[Objective]To optimize the seeds germinating conditions for Lamiophlamis rotata(Benth.) Kudo from Qinghai Province.[Method]The treating methods,temperature and illumination conditions were employed to design orthogonal test and the experimental data were analyzed by intuitive analysis and variance analysis.[Result]Temperature and treating method had very significant effects on germination rate and energy of Lamiophlamis rotata(Benth.) Kudo seeds.The influencing order of factors on the germination rate and germination energy were determined to be treating method of seeds >temperature >illumination condition and temperature > treating method of seed > illumination condition,individually.The optimal germinating condition for seeds of Lamiophlamis rotata(Benth.) Kudo was A1B1C2.That to say,the seeds pretreated with 50 mg/L GA for 24 h and cultivated in dark at 25 ℃ were the highest in germination rate and germination energy.[Conclusion]The germination rate of Lamiophlamis rotata(Benth.) Kudo seeds could be improved greatly under favorable temperature and pretreatments.
