تأثیر اندازه و خواب غده بذری بر جوانه‌زنی و عملکرد مینی‌تیوبر سیب‌زمینی

Potato is a main and strategically crops in Iran. In order to evaluate the effects of seed tuber size and dormancy on germination and yield potato minituber, an experiment was carried out in spring 2013 in Jolge-rokh located in Torbat-e-heidry County in spring 2013. In this experiment was used the randomized complete block design with one treatment, four replications. Treatment levels experiment included use of medium sprouting minituber (12-35mm diagonal), large dormancy minituber (d>35mm) and tiny dormancy minituber (d<12mm). The results showed traits modules affected on size and dormancy tuber difference significantly (P≤0.05).Highest emergence percentage (96.75%) and tuber yield (680gr) on medium sprouting tuber and less emergence percentage (12.25%) and yield (175gr) on tiny dormancy tuber was observed. Total number tuber of medium sprouting tuber and large dormancy minituber was not different significant (P≤0.05), but there is difference significantly with tiny minituber. Result this experiment showed highest emergence percentage, yield and number tuber belong to medium sprouting minituber.
