Abstract:
Through germination test of the seeds of Acanthopanax giraldii on stratification of different temperature conditions，different treatment concentration of GA3and different habitats seeds,the effects of seed embryo growth and germination rate on different stratification methods were studied.The results showed that the seed of Acanthopanax giraldii after its picking could completed embryo after-ripening growth，alse called seed morphological after-ripening after high temperature of 18℃ around 90 d stratification treatment process；It was still in depth dormancy after the seed embryo’s morphological after-ripening，and germination process could be completed under the temperature of 4℃ with 90 days.A certain concentration of GA3was good for the forming of seed embryo in high temperature conditions of 18℃，as well as the increasing of forming rate of seed embryo and germination rate.The seeds of Acanthopanax giraldii germination rate were significant difference at different habitats.
