Mini propagation is a new method to produce potato. A factorial experiment based on completely randomized block design with three replications was conducted to investigate the effect of two temperature levels (18 and 25°C) and six hormone treatments (H₁: 0% of ethanol + 0 mg/l of gibberellic acid, H₂: 0% of ethanol + 10 mg/l of gibberellic acid, H₃: 0.5% of ethanol + 0 mg/l of gibberellic acid, H₄: 0.5% of ethanol + 10 mg/l of gibberellic acid, H₅: 0.5% of ethanol + 20 mg/l of gibberellic acid, H₆: 0.5% of ethanol + 30 mg/l of gibberellic acid) on mini tubers of two varieties of potato (Agria and Santé). The longest sprouts were about 14.13 mm long and they were produced by Santé variety at 18°C and H₁ hormone level. Sprouting percentage was higher in Santé (75.69%) than in Agria (59.72%). The highest average percentage of sprouted tubers (95%) was achieved at the temperature of 18°C and with H₄ hormone treatment. Santé had the shortest dormancy duration by using H₁ hormone level at 18°C. Applying H₆ hormone level at 18°C produced more sprouts per tuber in Santé. Santé was better than Agria with or without hormone treatment in respect of all measured traits. Higher GA concentration accelerates tuber sprouting in both varieties.
