This paper presents a discussion about the application of electricity that stimulates the growth of the plant to a great extent. This paper also demonstrates that exposure to the action of a high voltage electric field can be an effective tool for the enhancement of germination. The experiments were carried out on tomato seeds. A pilot treatment unit was developed and used for the study. Under normal conditions (no treatment), only about 76% of a reference sample of such seeds were germinated. Other seed samples were subjected to 50 Hz electric fields ranging from 10 to 30 kV cm-1 with exposure time ranging from 10 to 30 sec. In the optimum laboratory test, 100% of the seeds were germinated. The weight of the resulting tomato seedlings was greater than that of untreated ones. The germination tests proved the efficiency of this method. Ozone generation by partial discharges between seeds seems to be the main effective parameter that enhances the growth.

This study was conducted to determine the influence of high-voltage electrical stimulation on quality of cooked beef hams produced from semitendinosus muscle of heifers and young bulls. Texture evaluation of hams was conducted with the universal testing machine Instron type 4301. Additionally, puncture and shear tests were performed. Six trained panelists conducted sensory analysis. The attributes evaluated were as follow: appearance, structure and consistency, taste and flavour as well as tenderness. The results of sensory examination and instrumental measurement revealed that the influence of high-voltage electrical stimulation on cooked hams depends on animals sex. The most significant difference in quality of hams was observed between stimulated and non-stimulated hams produced from semitendinosus muscle of heifers.
