“…LEEB application to lentil seeds accelerated seed germination, defined by the percentage of hypocotyl and leaf emergence at 3 days [99]. There are also reports that low doses of this type of radiation, applied to barley seeds, induced higher germination rates [100] while it improved the height and weight in wheat plants [101].…”

The study of the effect of low doses of ionizing radiation on the germination and initial growth of different seeds is a recent area of research, with gamma rays and X-rays receiving the most attention. The use of this type of energy can generate an increase in germination percentages, an increase in germination speed, and changes in the length and area of roots and shoots, which will depend both on intrinsic factors of the nature of the energy (dose, dose rate, energy, etc.) as well as aspects of the irradiated seeds (water content, sensitivity, etc.). In addition to morphological effects, radio-stimulation due to low doses of ionizing radiation (a phenomenon also described as radio-hormesis) generates changes at physiological, biochemical, metabolic, and molecular levels. Despite the evidence that has been accumulating, it is still necessary to deepen the knowledge about these phenomena in order to establish the use of ionizing radiation with the aim of using radio-stimulation as a real impact tool in the agroforestry sector.

“…In the past few years, it has not only been used to sterilize the microbial contamination and combat the pathogenic on plants to prevent pre-harvest produce contamination, but it also has potentially accelerated the plants’ growth at low doses [ 50 , 51 , 79 , 80 , 81 ]. For example, researchers found that electron radiation positively affected the seed growth in barley ( Hordeum vulgare L.), and after a series of doses, the 5 kGy maximal one induced the increase in the cell length and the cell width of the coleoptile [ 49 ]. The stimulatory effects of low levels of electron beam (15 kGy, 100 keV) radiation have also been reported by Doroshkevich, and according to their research, the irradiation stimulated various aspects of the plants’ development such as the germination rate, the germination capacity, and the height and weight of Triticum aestivum L. [ 48 ].…”

To overcome various factors that limit crop production and to meet the growing demand for food by the increasing world population. Seed priming technology has been proposed, and it is considered to be a promising strategy for agricultural sciences and food technology. This technology helps to curtail the germination time, increase the seed vigor, improve the seedling establishment, and enhance the stress tolerance, all of which are conducive to improving the crop yield. Meanwhile, it can be used to reduce seed infection for better physiological or phytosanitary quality. Compared to conventional methods, such as the use of water or chemical-based agents, X-rays, gamma rays, electron beams, proton beams, and heavy ion beams have emerged as promising physics strategies for seed priming as they are time-saving, more effective, environmentally friendly, and there is a greater certainty for yield improvement. Ionizing radiation (IR) has certain biological advantages over other seed priming methods since it generates charged ions while penetrating through the target organisms, and it has enough energy to cause biological effects. However, before the wide utilization of ionizing priming methods in agriculture, extensive research is needed to explore their effects on seed priming and to focus on the underlying mechanism of them. Overall, this review aims to highlight the current understanding of ionizing priming methods and their applicability for promoting agroecological resilience and meeting the challenges of food crises nowadays.
