چکیده مقاله :
تنش شوری یکی از مهمترین تنشهای محیطی است که سبب کاهش رشد و عملکرد گیاهان در سراسر دنیا میشود. در این آزمایش اثر اسید هیومیک بر رشد و برخی پاسخهای فیزیولوژیکی گیاه گندم تحت تنش شوری در یک آزمایش گلدانی مورد ارزیابی قرارگرفت. آزمایش بهصورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با سطوح شوری و اسید هیومیک بهعنوان فاکتورهای اصلی در سال 1395-1396 در دانشگاه ایلام انجام گرفت. تیمارها شامل چهار سطح تنش شوری شامل بدون تنش شوری (آبیاری با آب مقطر) و 4، 8 و 12 دسی زیمنس بر متر NaCl و چهار غلظت اسید هیومیک شامل صفر (بهعنوان شاهد)، 50، 100 و 150 میلیگرم در لیتر بودند. نتایج تجزیه واریانس دادهها نشان داد که اسید هیومیک تأثیر معنیداری بر صفات مورفولوژیکی و فیزیولوژیکی گندم تحت تنش شوری داشت. تنش شوری تأثیر منفی بر رشد و عملکرد گیاه گذاشت. در شرایط تنش شوری، پارامترهای رشد و اجزای عملکرد، محتوای کلروفیل و رطوبت نسبی کاهش ولی فعالیت آنزیمهای آنتیاکسیدان کاتالاز، پر اکسیداز و همچنین نشت یونی افزایش یافت. کاربرد اسید هیومیک سبب افزایش معنیدار پارامترهای رشد، عملکرد، کلروفیل، فعالیت آنزیمهای کاتالاز، پراکسیداز و کاهش معنیدار نشت یونی شد. با افزایش غلظت اسید هیومیک، اثربخشی آن افزایش یافت بهطوری که بالاترین تأثیر در غلظت 150 میلیگرم در لیتر مشاهده شد. بهطور کلی نتایج نشان داد که کاربرد هیومیک اسید با تأثیر بر فرآیندهای فیزیولوژیکی گیاه تا حدی میتواند آثار شوری بر گندم را کاهش دهد.
Salinity is a major environmental stress, reducing growth and yield of a wide variety of crops all over the world. The present study assessed effects of humic acid and salinity stress on the growth and some physiological responses of wheat in a pot experiment. The layout was 4×4 factorial experiment in RCBD design with salinity stress levels and humic acid concentrations as main factors in Ilam University during 2016. Treatments were the combination of four levels of salinity stress including stress-free conditions (irrigation by distilled water), and 4, 8, and 12 dS/m NaCl and four concentrations of humic acid including 0 (as a control), 50, 100, and 150 mg/l. The statistical analysis showed that salinity stress and humic acid application had significance effects on the morphological, physiological, and biochemical parameters of the wheat plants. Salinity stress imposed negative effects on plant growth and productivity. Under salinity conditions, growth parameters and yield attribute, relative water content, and chlorophyll reduced, but electrolyte leakage and antioxidant enzyme activity increased. Application of humic acid significantly increased plant growth parameters, chlorophyll content, and antioxidant enzyme activity, and decreased electrolyte leakage content. The highest salinity tolerance was obtained with 150 mg/l humic acid application. In general, results showed that the application of humic acid through affecting physiological parameters decreased adverse effects of salinity stress on the wheat plants.
