In this research the effect of application of different levels of folic acid and time on some quality and agronomic characteristics of strawberry (cultivar Paros) was investigated. The plants were treated by folic acid with concentrations of 0, 20 and 40 mM at two stages (30 days after planting and first blooming) as a factorial experiment using a randomized complete block design with four replications in the greenhouse conditions. Results showed that fruits of treated plants by folic acid, as compared to the control treatment improved quality and agronomic characteristics. Application of folic acid increased yield, weight of primary and secondary fruits and number of their achenes, total soluble solid, inducing sugar, titratable acidity, anthocyanin, phenol, and vitamin C. The most effective treatment with the best spraying time was 40 mM folic acid at 30 days after planting. The present study is the first evidence that folic acid enhances fruit quality and yield of strawberry.

کارآرایی اسید فولیک روی بهبود عملکرد و کیفیت محصول توت فرنگی

Abstract [Persian]

در این تحقیق زمان کاربرد اسید فولیک و سطوح مختلف آن روی برخی ویژگی­های کمی و کیفی توت فرنگی رقم پاروس بررسی شد. گیاهان به وسیله اسید فولیک با غلظت صفر، 20 و 40 میلی مول در دو مرحله (30 روز بعد از کشت نشاء و اولین گلدهی) در قالب طرح بلوک­های کامل تصادفی در چهار تکرار در شرایط گلخانه تیمار شدند. نتایج نشان دادند که میوه­های تیمار شده با اسید فولیک از نظر کمیت و کیفیت نسبت به میوه­های تیمار شاهد برتر هستند. کاربرد سطوح مختلف اسید فولیک، عملکرد، وزن میوه اولیه و ثانویه و تعداد فندقه آن­ها، کل مواد جامد محلول، قندهای احیا کننده، اسیدهای قابل تیتراسیون، آنتوسیانین، فنل و ویتامین ث را افزایش داد. در نهایت بهترین تیمار این آزمایش، کاربرد اسید فولیک  به میزان  40 میلی مول  در 30 روز بعد از کشت نشاء تشخیص داده شد. تحقیق حاضر اولین گزارش در باره اثر اسید فولیک بر افزایش ویژگی­های کمی و کیفی توت فرنگی به شمار می­رود.
