Rezultate biometrice ale plantelor de grâu, tomate și busuioc în rezultatul iradierii cu unde GSM și 3G

Abstract

The impetuous development of modern communication technologies as well as the increase of the life rhythm generated the enhancement of communication needs and connections to data services at high speeds. These led to a corresponding increase of the energy consumed and respectively released into the ether. It should be borne in mind that usually the speeding up of wireless communication is done by moving to higher frequencies, which leads to the increase of energy emitted in the corresponding frequency domain in order to cover required area. The purpose of this study is to study the influence of some radiation in the GSM and 3G frequencies on the germination and growth of wheat grains and tomato seeds. These frequencies were selected following previous observations as the most intense in the urban area. As trial samples, wheat cultures (Triticum aestivum L., Dropia spp.), cherry tomatoes (Lycopersicum esculentum) and basil (Ocimum basilicum) were selected, the radiation being produced and controlled by two radio frequency amplifiers for the 3G (UL1920-1990, DL2110-2180) and GSM (UL880-915, DL925-960). For wheat, there was a variation of the germination rate in the range of 62% to 79.3%, depending on the applied radiation. For tomatoes, the germination rate vary from 56% to 62.6%. For basil, the germination rate vary from 57% to 62%. As control samples, the plantlets were grown in a Faraday cage and under normal laboratory conditions. The germination rate at the 14th day, the length of the stem and root of the plantlets, as well as the number of plantlets for which the first leaves appeared were studied.
