چکیده

سابقه و هدف: تنش شوری یکی از مهم‌ترین چالش‌های محیطی است که به ویژه در مناطق خشک و نیمه‌خشک جهان به‌طور فزاینده‌ای احساس می‌شود. گیاهان مختلف نسبت به شوری واکنش‌های متفاوتی نشان می‌دهند و درک این واکنش‌ها می‌تواند به بهبود روش‌های کشاورزی و افزایش تاب‌آوری گیاهان کمک کند. گالگا (Galega officinalis L.) گیاهی علفی و چند ساله متعلق به تیره پروانه‌آسا می‌باشد. قسمت هوایی آن حاوی مجموعه‌ای از مواد کاهنده قند خون می‌باشد و از این گیاه به عنوان ضد دیابت استفاده می‌شود. علاوه بر کاربردهای زراعی، گالگا دارای خواص دارویی نیز است. در طب سنتی، از آن برای درمان بیماری‌های مختلف از جمله دیابت، مشکلات گوارشی و التهابات استفاده می‌شود. گیاه گالگا به عنوان یک منبع ارزشمند پروتئین و علوفه، به خاطر ویژگی‌های مرفولوژیک و عملکردی‌اش در شرایط نامساعد محیطی مورد توجه قرار گرفته است. این تحقیق با هدف بررسی واکنش‌های محصول و اجزای عملکرد گیاه گالگا به تیمار تنش شوری و روش‌های مختلف کاشت انجام شد.
مواد وروش‌ها: این آزمایش به‌صورت طرح بلوک‌های کامل تصادفی با سه تکرار در سه محیط کشت (گلخانه، گلدان معمولی در هوای آزاد و گلدان بزرگ در مزرعه) در سال زراعی 1402 در دانشگاه ارومیه اجرا شد. تنش شوری در سه سطح، 1/0 (شاهد)، 5 و 10 دسی-زیمنس بر متر بود. صفات مختلف زراعی مانند ارتفاع بوته، تعداد شاخه فرعی، تعداد شاخه اصلی، عملکرد بیولوژیک، کارآیی مصرف آب بیوماس، عملکرد دانه، کارآیی مصرف اب عملکرد دانه، وزن 1000 دانه، وزن خشک بذر با غلاف، تلاش بازآوری، شاخص برداشت، سدیم، پتاسیم و پرولین اندازه گیری شد. تجزیه و تحلیل آماری داده‌ها با استفاده از نرم‌افزار SAS (نسخه 1/9) و MATATC انجام و مقایسه میانگین‌ها نیز توسط آزمون LSD در سطح احتمال خطای پنج درصد انجام شد.
یافته‌ها: تنش شوری در هر سه محیط کشت سبب کاهش ارتفاع بوته، تعداد شاخه فرعی، تعداد شاخه اصلی، بیوماس، عملکرد، اجزای عملکرد دانه پتاسیم برگ گالگا و افزایش میزان پرولین و سدیم نسبت به شاهد شد. در شرایط گلخانه بوته‌ها وارد مرحله زایشی نشدند. بیشترین ارتفاع بوته (66/71 سانتی‌متر) و وزن 1000 دانه (37/5 گرم) در تیمار شاهد و کشت مزرعه‌ای و کمترین ارتفاع (64/31 سانتی-متر) و وزن هزار دانه (33/4 گرم) در تنش شوری 10 دسی زیمنس بر متر و در شرایط کشت گلدانی هوای آزاد بدست آمد. در شرایط بدون شوری (شاهد)، بیشترین و کمترین عملکرد دانه (82/5 و 35/2 گرم در بوته) به ترتیب در شرایط مزرعه و گلدانی هوای آزاد بدست آمد.
نتیجه‌گیری: کشت گلدانی گالگا در هوای آزاد در شوری 5 و 10 دسی‌زیمنس بر متر، حداکثر عملکرد را تولید کرد و همچنین به دلیل برتری کارآیی مصرف آب براساس عملکرد دانه، این روش کشت برای شرایط شور پیشنهاد می‌گردد.

Abstract
Introduction: Salinity stress is one of the most important environmental challenges that is increasingly felt, especially in arid and semi-arid regions of the world. Different plants respond differently to salinity, and understanding these responses can help improve agricultural practices and increase plant resilience. Galega (Galega officinalis L.) is a herbaceous perennial plant belonging to the family Lepidaceae. Its aerial part contains a set of substances that lower blood sugar and this plant is used as an antidiabetic. In addition to agricultural applications, Galega also has medicinal properties. In traditional medicine, it is used to treat various diseases including diabetes, digestive problems, and inflammation. Galega, as a valuable source of protein and fodder, has been considered due to its morphological and functional characteristics under adverse environmental conditions. This study was conducted to investigate the responses of the yield and yield components of Galega to salinity stress treatment and different planting methods.
Materials and methods: This experiment was conducted in a randomized complete block design with three replications in three cultivation environments (greenhouse, regular pot in the open air and large pot in the field) in the 2024 crop year at Urmia University. Salinity stress was at three levels, 0.1 (control), 5 and 10 dS/m. Various agronomic traits such as grain yield, morphological traits, sodium, potassium and proline were measured. Statistical analysis of the data was performed using SAS software (version 9.1) and MATATC and comparison of means was also performed using the LSD test at a 5% error probability level. For data obtained through counting (number of secondary and main branches), square root transformation was performed using SPSS software (version 16) and then mean comparison was performed.
Results: Salinity stress in all three cultivation conditions caused a reduction in plant height, number of secondary and main branches, biomass, yield, yield components and leaf potassium and an increase in proline and sodium content compared to the control. In the greenhouse conditions, the plants did not enter the reproductive stage. The highest plant height (71.66 cm) and weight of 1000 seeds (5.37 g) were obtained in field at control plants and the lowest plant height (31.64 cm) and weight of 1000 seeds (4.33 g) were obtained in outdoor pot at the salinity of 10 dS/m. Galga field cultivation produced the highest seed yield (5.82 g per plant) and outdoor pot cultivation produced the lowest seed yield (2.35 g per plant) in no-salt conditions.
Conclusion: The comparison between salinity stress treatments showed that Galga pot cultivation in outdoor at salinity of 5 and 10 dS/m produced the maximum yield and also due to the superiority of water consumption efficiency based on seed yield, this cultivation method is recommended for saline conditions.
