Abstract: Effec s of different N＋ implantation doses on the germination vigor,germination rate and survival seedling rate of Cyclamen Persicum Mill.The results showed that the germinationvigor and rate of Persicum Mill seeds showed the trend of declining rising declining with the increasing of N＋ implantation does,which displayed a peculiar＂saddle＂shape.The survival seedling rate was close to germination rate at low dose,but obviously decreased at high dose.
