摘　　要：通过对翅果油树种子进行了适温处理、变温处理、激光处理、超声波处理、H2O2处理、PEG处理,对发芽实验进行研究,然后测定发芽率、发芽势、萌发指数、根长、芽长、株高、茎粗以及叶绿素含量。萌发实验的结果表明,变温预处理和PEG预处理能最有效地解除抑制物对种子萌发的影响,对种子进行变温处理和PEG处理是解除种子休眠和提高萌发率的有效途径。本实验为促进濒危植物翅果油树的种群繁衍以及对翅果油树的可持续利用提供一定的科学依据。A greenhouse experiment was conducted to study the effects of the proper temperature treatment, the changing temperature treatment, the laser treatment, the ultrasonic treatment, the H202 treatment, the PEG treatment on the germination of Elacagnus mollis Diels. Then germination rate, germination force, germination index, root length, bud length, plantheigh, stalkwidth and chlorophylls content were determined. The results showed that the seeds which were in changing temperature pretreatment, in the PEG pretreatment can effectively relieve the influence of inhibitor on the seed sprouts, therefore, these way is effective to break the seed dormancy and enhance the sprouting rate.
