Effects of Different Treatments on Rooting and Germination of Paeonia rockii T. Hong et J. J. Li Seeds

摘要

[Objectives] This study was conducted to investigate the effects of different treatments on rooting and germination of Paeonia rockii T. Hong et J. J. Li seeds.[Methods] Different stratification time and temperatures and different GA 3 concentrations and treatment time were set to screen the optimum treatment method for promoting seed rooting and germination.[Results] The rooting rate was the highest when the seeds were subjected to 30d of stratification treatment in an incubator at 25℃, and treated with 300mg/L GA3 for 24h. Soaking the seeds with 300 mg/L GA3 for 24 h combined with 30d of stratification treatment was most beneficial to germination, and the germination rate was over 90%.[Conclusions] This study provides technical guidance and basic information for the rooting and germination of P. rockii seeds.
