 This research examine the effect of different concentrations of sucrose, kinetin, and benzylaminopurine on the formation of microtubers and potatoes grown in vitro. The results showed that the addition of sucrose, kinetin, or benzylaminopurine to the medium resulted in an increase in the number of microtubers larger than 5 millimeters when grown under short day conditions. Additionally, the addition of kinetin or benzylaminopurine to the medium resulted in an increase in the number of microtubers larger than 5 millimeters when grown under continuous dark conditions.
