چکیده
مرزه کاربردهای متعددی در طب سنتی داشته و محلول پاشی الکل روی قسمت‌های هوایی گیاهان به عنوان یکی از راهکارهای جدید برای افزایش رشد و عملکرد آنها مطرح می‌باشد. در این پژوهش، اثر محلول‌پاشی متانول و اتانول بر صفات مورفولوژیکی و فیزیولوژیکی گیاه دارویی مرزه در شرایط گلدانی در قالب طرح کاملاً تصادفی با 10 تیمار شامل محلول پاشی غلظت های 10، 20، 30 و 40% حجمی متانول و اتانول، آب مقطر و شاهد (بدون محلول پاشی) ارزیابی شد. محلول‌پاشی سطوح مختلف اتانول و متانول و به خصوص غلظت 40٪ آنها توانست در بسیاری از صفات مورد ارزیابی نقش مثبتی نشان دهد. نقش مثبت اتانول 40% در افزایش وزن تر و خشک برگ، قطر یقه، وزن تر ساقه و گیاه و متانول 40% در افزایش وزن خشک ساقه و گیاه، ارتفاع بوته و تعداد برگ بارز بود. با افزایش غلظت الکل های مصرفی، شاخص کلروفیل برگ افزایش یافت ولی افزایش قابل توجهی در طول برگ دیده نشد. همچنین، اثر افزایشی محلول پاشی آب و متانول بر فاصله اولین گره از یقه دیده شد و برعکس، اثر کاهشی متانول و آب بر پهنای تاج پوششی مشاهده شد. بنابراین، با توجه به اثر مثبت محلول پاشی متانول و اتانول در افزایش رشد رویشی و شاخص های رشدی گیاه دارویی مرزه، استفاده از محلول های آبی این الکل ها قابل توصیه است.

چکیده [English]
Savory (Satureja hortensis L.) has various applications in traditional medicine. Alcohol spraying on plants foliage is considered as one of the new methods for improvement of their growth and yield. In current study, the effect of methanol and ethanol spraying on morphological and physiological traits of savory has been studied in pot conditions based on completely randomized design with 10 treatments including spray concentrations of 10, 20, 30 and 40% (v/v) methanol and ethanol, distilled water and no spraying. Ethanol and methanol spraying specially in 40% concentration could be improving in most of studied traits. Ethanol 40% had a positive role in increasing of leaf dry and fresh weight, crown diameter, plant and stem fresh weight and methanol 40% was effective in plant and shoot dry weight, plant height and leaf number improvement. Increasing in alcohol concentrations caused chlorophyll content increment, but not leaf length. Also, spraying with distilled water and methanol caused more crown distance to first node; but less canopy width. Therefore, implementation of methanol and ethanol solutions is recommending increasing growth and growth indices of savory.
