چکیده

چکیده-تولید فلفل دلمه­ ای در سالهای اخیر به دلیل افزایش تقاضای مصرف کننده افزایش چشمگیری داشته است. خصوصیات فیزیولوژیکی فلفل دلمه­ ای در گلخانه­ های تحقیقاتی دانشگاه صنعتی اصفهان تحت تیمارهای قارچ arbascularmycorrhiza گونه lomusintraradices(AMF) و سطوح مختلف آمینواسید (AA) ارزیابی شدند. تیمارها شامل AMF1 (بدون مایه زنی میکوریزا) به عنوان شاهد، AMF2 با1000 اسپور و AMF3 با 2000 اسپور مایکوریز و 4 غلظت شاهد (C، بدون امینو اسید)، 3 گرم(AA1)، 5/4گرم (AA2) و 6 گرم(AA3) امینواسید بودند. نتایج نشان داد که تلقیح مایکوریز و مخلوط آمینواسید، وزن تر و خشک ریشه و شاخساره را افزایش می­دهد. کاربرد قارچ، تعرق، میزان کلروفیل و غلظت فسفر و پتاسیم را تحت تاثیر قرار نداد اما فتوسنتز با کاربرد AMF بهبودیافت. همچنین کیفیت میوه تحت تیمارهای AMF2 و AMF3 بهبود یافت. در نهایت با افزایش غلظت آمینواسید و 1000 اسپور قارچ تاثیرات مثبتی در رشد فلفل دلمه ای مشاهده شد.
