In the present studies,two potatoes variety of Atlantic and Shepody were used to study effects of different storage conditions with different temperature on the vigor and the physiological characters of virus-free minitubers by storing them under cold(4～6℃),cellar(8～12℃) and normal(18～22℃) storage conditions for 110 days.

The results showed that theinhibition effect on potato soilless cultured plant growth was observed by spraying 20 mg/LPP_(333),the effect increased with the concentration of PP_(333) and not stopped up to 40 mg/L;theeffect however,on increasing the minituber yield was observed by spraying 30 mg/L PP_(333)and 35 mg/L PP_(333) had the best result.
