چکیده

زعفران یکی از ارزشمندترین و گران­بهاترین گیاهان دارویی است که در مناطق خشک و نیمه­خشک کشت می‌شود. جهت بررسی اثر تراکم کاشت بر کیفیت گل دو نوع زعفران ایرانی و اسپانیایی،آزمایشی طی دو سال زراعی 93-1392 و 94-1393 در مزرعه تحقیقاتی دانشکده کشاورزی دانشگاه فردوسی مشهد انجام شد. آزمایش به صورت فاکتوریل در قالب طرح بلوک­های کامل تصادفی با سه تکرار انجام گرفت و نتایج دوسال بصورت فاکتوریل اسپلیت پلات در زمان آنالیز گردید. فاکتورA: نوع بنه (ایرانی و اسپانیایی) و فاکتور D: تراکم کاشت (40، 48 و 60 بنه در متر مربع) در نظر گرفته شد. اثرات نوع بنه بر شاخص­های کیفی، به جزء کروسین، معنی­دار نبود. بیشترین مفدار کروسین (01/202)، پیکروکروسین (23/72) و سافرانال (30/36) در تراکم 40 بنه در متر مربع (d1) حاصل شد. همچنین بیشترین مقدار کروسین (73/200)، پیکروکروسین (24/71) و سافرانال (91/28) متعلق به بنه­های اسپانیایی (a2) بود، در حالی­که بیشترین تعداد گل (21/27 عدد بر متر مربع)، وزن تر گل (58/13گرم بر متر مربع) و وزن خشک زعفران (144/0 گرم بر متر مربع) را بنه­های ایرانی (a1) تولید کرد. به­طورکلی، می­توان گفت که بنه­های اسپانیایی (از نظر کیفی) و ایرانی (از نظر کمی) برتری نشان دادند.
