不同消毒条件对白术种子萌发的影响研究

Influence of Different Sterilization Conditions on Atractylodes macrocephala Seed Germination

以白术(Atractylodes macrocephala)种子为实验材料,研究了不同消毒条件对白术种子萌发的影响。结果表明:随着Na Cl O浓度的增加,杀菌效果越来越好,但发芽率却越来越低。就本实验而言,先把白术种子在流水下冲2h,剥去种皮,再在流水下冲1h,之后用75%的酒精浸泡30s,最后用10%的Na Cl O溶液浸泡15min,效果最好。对于白术幼苗生长的影响,还有待于进一步的研究和总结。

Taking Atractylodes macrocephala seeds as experimental materials,the thesis studied the effects of differ？ent sterilization conditions on germination of Atractylodes macrocephala seeds. The experimental results show that：with the increasing of NaClO concentration,bactericidal effect is better,but the germination rate is lower. Therefore, in this experiment,firstly rinse the Atractylodes macrocephala seeds under running water for 2 hours,stripped off the seed coat,and then rinse them under running water for another 1 hour,then soak for 30 seconds with 75%alcohol, immersed in 10%NaClO solution for 15 mins,In this case,the effect is the best.The influence on Atractylodes macro？cephala seedlings growth still needs further study and conclusion.
