Abstract:	In this study the effect of potassium nutrition on the induction and development of microtubers by in vitro tuberization was evaluated for two potato genotypes: Christian and Desiree. The objective of this experience was to investigate whether an increasing in potassium concentration would improve in vitro tuberization rate. It was studied the effect of three levels of potassium (10, 25 and 40 (mM/L) on in vitro tuberization. Increasing the potassium supply increased the size but decreased the number of microtubers.
