RADIATION EFFECTS AND DEFECTS IN SOLIDS, cilt.180, sa.9-10, ss.1-18, 2025 (Hakemli Dergi)
All biological systems are affected by radiation and magnetic fields
(MFs). This study investigated the effects of gamma radiation and
magnetic field treatments, both separately and together, on the
seedling percentage, length, and chlorophyll content in the M1(first
generation of plants) generation of Defiance, General, and Iraquois
soybean cultivars. A magnetic field (MF) with a flux density of 3.8-
4.8 mT was applied to the seeds of three soybean cultivars at a
speed of 1 m/s for 2.2 s (1 time MF), 6.6 s (3 times MF), and 19.8 s
(9 times MF). Additionally, 200 and 250 Gy gamma radiation were
applied combined with a magnetic field (200, 250 Gy+MF). The
treated seeds were grown in a greenhouse under controlled conditions,
and each treatment was repeated three times using a randomised
block design. On the 14th day, the seedling emergence
percentage, seedling height, and chlorophyll content of seedlings
were determined. ANOVA, Tukey, and Kruskal–Wallis tests were used
for statistical analysis of the obtained data. The results showed that
magnetic fields positively affected germination in Defiance and General;
radiation generally reduced growth, but the combination of
treatments affected seedling growth and chlorophyll content, with
effects varying depending on dose and variety.
