| مقاومت گسترده علفهای هرز به علفکشها، نمونهای بارز از تکامل سریع گیاهان در پاسخ به فشار انتخابی انسان است. در این پژوهش، 59 جمعیت یولافوحشی مشکوک به مقاومت به علفکشهای بازدارنده استیل کوآنزیم آ کربوکسیلاز در بهار سال 1397 از مزارع گندم چهار شهرستان استان خوزستان (اندیمشک، دزفول، شوش و شوشتر) جمعآوری شد. آزمایش در دو بخش غربالگری و پاسخ به دز به ترتیب با کاربرد دز توصیه شده (75 گرم ماده موثر در هکتار) علفکش پینوکسادن+فلوراسولام و دزهای صفر، 75/18، 5/37، 75، 150، 300 و 600 گرم ماده مؤثر در هکتار انجام شد. نتایج غربالگری نشان داد براساس دو شاخص رتبهبندی ادکینز و ماس به ترتیب 9 و 41 جمعیت به پینوکسادن+فلوراسولام مقاومت قطعی نشان دادند. براساس شاخصهای ادکینز و ماس، بهترتیب 7 و 41 جمعیت (86/11 و 49/69 درصد کل جمعیت) در گروه مقاوم (بهطورکلی دستههای مختلف R)، 21 و 8 جمعیت (59/35 و 56/13 درصد کل جمعیت) در گروه احتمالاً مقاوم (PR) یا مشکوک به مقاومت (R?) و 31 و10 جمعیت (54/52 و 95/16درصد کل جمعیت) در گروه حساس (S) به پینوکسادن+فلوراسولام قرارگرفتند. شاخص مقاومت به علفکش براساس وزن تر و درصد زنده-مانی برای جمعیتهای مورد بررسی بهترتیب بین 90/5-18/2 و 05/4-54/1 برآورد شد. نقشه پراکنش جمعیتهای مقاوم و حساس به علفکش، نشان داد که بیشترین تراکم جمعیتهای مقاوم در مزارع گندم دو شهرستان اندیمشک و شوش بود. به دلیل گسترش بسیار زیاد مقاومت در جمعیتهای یولافوحشی در مزارع گندم در آینده نزدیک یافتن جمعیت حساس به بازدارنده-های ACCase در مزارع گندم استان خوزستان کار دشواری باشد. | ||

| چکیده [English] | ||
| The widespread evolution of herbicide resistance in weeds represents a striking example of rapid plant adaptation in response to human-imposed selection pressure. In this study, 59 wild oat populations suspected of resistance to acetyl-coenzyme A carboxylase (ACCase) inhibiting herbicides were collected from wheat fields in four counties of Khuzestan province (Andimeshk, Dezful, Shush, and Shushtar) in the spring of 2018. The experiment was conducted in two parts: screening and dose-response, using the recommended dose of pinoxaden + florasulam herbicide (75 g a.i. ha-1) and doses of 0, 18.75, 37.5, 75, 150, 300, and 600 g a.i. ha-1, respectively. Screening results showed that, based on the two Adkins and Moss ranking indices, 9 and 41 populations showed definite resistance to pinoxaden+florasulam, respectively. Based on the Adkins and Moss index, 7 and 41 populations (11.86% and 69.49% of total populations) were in the resistant group (generally different R categories), 21 and 8 populations (35.59% and 13.56% of total populations) were in the probably resistant (PR) or suspected resistance (R?) group, and 31 and 10 populations (52.54% and 16.95% of total populations) were in the susceptible (S) group to pinoxaden + flurasolam, respectively. The herbicide resistance index based on fresh weight and survival percentage for the studied populations was estimated to be between 2.18-5.90 and 1.53-4.05, respectively. The distribution map of herbicide-resistant and herbicide-susceptible populations, based on the results of the screening experiment, showed that the highest density of resistant populations was in wheat fields in the two counties of Andimeshk and Shush. Given the extensive spread of resistance among wild oat populations in wheat fields, it is likely that identifying populations still susceptible to ACCase inhibitors in Khuzestan province will become increasingly difficult in the near future. | ||
