چکیده

استفاده از پتانسیل میکروبی خاک از جمله قارچ های میکوریز آربوسکولار (AMF)برای بهبود رشد و تغذیه گیاه بطور گسترده ای مورد توجه قرار گرفته است. این مطالعه به منظور بررسی تأثیر قارچ های میکوریز آربوسکولار بر رشد و درصد مواد مؤثره نعناع فلفلی تحت شرایط گلخانه ای در قالب طرح کاملاً تصادفی با 4 تیمار قارچ میکوریز آربوسکولار انجام شد. تیمارهای تلقیحی شامل 1) شرایط بدون تلقیح (C)، 2) گلوموس فسیکولاتوم (Gf)، 3) گلوموس اینترارادیسز (Gi) و 4) گلوموس موسه (Gm) بودند. در پایان دوره رشد برخی پارامترهای رشدی شامل ارتفاع، قطر ساقه، تعداد شاخه جانبی، تعداد برگ، وزن تر و خشک برگ و همچنین درصد مواد مؤثره و درصد کلنیزاسیون ریشه نعناع فلفلی اندازه گیری شدند. نتایج نشان داد تلقیح با قارچ های میکوریز آربوسکولار اثر معنی داری (05/0P≤)، بر روی پارامترهای اندازه گیری داشته است. تلقیح با قارچ های میکوریز آربوسکولار، ارتفاع گیاه، قطر ساقه، تعداد شاخه های جانبی، تعداد برگ، ماده تر و خشک برگ، درصد کلونیزاسیون ریشه و محتوی (25 درصد) و عملکرد اسانس (28 درصد) را افزایش داد. منتول، منتون و 1و 8-سینئول بالاترین فراوانی را در مواد موثره نعناع تشکیل دادند. تأثیر قارچ-های میکوریز آربوسکولار بر وزن خشک ریشه و درصد کلونیزاسیون ریشه معنی دار (05/0P≤) بود. بیشترین و کمترین درصد کلونیزاسیون ریشه (به ترتیب 47 و 0 درصد) در گیاهان تلقیح شده با Gf و تیمار شاهد مشاهده گردید.

چکیده [English]

Introduction: Arbuscular mycorrhizal symbiosis is formed by approximately 80% of the vascular plant species in all terrestrial biomes. Using soil microbial potential including arbuscular mycorrhizal fungi (AMF) has been widely considered for improving plant growth, yield and nutrition. Medicinal herbs are known as sources of phyto chemicals or active compounds that are widely sought worldwide for their natural properties. Members of the Lamiaceae family have been used since ancient times as sources of spices and flavorings and for their pharmaceutical properties. Peppermint (Mentha piperita) has a long tradition of medicinal use, with archaeological evidence placing its use at least as far back as ten thousand years ago. Essential oils - are volatile, lipophilic mixtures of secondary plant compounds, mostly consisting of monoterpenes, sesquiterpenes and phenylproponoids.Arbuscularmycorrhizal fungi with colonizing plant roots improve nutrient uptake as well as improving essential oil yield of medicinal plants by increasing plant biomass. The aim of the present study was to evaluate the effect of AMF inoculation on essential oil content and some growth parameters of peppermint (Mentha piperita) plant under glasshouse condition.
Materials and Methods: This study was performed on a loamy sand soil. The samples were air-dried, sieved (
