effect of magnetic field and its stability on growth indices of parsley (petroselinum crispum) seeds

Recent research has proven that magnetic field application enhanced the percentage of germinated seed and shortened the period of seed germination. in present research in order to evaluation of the effect of magnetic field on seed germination and seedling growth indices of smooth leaf type parsley seeds and also the stability of magnetic properties on this seed, the quadrupole magnetic field was used. the experiment was conducted as factorial in a completely randomized design with three replications. factors include; magnetic field intensity (150, 300 and 450 mt), time exposure (30, 60 and 90 min) and culture time (0, 7 and 14 days after the magnetic field application). the results of anova showed the magnetic field had a significant effect on shoot length, fresh root weight and dry shoot weight (p≤0.01) and on fresh shoot weight (p≤0.05). duration of the field application (time exposure), significantly affected on root length (p≤0.01). culture time had a significant effect on root length, fresh root weight and dry shoot weight (p≤0.01) and also had a significant effect on other factors (p≤0.05). culture time without delay after applying magnetic field (0 day) increased the root length and culture time at the 14 days after applying magnetic field increased the shoot length, fresh weight of root, fresh shoot weight, dry root weight and dry root weight. our results suggest that magnetic field and culture time treatments can be used as a physical technique to improve the most of seedling growth indices of parsley seeds.
