ملخص المقالة :
استرس‌های غیرزیستی از جمله خشکی باعث تحریک ساخته شدن گونه‌های اکسیژن فعال در بافت‌های گیاهی می‌شوند. سیگنالهای ROS شبکه پیچیده‌ای از آنزیم‌های آنتی اکسیدانی را راه اندازی می‌کنند. آسکوربیک اسید یکی از مهمترین بافرهایی است که ساختارهای سلولی را در مقابل حمله اکسیدانها در گیاهان حفظ می‌نماید. اثرات تنش خشکی در دو حالت حضور و عدم حضور آسکوربات خارجی بر فعالیت آنزیم‌های کاتالاز(CAT)، آسکوربات پراکسیداز (APX) و پلی فنل اکسیداز (PPO) در گیاه علفی و معطر Pimpinella anisum L. با ارزش صادراتی فراوان که در معرض کمبود آب کنترل شده قرار گرفته بود، مورد مطالعه قرار گرفت. با توجه به اهمیت این گونه گیاهی، این آزمایش در شرایط گلدانی انجام شد و سنجشهای بیوشیمیایی و فیزیولوژیکی به صورت تصادفی در شاهد و تیمارها (با دو عامل خشکی 60درصد و 25در صد ظرفیت زراعی خاک و یک عامل آسکوربات با غلظت mM 4/1 صورت پذیرفت. نتایج حاصل نشان داد فعالیت آنزیم‌های PPO, APX, CAT در حضور و غیاب آسکوربات با پیشرفت تنش در برگها بطور معنی‌داری نسبت به شاهد افزایش یافت. در ریشه فعالیت آنزیم‌های CAT و APX در غیاب آسکوربات ابتدا در سطح خشکی 60در صد ظرفیت زراعی افزایش معنی‌داری نسبت به شاهد داشت و سپس در سطح درصد 25 ظرفیت زراعی با کاهشی در حد شاهد روبرو شد که با اعمال آسکوربات خارجی فعالیت آنزیم‌های ریشه ای تا حد معنی‌داری تقریبا در تمام سطوح افزایش یافت.
