چکیده

این آزمایش به منظور بررسی اثر پوششدار کردن بذر با عناصر ریزمغذی بر روی برخی شاخصهای جوانهزنی بذر گیاه دارویی همیشه بهار، انجام شد و در قالب طرح کاملأ تصادفی با چهار تکرار در سال 1393، در آزمایشگاه زراعت دانشکده کشاورزی دانشگاه گیلان به اجرا درآمد. تیمارهای پوششدهنده بهکار برده شده در این آزمایش شامل: بذور بدون پوشش (شاهد)، بذر پوششدار شده بدون عناصر ریزمغذی، پوشش بذر با عناصر آهن، منگنز و مس، پوشش بذر با عناصر مولیبدن، روی و بر و پوشش بذر با 6 عنصر ریز مغذی (آهن، منگنز، مس، مولیبدن، روی و بر) بودند. صفات درصد جوانهزنی، طول ریشهچه، طول ساقهچه، وزن تر و خشک ریشهچه، وزن تر و خشک ساقهچه، طول گیاهچه، وزن تر و خشک گیاهچه، شاخص بنیه بذر، شاخص طولی بنیه گیاهچه، ضریب آلومتریک، محتوای آب بافت گیاهچه، یکنواختی جوانه زنی، D10، D50 و D90 که به ترتیب مدت زمان رسیدن به 10، 50 و 90 درصد، فعالیت آنزیم آلفاآمیلاز در این آزمایش مورد بررسی قرار گرفت. نتایج نشان داد در بذرهای تیمار شده همیشه بهار با عناصر ریزمغذی، در اکثر صفات مورد بررسی اعم از درصد جوانهزنی، شاخص بنیه بذر، طول ریشهچه و ساقهچه و همچنین فعالیت آلفاآمیلاز افزایش معنیداری نسبت به تیمار شاهد مشاهده شد. در بین عناصر به کاربرده شده در این آزمایش، سه عنصر آهن، منگنز و مس بیشترین اثر گذاری را در فرایند جوانهزنی داشتند.

چکیده [English]

This experiment was conducted in order to investigate the effect of seed coating with micronutrients on germination characteristics of Marigold, and carried out  as complete randomized design (CRD) with four replications at agronomy laboratory in faculty of Agricultural Science, University of Guilan was performed in 2014. Experimental Treatments were including seed without coating, seed coating without micronutrients, seed coating with micronutrients (Fe, Mn, Cu), seed coating with micronutrients (Mo, Zn, B), and seed coating with micronutrients (Fe, Mn, Cu, Mo, Zn, B). Germination percentage, root length, shoot length, root dry weight, shoot dry weight, seedling length, fresh and dry weight of seedlings, seed vigor, vigor length l index, Allometric coefficient, seedling tissue water content , uniformity of germination, D10, D50 and D90, respectively, for the time they reach 10, 50 and 90%, amylase enzyme activity was studied in this experiment. Coating marigold seeds with micro-nutrients, significantly increased multiple parameters such as germination percentage, seed vigor index, root and shoot length and amylase activity in comparison with control treatment . Among the elements used in this experiment, 3 elements iron, manganese and copper had the greatest influence on the germination process.
