Effect of treatment of seeds of grain crops by ultraviolet radiation before sowing

Abstract

Cereals form the most important group of plants cultivated by man. The aim of the work is to study the effect of ultraviolet led emitter in the processing of seeds of grain crops to improve sowing performance. The objects of the study were the seeds of winter and spring wheat, winter triticale, naked oats. Seeds were treated with ultraviolet LEDs in the range of radiation in the UV zone for 5, 10 and 15 minutes, with average illumination energy of 3.137 W/m2. Growth strength, laboratory germination, shoot height, primary root length and root rot infestation were evaluated. In the course of studies, a positive effect of ultraviolet treatment of seeds of winter wheat, winter triticale and oats was established. Ultraviolet radiation with a dose of 1882 J/m2 (seed treatment for 10 minutes) increased the growth strength and germination of winter wheat. Shoot height and root length were better when irradiated for 5 min with a dose of 941 J/m2. The proposed UV treatment of seeds improves the technology of production of hydroponic feed, taking into account modern requirements for energy conservation and obtaining environmentally friendly products.

Surface disinfection of wheat kernels using gas phase hydroxyl‐radical processes: Effect on germination characteristics, microbial load, and functional properties

“…According to Kondrateva et al. (2020), exposure to UV radiation had a positive impact on wheat germination. The authors reported that a 10 min exposure to UV with a dose of 188.2 mJ/cm 2 led to an increase in the growth strength and germination rate of tested winter wheat.…”

“…The authors reported that a 10 min exposure to UV with a dose of 188.2 mJ/cm 2 led to an increase in the growth strength and germination rate of tested winter wheat. However, their study employed primarily UV‐A radiation that has less lethality compared to UV‐C (Kondrateva et al., 2020). In another investigation, it was observed that exposing corn kernels to UV‐C radiation (254 nm) with a dose of 5000 mJ/cm 2 did not have a negative effect on the kernels’ ability to germinate (Popović et al., 2018).…”

Treatment of animals without antibiotics

“…The technique of direct electrochemical oxidation of blood has been developed, which does not require the use of antibiotics in the treatment of animals. For the first time [8,9,10] the process of electrochemical oxidation of blood inside a blood vessel was performed. The chlorine ion, which is part of the sodium chloride in the blood plasma, is oxidized.…”

The effect of synergism in seed treatment with electron-donor solution and UV irradiation

“…There are many ways to remove seeds from a dormant state. In the literature [5], seed germination is activated with the help of environmentally safe and inexpensive ultraviolet radiation. Song L., Wang Q., and other scientists [6] investigated the effect of g-irradiation on the germination energy of rice seeds, estimated using infrared spectroscopy.…”

“…Kondrateva N. P., Kasatkina N. I., Kuryleva A [9] showed a positive effect of ultraviolet irradiation on the awakening of grain seeds. Kondrateva N., Rudenok V., Kasatkina N. [13] obtained a synergistic effect from simultaneous exposure to ultraviolet radiation and a nanosilicon preparation to increase the germination rate of seeds. Therefore, the search for new methods of pre-planting seed treatment, ensuring an increase in their yield, is an urgent task.…”
