Abstract

Abstract: Both peat plus vermiculite double layer substrate culture and channel aeroponics were adopted in the study of tuberizing characteristics and minituber yield potential of virus2free (VF) potato plantlets in the same
growing season. Trial results of the number and weight distribution of VF minituber indicated that , within 70-day growing period , stolons , total swelled minituber by substrate culture were 15 and 5. 7 respectively , while data obtained from aeroponics were 97 and 76 accordingly. The latter were 6. 5 fold and 13. 3 fold of the former separately. Comparing with substrate culture , aeroponics significantly improve the minituber propagation
coefficient .

Key words: Potato, Virus2free minituber, Channel aeroponics, Yield
