RESEARCH OF EFFECT OF LOW FREQUENCY MAGNETIC FIELD ON GERMINATION, GROWTH AND FRUITING OF FIELD TOMATOES

摘要

In the study regarding with tomatoes, the impact of extremely low frequency electromagnetic fields on seed germination of tomato (Solarium lycopersicum L.) after treatment before sowing, as well as the growth following electromagnetic stimulation of young plants at a time before planting in the field, and fruittraits was investigated. In the experiments conducted in two consecutive years (2012 and 2013), we followed the time of seed germination of tomato variety "Pavlina", plant growth and the fruitsize. Magnetization of seeds and young plants was carried out in laboratory conditions, and plant growth and fruits were followed in field conditions where plants were grown on experimental plots (25.0 m2).The plants were grown in accordance with the standards of agricultural practice for tomato. At the generative phase, fruits were collected at regular intervals, and their number and weight were evaluated. Low frequency electromagnetic fields acting at the three inductance levels (20, 40 and 60 mT) andexposure of 20 minutes a day with frequency of 50 Hz, significantly influenced the germination, plant growth and fruitsize of the studied tomato variety.
