چکیده مقاله :
در استرس‌های مختلف از جمله استرس شوری،اکسیدان‌های قوی نظیر گونه‌های اکسیژن فعال تولید می‌شود که به ساختار غشاء در گیاه آسیب می‌رساند. در بین آنتی اکسیدان ها، آسکوربات دارای نقش حیاتی در سلول‌های زنده بوده و سبب از بین رفتن گونه‌های اکسیژن فعال می‌شود.در این تحقیق دانه رست‌های سویا رقم DPX تحت تاثیر غلظت‌های مختلف آسکوربات (1و2میلی مول) و نمک (50 میلی‌مول) قرار گرفت واثر آنها بر روی درصد جوانه زنی، طول ریشه چه و فعالیت آنزیمهای آنتی اکسیدانی نظیر کاتالاز،پلی فنل اکسیداز،آسکوربات پراکسیداز و پراکسیداز ارزیابی شد.نتایج حاصل از این تحقیق نشان داد که در فقدان آسکوربات و در حضور نمک میزان فعالیت آنزیمهای آنتی اکسیدان افزایش یافته و لیکن با افزودن آسکوربات میزان فعالیت آنها کاهش یافت. همچنین در صد جوانه‌زنی در حضور نمک کاهش، ولیکن در حضور نمک و آسکوربات در صد جوانه‌زنی افزایش معنی داری حاصل کرد.
In different stress such as salinity, strong oxidant as Reactive Oxygen Species is produced that damages to membrane structure in plant. Different antioxidant as ascorbate scavenger them. In this research Soybean (Glycine max L. cv DPX) in different concentrations of ascorbate (1,2mM) and NaCl (50mM) and the effect of them on germination percentage, radicle length and antioxidant enzymes such as catalase, peroxidase, polyphenol oxidase and ascorbate peroxidase was evaluated. The results of this research showed that in absence of ascorbate and present of NaCl activity of enzymes increased but with increasing of ascorbate, activity of them decreased. Also in present of NaCl germination decreased but in NaCl and ascorbate germination increased significantly.
