摘要:
以白刺种子为试材，研究了低温层积和不同预处理方法对白刺种子发芽的影响。结果表明：低温层积+40%浓硫酸浸泡2 h的唐古特白刺种子的预处理效果最好，萌芽率为80％；低温层积3个月+刻伤处理效果次之，萌芽率为45％；常温放置萌芽率最低，仅为25％。此外，低温对不同白刺种类的种子萌发作用不同，低温层积处理唐古特白刺、泡果白刺和小果白刺的种子萌芽率依次是20%、27%、30%。
Abstract:
With seeds of Nitraria L. as materials,the methods of low temperature layer deposition and different pretreatments were researched in order to increase the seeds germination.The results showed that the highest seed germination rate (80%) was gotten by combination method of low temperature layer deposition and pretreatment (seeds soaked in 40% sulfuric acid for 2 hours) among 8 treatments.Following rate (45%) was obtained by treatment of low temperature layer deposition and pretreatment of carving seed capsule.The seed germination rate was the minimam (25%) under the room temperature in all treatments.Otherwise,effect of low temperature treatment was different on different species of Nitraria L..The seeds germination rates of Nitraria tangutorum Bobrov,Nitraria spaerocarpa Maxim,Nitraria sibirica  Pallas were 20%，27%，30% in turn.
