Objective:
To solve the degradation of production and quality of Pinellia caused by the virus accumulation, rapid propagation technical of virus-free Pinellia was researched.
Methods:
Pinellia leaves,petioles as explants, technology of using high temperature (38 degrees C, 40d) and shoot tip culture producing virus-free Pinellia was explored.
Results:
The results showed that leaves without virus spots was about 88.9% when explants were culture for 40d at high temperature (38 degrees C). 1.0 mg/L 6-BA and 0.1 mg/L NAA could induce seedling from shoot tip,seedling rate is up to 91.4%; MS added 0.5 mg/L 6-BA and 0.1 mg/L NAA was conducive to growth of the plantlets; added 0.5 mg/L KT and 0.5 mg/L NAA was in favor of inducing root and promoting root growth, the survival rate of the transplanting seedling could reach 89.5%.
Conclusion:
A reliable system of virus-free Pinellia propagation is established.
