چکیده مقاله :
رقم‌های مختلف از یک گونه، آنزیم‌های مختلفی را به منظور مقابله با تنش فعال می نمایند که شامل سوپراکسید دیسموتاز، کاتالاز، پراکسیداز، گلوتاتیون ردوکتاز، آسکوربات پراکسیداز بوده و نقش مهمی را در دفاع از گیاهان در برابر انواع اکسیژن واکنشگربازی می‌کنند. هدف از این پژوهش، مطالعه تفاوت رفتاری آنزیم‌های پراکسیداز، کاتالاز وآسکوربات پراکسیداز در دو رقم سویا شامل پرشینگ و DPX در برابر تنش خشکی و غرقابی وبررسی اثر تنش‌های مختلف آبی بر روی میزان فعالیت آنزیم‌های مذکور بود. درنتیجه آزمایشی در شرایط گلدانی انجام گرفت و تیمارهای آبی20، 40، 60 و80 درصد ظرفیت اشباع آب خاک بر روی آنها اعمال گردید. فعالیت آنزیم‌های آنتی اکسیدانی تفاوتهایی را از نظر نوع تنش و نوع اندام نشان دادند، به نحوی که فعالیت آنزیم پراکسیداز در ریشه و گرهک تحت دو تنش غرقابی و خشکی افزایش یافت، اما در برگ فعالیت آنزیم تحت تنش خشکی و غرقابی تفاوت معنی‌داری را نشان نداد و تنها در رقم پرشینگ، فعالیت آنزیم در تنش خشکی افزایش معنی‌داری را نشان داد. فعالیت آنزیم کاتالاز در دو اندام برگ و ریشه در رقم DPX در تنش غرقابی و در رقم پرشینگ در تنش خشکی افزایش یافت و در سایر تیمارها تفاوت معنی‌داری مشاهده نشد. فعالیت آنزیم آسکوربات پراکسیداز در برگ به ازاء کاهش میزان آبیاری کاهش یافت، اما در ریشه فعالیت آنزیم نامبرده در رقم DPX تحت تنش غرقابی و در رقم پرشینگ تحت تنش خشکی افزایش معنی‌داری را نشان داد. نتایج مطالعات مشخص نمود که فعالیت آنزیم می تواند با توجه به نوع رقم، نوع تنش وحتی نوع اندام
Different cultivars of one species activate various enzymes such as superoxide dismutase, catalase, peroxidase, glutathione reductase and ascorbate peroxidase in order to defense against the water stress.These enzymes have important role in plant defense against the reactive oxygene species. In this study, behavior different of peroxidase, ascorbate peroxidase and catalase and effects of water stress on activity of them against drought and flooding were investigated in two soybean cultivars (Glycine max L. cv. Pershing and cv. DPX). An experiment was carried out under potting conditions and 4 treatments (20, 40, 60 and 80% of water saturation capacity) were used. Antioxidant enzymes indicated differences with stress and organ. Peroxidase activity increased in nodule and root under drought and flooding stress but in leaf, peroxidase activity increased in lower water contents (20 and 40%) and in DPX, significant difference did not shown in the all. In both studied organs, catalase activity increased in flooding and drought, in DPX and Pershing, repectively but significant difference did not shown in other treatment. In the leaf, ascorbate peroxidase activity decreased with decreasing in irrigation but in root, its activity indicated significant increaseing in flooding and drought, in DPX and Pershing, repectively. Results indicated that enzymetic activity can vary by cultivar, stress and organ type, too.
