چکیده

با توجه به محدودیت مصرف کودهای شیمیایی برای سلامت انسان‌ها امروزه توجه بیش‌تری به کودهای زیستی گردیده است. به­منظور بررسی تاثیر ریزوباکتری‌های محرک رشد و قارچ میکوریز بر خصوصیات مورفولوژیکی، نشاسته و عناصر غذایی غده سیب‌زمینی در اردبیل، آزمایشی به‌صورت گلخانه‌ای – مزرعه‌ای در محوطه گلخانه‌ی دانشکده کشاورزی منابع‌طبیعی دانشگاه محقق اردبیلی به­صورت طرح پایه کاملاً تصادفی با چهار تکرار و هشت تیمار در سال 1397 اجرا گردید. تیمارها شامل آزسپریلوم، آزسپریلوم به همراه قارچ میکوریز، آزتوباکتر، آزتوباکتر به همراه قارچ میکوریز، سودموناس، سودموناس به همراه قارچ میکوریز، قارچ میکوریز و عدم تلقیح بود. پس از اتمام دوره رشد گیاه، متغیرهایی مانند ارتفاع گیاه، تعداد برگ، تعداد ساقه اندازه‌گیری شد. همچنین تعداد غده، درصد ماده خشک، نشاسته و NPK اندازه‌گیری شدند. نتایج نشان داد که تاثیر باکتری‌های محرک رشد و قارچ میکوریز بر عملکرد و کیفیت سیب‌زمینی رقم آگریا معنی‌دار بود. باکتری‌های سودوموناس فلورسنت وزن غده را در حدود 93/63 درصد افزایش دادند. بر اساس نتایج آزمایش، باکتری­های سودوموناس و ازتوباکتر تاثیر بهتری بر شاخص­های رشد سیب­زمینی رقم آگریا داشتند.

چکیده [English]

Given the limitations of chemical fertilizer use for human health, more attention has been paid to biofertilizers today. To investigate the effect of growth-promoting rhizobacteria and mycorrhizal fungi on morphological characteristics, starch, and nutrient elements of potato tubers in Ardabil, a field greenhouse experiment was conducted in the greenhouse of the Faculty of Agriculture and Natural Resources, University of Mohaghegh Ardabili, in a completely randomized basic design with four replications and eight treatments in 2018. The treatments included Azeprilum, Azeprilum with mycorrhizal fungi, Azotobacter, Azotobacter with mycorrhizal fungi, Pseudomonas, Pseudomonas with mycorrhizal fungi, mycorrhizal fungi, and no inoculation. After the plant growth period was completed, variables such as plant height, number of leaves, number of stems were measured. Also, the number of tubers, percentage of dry matter, starch, and NPK were measured. The results showed that the effect of growth-promoting bacteria and mycorrhizal fungi on the yield and quality of potato cultivar Agria was significant. Pseudomonas fluorescent bacteria increased tuber weight by about 63.93%. According to the experimental results, Pseudomonas and Azotobacter bacteria had a better effect on the growth indices of potato cultivar Agria.
