| < p>این تحقیق به منظور بررسی تاثیر روکش بذر با ترکیبات عناصرکممصرف، محرکها و تنظیمکنندههای رشد بر سبزشدن، استقرار بوته و مراحل اولیه رشد چغندرقند در سال 1397 در دانشگاه محقق اردبیلی تحت شرایط گلخانه انجام شد. آزمایش به صورت فاکتوریل در قالب طرح بلوکهای کامل تصادفی با سه تکرار به مورد اجرا درآمد. فاکتورهای آزمایش شامل شستشوی بذر (شستشو و عدم شستشو)، رقم (شکوفا و پارس) و ترکیبات مختلف عناصرکممصرف، محرکهای رشد و هورمونها که شامل 5 تیمار به همراه یک تیمار شاهد (بدون روکش) بودند. مقایسه میانگین دادههای حاصل از آزمایش مشخص کرد در بین بذر هیبریدهای منوژرم چغندرقند، هیبرید پارس از نظر درصد استقرار نسبت به شکوفا برتر بود. نتایج این تحقیق نشان داد که روکشدار کردن بذر بعد از شستشوی آن موجب افزایش کارایی تیمارهای روکشدارکردن بذر چغندرقند شد. در بین تیمارهای مختلف روکش بذر تیمارهای 1 ([روی+منگنز+بور به ترتیب 9، 5/16 و 5/8 گرم در کیلوگرم بذر + اسید جیبرلیک+ اتیلن+ اسید سالسیک به ترتیب 2/1، 2 و 35/0 میلیلیتر در کیلوگرم بذر]) و تیمار 2 ([روی+منگنز+بور به ترتیب 9، 5/16 و 5/8 گرم در کیلوگرم بذر + اسید آمینه + هیومیک اسید + عصاره جلبک به ترتیب 8، 12 و 12 گرم در کیلوگرم بذر]) بیشترین تاثیر را در تسریع سبزشدن و بهبود رشد گیاهچه داشت و در این تیمارها حداکثر شاخص کلروفیل و عملکرد کوانتومی فتوسیستمII مشاهده گردید. | ||

| < p >The purpose of this study was to investigate the effect of seed coating with combinations of micronutrients, stimulants and growth regulators on emergence, plant establishment and early stages of sugar beet growth. This study was carried out in greenhouse conditions at Mohaghegh Ardabili University in 2018. Experiment was conducted as factorial in a completely randomized design with three replications. Seed washing (washing and not-washing), varity (Shekofa-Persian) and various combinations of micronutrients, stimulants and growth regulators which contains 5 were treated with a control (no cover-up) were the experimental factors. Comparison of the mean data from the experiment showed that among the sugar beet monogerm hybrids, Pars hybrid was superior in terms of establishment percentage. The results of this study showed that seed coating after washing increased the efficiency of sugar beet seed coating treatments. Among different treatments, seed coating treatments 1 [Zn+Mn+B (9, 16.5 and 8.5 g/ kg-1 seed Respectively)+ Gibberellic acid+ Ethylene+ Salicylic acid (1.2, 2 and 0.35 mL/ kg-1 seed, Respectively)] and 2 [Zn+Mn+B (9, 16.5 and 8.5 g/ kg-1 seed Respectively)+ Amino acid+ Humic acid + Seaweed extract (8, 12 and 12 g / kg-1 seed, Respectively)] had the most effect on accelerating emergence and improvement of seedling growth and maximum chlorophyll index and quantum yield of photosystem II were observed in these treatments. | ||
