چکیده مقاله :
کاربرد تنظیم کننده‌های رشد از روش‌های مهم در کاهش آثار سوء تنش خشکی و به دست آوردن محصول مناسب در شرایط کمبود آب می باشد. این پژوهش به‌منظور تعیین اثر بخشی محلول‌پاشی با سایکوسل در تخفیف اثرات تنش خشکی در جو رقم کویر انجام شد. آزمایش به صورت فاکتوریل در قالب طرح پایه بلوک‌های کامل تصادفی در چهار تکرار انجام و تیمارهای آزمایش شامل سایکوسل با غلظت‌های 500 ، 1000 و 1500 میلی‌گرم بر لیتر و تنش خشکی در سه سطح آبیاری معمول، قطع آبیاری در مرحله ساقه‌دهی و خوشه‌دهی بود. تنش خشکی تمامی صفات مورد ارزیابی را تحت تأثیر منفی خود قرار داد. کاربرد سایکوسل در شرایط تنش خشکی موجب افزایش معنی‌دار عملکرد و اجزای عملکرد و کاهش ارتفاع بوته شد. محلول‌پاشی گیاه با غلظت 1500 میلی‌گرم بر لیتر سایکوسل موجب تعدیل وضعیت گیاه در برابر تنش خشکی شد و از این رو، استفاده از این غلظت برای دستیابی به عملکرد مطلوب در جو رقم کویر در شرایط تنش خشکی قابل توصیه می باشد.
Application of plant growth regulators is one of the most important methods to reduce the effects of drought stress to obtain suitable growth under water deficit conditions. The currecnt research objective is investigat the effect of cycocel foliar application on alleviation of drought stress concequences on growth traits of barley cv. Kavir .The experiment was conducted as factorial in randomized complete block design with four replications. The experiment treatments included cycocel with concentrations of 500, 1000, 1500 mg/L, drought stress at three levels of normal irrigation, irrigation cut-off in stemming and flowering stage. Drought stress negatively affected all evaluated traits. Cycocel application under drought stress significantly increased yield and yield components and reduced plant height. Foliar application with 1500 mg/L concentration of cycocel caused the plant to be subjected to drought stress. Applying 1500 mg/L cycocel can be recommended to reach optimum grain yield of barley cv. Kavir subjected in drought stress.
