ملخص المقالة :
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.
