چکیده

باکتری های حل کننده فسفات، تثبیت کننده نیتروژن و قارچ های میکوریز آربوسکولار نقش مهمی در تامین نیاز گیاهان به عناصر غذایی دارند. به منظور بررسی اثر کارایی باکترهای محرک رشد گیاهان و قارچ های میکوریز آربوسکولار بر صفات فیزیولوژیکی تره ایرانی آزمایش مزرعه­ای در قالب طرح بلوک های کامل تصادفی با 10 تیمار و 3 تکرار در مزرعه به اجرا در آمد. در این آزمایش بذر تره ایرانی توده محلی تبریز با باکتری­های موجود در کودهای زیستی بارور 2 (Pseudomonas putida  و Pantoea agglomerans P5) و نیتروکسین (Azotobacter sp.)، باکتری­های Azospirillum AC46I، Azospirillum AC49VП، باکتری­هایP. fluorescens Chao،P. putida Tabriz  و دو گونه قارچ میکوریز آربوسکولار Glomus versiforme، G. intraradices تلقیح و کاشته شد. نتایج نشان داد که شاخص­های محتوای کلروفیل، ویتامین ث، پلی­فنل کل، فسفر و نیتروژن و درصد کلنیزاسیون در سطح احتمال یک درصد و اسیدپیروویک، پروتئین­های محلول و مقدار جذب فسفر و نیتروژن در سطح احتمال 5 درصد تحت تاثیر تیمار کودهای زیستی معنی­دار شد.ه است. تیمار تلفیقی قارچ­های میکوریز به همراه باکتری­های تثبیت‌کننده نیتروژن به ویژه Azotobacter  نتایج بهتری را نسبت به بقیه تیمارهای میکروبی در افزایش صفات کیفی تره ایرانی داشته به طوری که این باکتری ها باعث افزایش کارایی قارچ های میکوریز در تیمارهای تلفیقی شد که دلیل آن تغذیه بهتر و بیشتر مواد غذایی به ویژه فسفر و نیتروژن می باشد.

چکیده [English]

Phosphate solubilizing and nitrogen-fixing bacteria and mycorrhizal fungi play an important role in the supply of nutrients in plants. To evaluate the efficacy of plant growth promoting bacteria and arbuscular mycorrhizal fungi (AMF) on physiology traits of Tareh Irani a field experiment in a randomized complete block design with 10 treatments and 3 replications was conducted. In this experiment tareh Irani seeds, (Tabriz landrace) inoculated with bacteria 1) P. putida P13, Pantoea agglomerans P5 (the biofertilizer Barvar2), 2) Azotobacter sp. (in biofertilizer Nitroxin), 3) bacteria Azospirillum sp. AC46 I, Azospirillum sp. AC49VП, 4) bacteria P. fluorescens Chao, P. putida Tabriz 5) two species of AMF, Glomus versiforme, G. intraradices. Results indicated that the colonization percent, percentage of chlorophyll, vitamin C content, total poly phenoles, phosphorus and nitrogen (p ≤ 0.01) and pyruvic acid, soluble proteins, (p ≤ 0.05) were affected by biofertilizers. Combination of mycorrhizal fungi and nitrogen-fixing bacteria (Azotobacter sp.) was better than other biofertilizer treatments in aspect of improving of quantity and quality traits in Tareh Irani. So that the bacteria can increase the efficiency of mycorrhizal fungi treatments were combined because of better nutrition and more food is especially phosphorus and nitrogen.
