Improvement of Technology of Electrical and Magnetic Stimulation of Seeds and Crop Plants

Abstract

Use of a variety of electrotechnics is a technologically-efficient and environmentally-friendly technique that increases the productivity of cultivated plants. Stimulation of green plants and vegetable crops in electric field with the intensity of 5-50 kV/m made it clear that the maximum efficiency is observed in the growth period – an increase of up to 30%, compared to the control. Plants have been subjected to stimulation for 3 hours twice a day (in the morning and in the evening). Analysis of studies on the pre-seeding seed stimulation showed that the exposure to pulsed magnetic field improves the dynamics of germination and plant growth at the early stages of development by an average of 10-20%, and more uniform germination helps to ensure high yields.

Electrical stimulation boosts seed germination, seedling growth, and thermotolerance improvement in maize (Zea mays L.)

“…[1][2][3][4][5][6] Exogenous electrical stimulation is an efficient and environmentally friendly technique, which regulates plant growth and development by modifying cellular metabolism via interaction with hydraulic, chemical (Ca 2+ , ROS), and hormone signaling (ABA and JA) in plants. [1][2][3][4]7 In many plant species (Triticum aestivum, Solanum lycopersicum, Raphanus sativus, and Hordeum vulgare, Avena sativa, and Hordeum vulgare), the positive and negative effects of electrical stimulation on seed germination, crop yield, and fruit quality have been observed. [1][2][3][4]8 In addition, more interestingly, electrical stimulation also can improve plant tolerance to salt and freezing stress in wheat and Cucurbita pepo, respectively.…”
