The influence of low frequency electromagnetic field on the growth indicators of wheat seedlings

The aim of the study was to analyze the influence of the low frequency electromagnetic field of the power transmission line with an electric voltage of 500 kV on the growth indicators of seedlings. As the object of the research the soft spring-sown wheat of the variety Krasnoyarskaya 12 served. Field experiments were made near the settlement of Drokino of the Emelyanovo area of Krasnoyarsk Region within July-August, 2019. The frequency in each option was 4-fold. The experiments were repeated 3 times. Statistical processing of the obtained data was carried out by the standard methods by means of the standard computer Microsoft Excel programs. The reliability of the results was estimated, using Student's t-criterion at p ≤ 0.05. Variety wheat seeds Krasnoyarskaya 12 displayed on 50 pieces in Petri's dishes to which 10 ml of water were added. In field experiments the wetted seeds placed directly under the power line-500 (experiment) and at the distance about 100 m from it (control). At the age of 7 days the share of sprouted seeds was counted, the length of the 1-st leaf, fresh mass of elevated part and roots were measured. The distribution of the seedlings on the length of the 1-st leaf in each option of experiment was calculated. According to the executed measurements, the size of magnetic induction under the power line-500 made about 50 MGs and decreased almost to zero at the distance from it more than 70 m. The influence of electromagnetic field having such value of magnetic induction on the viability of seeds, the size of elevated part of biomass and roots, the length of the 1-st leaf of seedlings has not been statistically proven. At the same time, under the influence of electromagnetic field, there was a tendency to reduce the proportion of seedlings with sizes above average. At the early stages of wheat development, the low-frequency electromagnetic field created by the power line-500 is not supposed to be significant negative factor for the plants.
