The experiment was conducted to study the effect of growth regulators BA, K, IAA, and NAA at a concentration 5 mg L-1 for each of them on the ability of plantlets with / without shoot tip for two potato cultivars (Emma and Buree) to tuber formation.

The numbers of microtubers (Tuber/ Jar), diameter and weight were calculated after incubated at 16-18 ºC with dark for 90 days.

The results showed that the significant effect of shoot tip on the production of microtubers, which was reflected in the phenotypic characteristics of the microtubers.

Plantlets with shoot tip of Emma cultivar cultured in medium at 5mgL-1 NAA significant superior in the number, diameter, and weight of microtubers (3.50 Microtuber Plantlets-1 , 0.77 cm, and 0.66 g Respectively), compared with plantlets without shoot tip of the same cultivar which gave the lowest number of microtubers, diameter and weight (0.58 Microtuber Plantlets -1 , 0.17 cm and 0.05 g Respectively) when cultured at 5 mg l-1 BA
