| چکیده | ||
| به منظور بررسی اثر پلاسمای سرد بر شاخصههای جوانهزنی بذر کاملینا و رفع خواب بذور کرفس کوهی و گلپر، آزمایشی در قالب طرح کاملا تصادفی با 3 تیمار و 3 تکرار انجام شد. تیمارها شامل 3 توان 40، 60 و 80 وات پلاسمای سرد بودند که به مدت 2 دقیقه بر روی بذور اعمال شدند و نمونه تیمار نشده نیز به عنوان تیمار شاهد مورد ارزیابی قرار گرفت. صفات مورد مطالعه عبارت بودند از: درصد جوانهزنی، سرعت جوانهزنی، طول ریشهچه و طول ساقهچه. نتایج نشان داد که تیمار پلاسمای سرد سبب افزایش معنیدار درصد جوانهزنی، سرعت جوانهزنی، و طول ریشهچه در مقایسه با تیمار شاهد گردید ولی نتوانست خواب بذور کرفس کوهی و گلپر را برطرف نماید. در رابطه با بذر کاملینا، تیمار پلاسمای سرد 80 وات سبب بهبود درصد جوانهزنی به میزان 6/10 درصد، سرعت جوانهزنی به میزان 35/2 بذر در روز و طول ریشهچه برابر با 6/3 سانتیمتر گردید، که افزایش قابل توجهی نسبت به شاهد و سایر تیمارها داشت. بر اساس نتایج به دست آمده برای بذور کرفس کوهی و گلپر، به رغم بهبود آبدوستی و ضد عفونی شدن بذور، پلاسمای سرد در شکستن خواب این بذور اثری نداشت. | ||

| In this research, the effect of cold plasma treatment on the germination characteristics of Camelina sativa, Kelussia odoratissima, and Heracleum persicum seeds were investigated. An experiment based on completely randomized design with in three replications was conducted. The treatments were three cold plasma power of 40, 60 and 80 W applied on the seeds for 2 minutes and untreated sample was also evaluated as control treatment. The measured traits were: germination percentage and rate, plumule and radicle length. The results showed that cold plasma treatment had a significant effect on germination percentage, germination rate, and radicle length. The cold plasma at 80 kV and 2 minutes improved the germination percentage with increasing it by 10.6%, increasing germination rate by 2.35%, and 3.6 centimeters in radicle length in compared with the control sample. Based on the results obtained from K. odoratissima and H. persicum seeds, cold plasma couldn’t break the dormancy of these seeds, despite the improved hydrophilicity and disinfection of the seeds. | ||
