Abstract :
Electromagnetic fields is one of the effective factors on the living organisms, and therefore in thepresent study the effects of different treatments of electromagnetic fields on the growth indices ,antioxidant activity and vegetative and sexual structures of Pumpkin were assayed. Seed samples ofpumpkin were treated by 2 mT of electromagnetic fields , in 15 and 30 mins, in to different groupsnamed dry and wet. Microtomic and manual sectioning were used to study the vegetative and sexualstructures. The results showed that the treatment affected some indices in the negative or somehowpositive way. The array of xylem in leave section and trichomes structure were also changed. Thesize of trichomes were significantly increased . In 30 min wet treatment the xylem was more hugeand the number of vessels increased. There was no remarkable difference between the treatments andcontrol sample in vegetative meristems of stem and root in microtomy section. But generativemeristems were more massive and more cheeky. There was no difference between the treatments andcontrol sample in anther wall either, except a change in 30 minute wet treatment which was theincrease of the number of transition layer cells. The most changes were in 30 minute wet treatments.In those treatments ovum and stew tissue were injured and the embryo sac was abnormal. Also therewas a gap between cortex and stew tissue.
