چکیده

به‌منظور بررسی بستر­های کشت جایگزین پیت بر جوانه­زنی و تولید نشاء توتون به روش شناور، آزمایشی در خزانۀ توتون به اجرا درآمد. تیمارها شامل بسترهای مختلف کشت، تشکیل‌شده از مقادیر متفاوت پیت، ورمیکولیت، خاک مزرعه، کود دامی، ماسۀ بادی، کمپوست پوست درخت و ضایعات کارخانۀ چای بودند. اختلاف معنی­داری بین بستر­های مختلف کشت از لحاظ صفات درصد جوانه‌زنی، سرعت جوانه­زنی، توان جوانه­زنی، بنیۀ طولی گیاهچه، بنیۀ وزنی گیاهچه، قطر طوقه، وزن خشک ریشه­چه و وزن خشک گیاهچه وجود داشت. بیشترین درصد جوانه­زنی، سرعت جوانه­زنی، توان جوانه­زنی و بنیۀ طولی گیاهچه در تیمار پیت 50 درصد + ورمیکولیت 25 درصد + خاک مزرعه 25 درصد و بیشترین میانگین­های قطر طوقه و وزن خشک ریشه­چه، وزن خشک گیاهچه و بنیۀ وزنی گیاهچه در تیمار کمپوست پوست درخت 50 درصد + خاک مزرعه 25 درصد + کود حیوانی 25 درصد، مشاهده شدند.

چکیده [English]

In order to study growing medium to replace peat in float system for improving germination and seedling production, an experiment was conducted in tobacconursery field. The treatments were peat, vermiculite, field soil, manure, sand, tree cortex compost and tea residue. There were significant differences between growing mediums in terms of germination percentage, germination rate, germination vigor, seedling length vigor, seedling weight vigor, collardiameter, radicle dry weight and seedling dry weight. The highest germination percentage, germination rate, germination vigor and seedling length vigor were observed in treatment of peat 50%+vermiculite 25%+field soil 25%. The highest collar diameter, radicle dry weight, seedling dry weight and seedling weight vigor were found in treatment of tree cortex compost 50%+ field soil 25%+ manure 25%.
