چکیده

این تحقیق به‌منظور بررسی تأثیر پوشش بذر با مکمل‏های کود آلی تپروسین، کادوستیم و زاگرت بر سبزشدن و رشد گیاهچه چغندرقند انجام گرفت. آزمایش در سال 1395 در دانشگاه محقق اردبیلی تحت شرایط گلخانه‏ای به‌صورت فاکتوریل در قالب بلوک‏های کامل تصادفی در سه تکرار انجام شد. فاکتورهای آزمایش شامل شستشوی بذر (شستشو و بدون شستشو)، هیبرید (شکوفا و پارس) و مقادیر مختلف فرآورده‏های تپروسین، کادوستیم و زاگرت به همراه تیمار شاهد و تیمار چسب می‏باشند. نتایج نشان داد که تیمار شستشوی بذر موجب افزایش درصد سبزشدن، سرعت سبزشدن‏‏ و درصد استقرار بوته و کاهش زمان تا 10 و 90 درصد سبزشدن گردید. تیمارهای پوشش‏دار کردن بذر با 20 و 30 میلی‏لیتر زاگرت در هر کیلوگرم بذر، به ترتیب با 95 و 16/94 درصد سبزشدن نسبت به دیگر تیمارها برتری داشتند. درصد استقرار بوته در هیبرید پارس بیشتر از هیبرید شکوفا بود. در بین تیمارهای مختلف پوشش بذر، تیمار پوشش بذر با زاگرت نسبت به دیگر تیمارها از بیشترین مقدار سطح برگ و وزن خشک ریشه و برگ برخوردار بود. به طور کلی در این تحقیق پوشش‏دار کردن بذر با تپروسین و زاگرت باعث بهبود رشد گیاهچه و افزایش درصد استقرار بوته شد.

چکیده [English]

This study aimed to evaluate the effect of sugar beet (Beta vulgaris) seed coating with organic fertilizer of Teprosyn, Kadostim and Zagroot on the emergence and seedling growth characteristics as factorial in a completely randomized design with three replications in 2015 at the Faculty of Agriculture and Natural Resources of Mohaghegh Ardabili University under greenhouse conditions. The experiment factors included seed washing (washing without washing), hybrids (Shokoufa and pars) and different amounts of organic fertilizers of Teprosyn, Kadostim and Zagroot, with control and adhesive treatments. The results showed that seed washing treatment increased the percentage of emergence, velocity of emergence and the percentage of plant establishment, and decreased the time to 10 and 90% of the emergence. Percentage of seed emergence in seed coating treatments with Zagrot (20 ml per kg of seed), with 95% emergence, seed coating with Zagroot (30 ml per kg seed), with 94.16% emergence were superior to other treatments. The percentage of plant establishment in the Pars hybrid was higher than the Shokoufa. Among different treatments of seed coating, seed treatment with Zagroot, had the highest leaf area and root and leaf dry weight. In general, in this research, seed coating with Teprosyn and Zagroot improved seedling growth and increased plant establishment.
