The effect of magnetic field applications on seed attributes of Anatolian crimean pine (Pinus nigra Arn. subsp. pallasiana (Lam.) Holmboe) and scotch pine (Pinus sylvestris L.)

In this study, the effects of electromagnetic field applications on Anatolian Crimean pine (Pinus nigra Arn. subsp. pallasiana (Lamb.) Holmboe) and Scotch pine (Pinus sylvestris L.) were investigated. The seeds were exposed to different treatment period 5 min, 10 min and 15 min and varied magnetic field intensities 150 mT, 300 mT and 450 mT, respectively. The control and experimental groups were germinated at equal conditions. Seeds responses were recorded in 4th, 7th, 14th, 21th and 27th days, and the percentage and germination speed of seeds were determined. The data obtained from the percentage and germination speed of seeds with the different magnetic field intensities and treatment period variance analysis was performed with SPSS statistical software. As a result, the germination percentages and rates in Scotch pine and Crimean pinewere higher determined in the magnetic field applications than that in the control group. Duncan test to determine the most appropriate procedures have been applied. According this, generally, the best germination rate and percentage in magnetic field intensity which was applied for 450 mT and 5 min was obtained.
