| چکیده | ||
| با وجود صفات مطلوب کیفی ذرت شیرین، کشت این گیاه به‌جهت ضعف برخی ویژگی‌های جوانه‌زنی، بنیه ضعیف، چروکیده‌گی بذر و استقرار ضعیف گیاهچه در خاک محدود می‌باشد، استفاده از ترکیبات معدنی در پوشش‌دهی بذر می‌تواند شاخص‌های جوانه‌زنی، ویژگی‌های گیاهچه‌ای و فیزیکی بذر ذرت شیرین را بهبود دهد. برای بهبود کارایی بذر ذرت شیرین با استفاده از پوشش‌دهی بذر، پژوهشی در آزمایشگاه فناوری بذر دانشکده کشاورزی دانشگاه یاسوج در سال 1397 به صورت فاکتوریل سه عاملی در قالب طرح کاملاً تصادفی با چهار تکرار 25 بذری اجرا شد. عامل اول شامل غلظت محلول‌های کیتوزان (صفر -اسید استیک 3/0 درصد، 5/0 و 75/0 درصد) ، عامل دوم صمغ عربی (صفر -آب مقطر و 4/0 درصد) و عامل سوم ترکیب پوششیV10K2.5P5 (ورمی‌کولیت (V) با نسبت وزنی 10 برابر وزن بذر، کائولن (K) با نسبت وزنی 5/2 برابر وزن بذر و پرلیت (P) با نسبت وزنی 5 برابر وزن بذر) و عدم وجود ترکیب پوششی بود. نتایج اثر برهمکنش صمغ عربی و ترکیب پوششی در سطح کیتوزان 5/0 درصد نشان داد که بیشترین شاخص طولی بنیه گیاهچه (24/183) مربوط به تیمار پوششی صمغ عربی 4/0 درصد و ترکیب پوششی V10K2.5P5 بود که با کمترین شاخص طولی بنیه گیاهچه (70/85) از تیمار پوششی صمغ عربی 4/0 درصد و عدم وجود ترکیب پوششی اختلاف معنی داری نشان داد. نتایج کلی آزمایش نشان داد که تیمار پوششی کیتوزان 5/0 درصد+ ترکیب پوششی V10K2.5P5+ صمغ عربی 4/0 درصد در مقایسه با دیگر تیمارهای آزمایش اثر بخشی بیشتری بر روی شاخص‌های جوانه‌زنی و ویژگی های بذر ذرت شیرین داشت. | ||

| چکیده [English] | ||
| In spite of optimal qualitative traits of sweet corn plant, its cultivation is limited due to some problems in germination, poor vigor, seed wrinkling and seedling weak establishment in the soil, using mineral compounds in seed coating could improve germination and seedling growth indices, and physical characteristics of sweet corn seeds. In order to improve efficacy of sweet corn seed using seed coating, this experiment was conducted based on three-factor factorial in a completely randomized design with four replications of 25 seeds at the laboratory at the Department of Agronomy and Plant Breeding, Yasouj University, Iran, in 2018. The first factor included the concentrations of chitosan solutions (zero- 0.3% acetic acid, 0.5 and 0.75%), the second factor was gum arabic (zero- distilled water and 0.4%) and the third factor was V10K2.5P5 coating composition (10, 2.5 and 5 fold to seed weight respectively in Vermiculite (V), kaolin (K) and perlite (P)) and no coating treatment. The interaction effect showed that that the highest seedling length vigor index (183.24) was related to the coating treatment of gum arabic 0.4% and coating composition of V10K2.5P5 that had a significant difference with a treatment that had the lowest seedling length vigor index (85.70) from the coating treatment gum arabic 0.4% and no coating composition. The overall results showed that the coating treatment of chitosan 0.5% + coating composition of V10K2.5P5 + gum arabic 0.4% was more effective treatment on germination indices and seedling and physical characteristics of sweet corn seeds compared to other treatments. | ||
