چکیده

امروزه به دلیل اثرات مضر کودهای شیمیایی تمایل به استفاده از ترکیباتی با اثرات سوء کمتر، مورد توجه قرار گرفته است. ازاین‌رو به‌منظور تأثیر هیدروالکل‌ها بر صفات کمی و کیفی گیاه دارویی ریحان (Ocimum basilicum L.)، در سال 1394 آزمایشی در قالب طرح کاملاً تصادفی با 3 تکرار در دانشکده کشاورزی دانشگاه فردوسی مشهد انجام شد. تیمارهای آزمایش شامل محلول‌پاشی اتانول (10، 20، 30 و 40% حجمی)، متانول (10، 20، 30 و 40% حجمی)، مخلوط یکسان متانول و اتانول (5، 15 و 25% حجمی) و تیمار شاهد (بدون محلول‌پاشی) بود. نتایج این تحقیق نشان داد که سطح محلول‌پاشی 40 درصد حجمی متانول در اکثر صفات مورفولوژیکی بر سایر سطوح برتری داشت. در بررسی صفات بیوشیمیایی، بیشترین میزان فعالیت آنتی‌اکسیدانی، فنل، کارتنوئید و کلروفیل b مربوط به اثر متقابل محلول‌پاشی متانول و اتانول 25% می‌باشد. همچنین بیشترین میزان کلروفیل کل و کلروفیل a با اتانول20% و بالاترین سطح قند با محلول‌پاشی با متانول 10% به‌دست آمد.
