چکیده مقاله :
از آنجایی که میدان های الکترومغناطیسی جزء عوامل تاثیر گذار بر روی جانداران به حساب می آیند، از این رو در پژوهش حاضر اثر تیمار های مختلف میدان های الکترومغناطیسی را بر روی ساختار های رویشی و زایشی مورد بررسی قرار داده ایم. نمونه بذر های گیاه کدو تحت تیمار 2 میلی تسلا از میدان الکترومغناطیسی، با مدت زمان 15 و 30 دقیقه و در دو گروه تر و خشک قرار گرفتند. برای بررسی ساختار های رویشی و زایشی از برش گیری های دستی و میکروتومی استفاده شد. نتایج بررسی ها بر روی ساختار های رویشی و زایشی نشانگر تاثیر تیمار میدان های الکترومغناطیسی بر این ساختار ها بوده است. به طوریکه ارایش دسته های آوندی ( بخصوص زایلم) به طور چشمگیری در رگبرگ برگ ها و دمبرگ ها دستخوش تغییر شده و در مواردی کرک ها تحلیل رفته و یا بالعکس بزرگ شده اند. به عنوان مثال در رگبرگ های نمونه تیمار 15 دقیقه خشک نیز شمار دستجات آوندی کم شده و کرک ها به وضوح کشیده تر شده است. در نمونه تیمار30 دقیقه خشک نیز همین وضعیت یعنی کاهش تعداد دسته های آوندی مشاهده شده است. در عین حال باز هم اندازه کرک ها به طور چشمگیری بزرگ تر شده است. در نمونه تیمار 30 دقیقه تر ، همراه با کاهش شمار دسته های آوندی ، شاهد بزرگتر شدن منطقه ی آوندهای چوب و نیز فراختر شدن دهانه آنها می باشیم. در اینجا نیز اندازه کرک ها به وضوح بزرگتر شده است.
چکیده انگلیسی:
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.
