چکیده

در این تحقیق، کارایی 4 سویه فلاوباکتریوم که در طی آزمایش‌های گذشته از ریزوسفر گندم در ایران جداسازی و شناسایی شده بودند و بر اساس خصوصیات محرک رشدی غربالگری شده بودند، در افزایش عملکرد گندم در پنج استان کشور مورد ارزیابی قرار گرفت. سویه‌های مورداستفاده شامل F9, F11, F40 متعلق به گونهFlavobacterium odoratum و F21 متعلق به گونه F.indoltheticum بودند. باکتری‌ها تا رسیدن به جمعیت مورد نظر تکثیر شده و سپس به‌صورت مایع فرموله شده و در آزمایش‌ها مورد استفاده قرار گرفتند. برای کشت از ارقام اصلاح شده محلی استفاده شد و میزان کودهای شیمیایی بر اساس نتایج تجزیه خاک‌ها مصرف شد. پس از برداشت گیاهان شاخص‌های عملکرد دانه، عملکرد کل (دانه +کاه)، وزن هزار دانه، ارتفاع گیاه، تعداد خوشه در هر متر مربع، تعداد دانه در خوشه و طول خوشه اندازه‌گیری شدند. نتایج نشان داد که سویه‌های مورد استفاده در اکثر استان‌ها سبب افزایش رشد و عملکرد گندم شدند.
