a distinct waveband: UV-A (315–400 nm), UV-B (280–315 nm), and UV-C (280 nm). Wavelength, intensity, and exposure to light have a big impact on plant quality and growth. Photoreceptors such as UV Resistance Locus 8 (UVR8), which promotes adaptation to UV-B stress, control how plants interact with UV radiation. While it is well established that UV in large amounts can harm production and quality metrics, some studies suggest that UV in moderate doses may promote biomass growth and the creation of beneficial chemicals that primarily absorb UV. It is well known that UV radiation causes differences in plant architecture, which are significant in ornamental crops and raise their economic value. Increased resistance to insects and diseases and a reduction in postharvest quality depletion are two effects of abiotic stress brought on by UV exposure. This review emphasises how UV may affect plant quality, growth, photomorphogenesis, and resistance to abiotic and biotic stress.

Background. The processes occurring in plants and their seeds under stress, as well as the defense mechanisms used by plants under stress, are poorly understood, which makes it impossible to use them to increase yields. Purpose. Review and analysis of scientific publications, devoted to the phenomenon of stress memory acquired by plants as a result of physical stressors on their seeds and possible applications of this phenomenon in plant growing and crop breeding. Materials and methods. A selection and systematic review of scientific articles on the research topic for the period 2016-2023 was performed. The study consisted of the following steps: research literature search, evaluation and selection, data synthesis and analysis. Results. The use of hormetic effects of physical agents to stimulate seed germination of crops is effective. Responses to abiotic stresses could be 'trained' by priming so that the plant becomes better able to cope with later stress. Evidence of short-term and transgenerational memory formation following plant priming has been obtained. An epigenetic mechanism for the formation of long-term stress memory in plants as a result of a physical eustressor has been identified. The eustressor induces specific epigenetic marks associated with environmental adaptation, forming a new stress-resistant plant phenotype. Physical eustressors have the potential to impart stress tolerance to crops to enhance phenotypic characteristics to prevent yield losses. Conclusion. Seed treatment with physical stressors builds plant tolerance and memory to abiotic stresses, but scientific evidence on this issue is incomplete and sketchy. The understanding and application of stress memory for breeding purposes is currently limited, but it has great potential for the development of new crop varieties.
