Abstract

Previous studies have shown that magnetic fields can increase seed vigor, growth, and tomato plant production. This study aims to examine the effect of 0.2 mT magnetic field exposure duration on the generative growth of tomatoes from old seeds. The study was conducted from January to April 2019 at the Botany Laboratory, Department of Biology, Faculty of Mathematics and Natural Sciences, and at the Integrated Field Laboratory, Faculty of Agriculture, University of Lampung. The study was conducted using a completely randomized design (CRD) one factor with 5 levels of treatment, namely positive control (SnM0) is a new seed without magnetic field exposure, negative control (SoM0) is an old seed without magnetic field exposure, an old seed with a long exposure period of 7 minutes 48 seconds (SoM7), 11 minutes 44 seconds (SoM11), 15 minutes 36 seconds (SoM15). Each treatment unit was repeated five times. The generative growth parameters measured were carbohydrate content, number of flowers, speed of fruit formation, number of fruits and number of seeds per fruit. The data obtained were analyzed by variance followed by Fisher's test at α = 5% to see the smallest difference between treatments. The results obtained indicate that the magnetic field of 0.2 mT can increase the generative growth of tomato plants from old seeds. Exposure to a magnetic field of 0.2 mT for 7 minutes 48 seconds gives the best results on parameters of carbohydrate content, speed of fruit formation, number of flowers, and number of small fruit seeds, 11 minutes 44 seconds on the number of flowers and number of fruits, 15 minutes 36 seconds large number of fruit seeds. Keywords: Old Seeds, Lycopersicum esculentum Mill., Magnetic Field, and Generative Growth.
