| Abstract: | Seeds morphology and germination of Potentilla chinensis are studied in this paper.The results show that the seeds are oblate,palm-brown or black-brown,and have clear and irregular veins.The weight is 0.449 g per thousand-granule.The seed viability is 83.25%.The optimum temperature for seed germination is 25 ℃,the average germination rate is 50.67%.The seeds should be soaked in hot water at 40 ℃ for 20 min,after that,the germination rate can reach to 68.67%.The germination rate can reach to 70% after being soaked in 200 mg/L GA. |
