Abstract: The effects of exogenous hormone on maintaining of virus\|free potato plantlets and the combined effects of medium, temperature and photoperiod on microtuber induction were studied. The results showed that the optimal medium of maintaining plantlets was MS+CCC 40 mg·L-1+6\|BA 05 mg·L-1+GA3 005 mg·L-1,the optimal media to induce microtubers was MS+6\|BA 60 mg·L-1+sugar 60 g·L-1+active carbon 3 g·L-1, temperature at 18℃, and brightness for 10 h·d-1.

Key words: potato plantlets, maintaining, microtuber, optimization
