چکیده مقاله :

اين تحقيق به منظور بررسی پتانسیل تولید مینی تیوبر از میکروتیوبرهای ارقام مختلف سیب زمینی در شرایط گلخانه ای، در ایستگاه تحقیقات کشاورزی و منابع طبیعی اردبیل در سال 1389 اجرا گرديد. میکروتیوبرهای کوچک تر از یک گرم از هشت رقم سیب زمینی (ساتینا، کایزر، مارفونا، لوتا، آگریا، مارکیز، هرمس و ساوالان) در بستر کاشت بیولان و پوکه معدنی به نسبت حجمی 1:1 در نایلون‌های گلدانی 10×10 سانتی‌متر براساس طرح کاملا تصادفی در سه تکرار کشت گردید. نتايج تجزیه واریانس حاصل از اندازه گيري صفات نشان داد که ارقام سیب زمینی از نظر تمام صفات مورد مطالعه دارای اختلاف معنی دار بودند. بیشترین تعداد مینی تیوبر در متر مربع مربوط به رقم آگریا، وزن مینی تیوبر در متر مربع و متوسط اندازه مینی تیوبر مربوط به رقم ساوالان، تعداد و وزن مینی تیوبر بزرگ تر از 10 گرم مربوط به ارقام ساوالان و ساتینا، تعداد و وزن مینی تیوبر بین 7-10 گرم مربوط به ارقام آگریا و ساتینا بود

چکیده انگلیسی:

This research was conducted to evaluate mini-tubers production potential in micro-tuber different potato cultivars under greenhouse conditions in Ardabil Agricultural and Natural Resources Research Station during 2010. Micro-tubers less than 1g of eight potato cultivars (Satina, Caesar, Marfona, Luta, Agria, Markies, Hermes and Savalan) were cultured on completely randomized design with three replications. The micro-tubers were planted in Biolan and Punch bed planting to volume ratio of 1:1 in plastic as pots 10×10 cm. Analysis of variance for measured traits showed that potato cultivars in all of traits had significant difference. The maximum mini-tuber number per m2 belonged to Agria cultivar; mini-tuber weight per m2 and mini-tuber size average belonged to Savalan cultivar; mini-tuber number and weight higher than 10 g belonged to Savalan and Satina cultivars; mini-tuber number and weight between 7-10 g belonged to Agria and Satina cultivars.
