Influence of spring wheat seed treatment with low-temperature plasma on growth processes

Abstract

In the Russian Federation in recent years, fallow lands have been actively put into circulation. On fallow lands a complex of agromeliorative measures is carried out. The demand for high quality seeds for sowing in the newly introduced into turnover lands is also increasing. The purpose of our research is to study the influence of corona discharge of low-temperature plasma on seeds and growth processes of spring wheat. The research was conducted on the basis of the Institute of Artificial Intelligence, Robotics and Systems Engineering KFU To conduct experiments in the laboratory of the Department of Biomedical Engineering and Artificial Intelligence in Biotechnical Systems of the Institute of Artificial Intelligence and Systems Engineering KFU in 2022–2024 developed a scheme and assembled the installation of corona discharge generation of low-temperature atmospheric plasma. The experiments were carried out in tenfold repetition. Seeds were treated with corona discharge at the following parameters: voltage 4 and 8 kV; frequency 0.2 kHz; 0.3 kHz; 0.5 kHz; seed distance from the plasmatron 3 cm; seed treatment time: 20, 25, 30, 35 seconds. Seeds of control variant and variants with corona atmospheric plasma treatment were germinated by roll method in Lamsystem laminar flow cabinet. The data obtained show that at a voltage of 4 kV, the highest growth of wheat seedlings was observed at a frequency of 0.5 kHz and a treatment time of 30 seconds. The length of seedlings for seven days, on this variant of seeds treated with corona discharge on average reaches up to 34.4 cm, and the length on the control variant of the experiment 11.7 cm, which is 22.7 cm shorter. The greatest length of seedlings at a voltage of 8 kV is observed at a treatment time of 30 seconds, where the length of the seedling reaches 36.2 cm, which is 24.5 cm more from the control variant of the experiment.
