| یکی از مهم‌ترین زمینه‌های تحقیقی در گیاهان دارویی، بررسی اثر تنش‌های محیطی تأثیرگذار بر میزان عملکرد کمی و کیفی این گیاهان و یافتن راه‌کارهای بهبود تحمل به این تنش‌ها است. به‌منظور بررسی تأثیر پیش تیمار با باکتری Pseudomonas fluorescens و قارچ Trichoderma harzianum بر برخی شاخص‌های جوانه‌زنی و رشدگیاهچه‌ای رازیانه تحت تنش خشکی، آزمایشی به صورت فاکتوریل دو عاملی در قالب طرح پایه کاملاً تصادفی با چهار تکرار انجام شد. فاکتورهای آزمایش شامل تلقیح زیستی در 9 سطح (تلقیح با 4 سویه باکتری سودوموناس فلورسنت (PF2، PF16، CHA0 و PF56)، 4 سویه قارچ تریکودرما هارزیانوم (T13،T36، T39 و T43) و تیمار نشده (به عنوان شاهد)) و تنش خشکی در سه سطح (صفر، 3- و 6- بار) بود. شاخص‌های جوانه‌زنی و رشد گیاهچه ارزیابی شدند. نتایج نشان داد با کاهش پتانسیل اسمزی از صفر به 3- و 6- بار، جوانه‌زنی کاهش یافت. در سطح صفر بار بیشترین درصد جوانه‌زنی و طول ریشه‌چه و شاخص طولی بنیه گیاهچه از سویه باکتری -CHA0 و در هر سه سطح تنش، بیشترین میزان سرعت جوانه‌زنی، طول ساقه‌چه، وزن خشک گیاهچه و شاخص وزنی بنیه گیاهچه در بذور تیمار شده با سویه قارچ T39 به‌دست آمد. باکتری CHA0 توانست میزان رشد ریشه‌چه را به ترتیب در سطوح پتانسیل اسمزی صفر، 3- و 6- به ترتیب 46، 51 و 51 درصد نسبت به بذور تلقیح نشده افزایش دهد. با توجه به نتایج بدست آمده می‌توان نتیجه‌گیری نمود که تیمارهای قارچی و باکتریایی موجب افزایش شاخص های جوانه‌زنی و گیاهچه‌ای رازیانه در شرایط بهینه و تنش می‌شوند. | ||

| چکیده [English] | ||
| One of the most important research fields in medicinal plants is the effect of environmental stresses on quantitative and qualitative yield of these plants and finding solutions for improving tolerance to these stresses. In order to study the influence of seed biopriming with Pseudomonas fluorescent and Trichoderma harzianum fungi on some germination and seedling indices of fennel (Foeniculum vulgare L.) under drought stress an experiment was conducted as factorial based on a completely randomized design with four replications. Experimental factors included bio-inoculation in nine levels (inoculation with four strains of PF2, PF16, PF56 and CHA0 of Pseudomonas fluorescent, and T13, T36, T39 and T43 strains of T. harzianum and non-primed (control)) and three levels of drought stress (0, -3 and -6 bar imposed by PEG6000). Seed germination and seedling characteristics were evaluated. Results showed that by increasing the osmotic potential levels, germination indices were decreased. In 0 bar, the highest germination percentage, root length and seedling length vigor index were obtained from CHA0 treated seeds and in three levels of stress, the highest germination rate, shoot length, dry weight seedling and seedling weight vigor index related to seed treatments by T39. Compared to non-inoculated seeds, CHA0 increased the root growth by 46, 51 and 51%, respectively, at osmotic potential levels of 0, -3, and -6 bar, respectively. According to the obtained results, it can be concluded using fungus and bacterial treatments can be causing to increasing of germination and seedling characteristic of fennel seeds in optimum and stress condition. | ||
