Abstract
Electromagnetic fields is one of the effective factors on the living organisms and therefore in the present study the effects of different treatments of electromagnetic fields on the growth indices, chromosomal state and pollen structures of pumpkin were assayed. Seed samples of pumpkin were treated by 2 mT of electromagnetic fields in 15 and 30 min, in two different groups named dry and wet. The results showed that the treatment affected some indices in the negative or somehow positive way. The root length and germination percentage however were not affected significantly. The hypocotyl length of 15 min treatment was decreased in comparison with control samples. The shoot length of wet treated samples was significantly reduced compare to controls. Caryologic studies showed that the most important effect of electromagnetic fields, belongs to chromosomal aberrations so that some mitotic phase such as metaphase and anaphase were delayed. SEM microscoping assay showed that more electromagnetic fields causes disorder of pollen surface.
