| چکیده | ||
| به منظور بررسی تاثیر کاربرد باکتری های آزاد زی تثبیت کننده نیتروژن و زمان محلولپاشی کود نیتروژنه بر میزان مشارکت ذخایر ساقه در عملکرد دانه، سرعت و طول دوره پر شدن دانه تریتیکاله، آزمایشی به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی در سه تکرار در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه محقق اردبیلی در سال 1391 انجام گردید. تیمارها شامل زمان محلولپاشی کود نیتروژنه در چهار سطح (عدم محلولپاشی، محلولپاشی در زمان چکمه پوش، ظهور سنبله و دوره پرشدن دانه) و تلقیح بذر با باکتریهای محرک رشد در چهار سطح (عدم تلقیح بذر با باکتریهای محرک رشد، تلقیح بذر با ازتوباکتر کروکوکوم استرین 5، آزوسپریلوم لیپوفروم استرین OF و سودوموناس پوتیدا استرین 9) بود. نتایج نشان داد عملکرد و اجزای عملکرد دانه، سرعت و طول دوره موثر پرشدن دانه به طور معنیداری تحت تاثیر تلقیح بذر با باکتری های آزادزی تثبیت کننده و محلولپاشی کود نیتروژنه قرار گرفت. حداکثر وزن دانه (0/054 گرم) و طول دوره موثر پرشدن دانه (34/17 روز) از محلولپاشی در زمان چکمه پوش در تلقیح بذر با ازتوباکتر بدست آمد. بیشترین مشارکت ذخایر ساقه در عملکرد دانه (30/63 درصد) در حالت عدم تلقیح بذر با باکتریهای محرک رشد و عدم محلولپاشی کود نیتروژنه و کمترین آن (8/12 و 8/13 درصد) از محلولپاشی در زمان چکمه پوش در تلقیح بذر با ازتوباکتر و محلول پاشی در مرحله ظهور سنبله در تلقیح بذر با ازتوباکتر بدست آمد. به نظر می رسد که به منظور افزایش عملکرد، سرعت و طول دوره موثر پرشدن دانه می توان پیشنهاد کرد که تلقیح بذر با ازتوباکتر و محلول پاشی با کود نیتروژنه در زمان چکمه پوش به کار برده شود. | ||

| چکیده [English] | ||
| In order to investigate the effects of free living nitrogen fixing bacteria application and time of nitrogen spraying on contribution of stem reserves in grain yield, rate and effective grain filling period of Triticale, a factorial experiment was conducted based on a randomized complete block design with three replications in Research farm of the Faculty of Agriculture, University of Mohaghegh Ardabili in 2012. Treatments consisted of different nitrogen spraying times in four levels (no spraying as control, spraying in boot stage, ear emergence, grain filling period) and seed inoculation with plant growth promoting rhizobacteria in four levels containing (without inoculation as control, seed inoculation with Azotobacter chroococcum strain 5, Azospirillum lipoferum strain OF, Psedomunas putida strain 9). Results indicated that spraying time of nitrogen fertilizer and seed inoculation with free living nitrogen fixing bacteria had significant effects on yield, yield components, rate and effective grain filling period of Triticale. Maximum of grain weight (0/054 gr) and effective grain filling period (34.17 days) were obtained in seed inoculation with Azotobacter× nitrogen spraying in boot stage. Maximum of contribution of stem reserves in grain yield (30.63 %) was obtained in no nitrogen spraying × no seed inoculation with PGPR and minimum of it (8.12 and 8.13 %) were obtained in nitrogen spraying in boot stage × seed inoculation with Azotobacter and spraying in ear emergence × seed inoculation with Azotobacter. It seems that in order to increase the grain yield,rate and effective grain filling period of Triticale, it can be suggested that nitrogen spraying is applied in boot stage and seed inoculation with Azotobacter | ||
