“…Maghrabi and Zaheer [12] showed that low doses (5 and 10 krad) of c-irradiation can alleviate the adverse effect of salinity stress in two barley plants C.V. Aasla and Giza 124, whereas higher doses (15 krad and 20 krad) alone or combined with salt (5000-10 000 ppm NaCl) induced reduction in the germination, shoot and root length, fresh and dry weights and chlorophyll a, b and carotenoids. Cholakov et al [13] found that the yield increased when seeds of cucumber cultivar Pobeda F were irradiated with a heliumneon laser at 632.8 nm and an output power of 20 mW and/or with c-rays from radioactive cobalt ( 60 Co). Accordingly, it was felt worthwhile to investigate the stimulatory effects of c-irradiation on corn grains in the biophysical properties of chlorophyll in corn cultivar making use of both fluorescence and The effects of c-irradiation on the biophysical and morphological properties of corn plants were investigated.…”

The effects of gamma-irradiation on the biophysical and morphological properties of corn plants were investigated. The irradiation doses were 0, 1, 1.5, 2.5, 5, and 10 krad. Corn grains exposed to 1.5 and 2.5 krad showed highly significant changes in all growth parameters. Fluorescence and light absorption spectra of chlorophyll attributed to different doses treatments of corn grains clearly confirmed the superiority of 1.5 krad irradiation dose in stimulating corn plants. Furthermore, the frequency dependence of the relative permittivity and the electric conductivity of the treated samples have been performed and discussed. The obtained results give another support via the biophysical properties for the 1.5 krad irradiation dose to be the most favorable one to improve the plant growth characteristics.

We review the literature concerning the effects of laser light on organisms (insects) and microorganisms (bacteria, viruses, fungi) present in agri-food systems. The evidence obtained shows that 1) Laser light is a sustainable technology that can be applied as a pesticide with the ability to annihilate and control insects. Higher annihilation rates are observed for more pigmented products, as determined by their thermal and optical properties. 2) The most frequently used laser beams to eliminate bacteria harmful to human health operate with a steady intensity in the visible domain (blue, green, and red light). 3) Laser beams are applied to control fungi (the most studied microorganism), viruses, as well as to increase plant resistance to them. Lasers with red beams, such as those emitted by He-Ne lasers, followed by diode lasers are most frequently reported in fungal control. Furthermore, antibacterial, and germicidal effects are increased by using photosensitizers. Finally, 4) laser light potentiates the metabolites and antimicrobial activity of some plants thereby improving their activity. Agri-food systems treated with laser beams have the potential to improve the quality of life of society.K e y w o r d s: laser technology, sustainable technology, antibacterial, antifungal, pesticidal
