摘　　要：以桑寄生种子为试材,参考《国际种子检验规程》和《种子学》中种子发芽试验的方法,研究了不同发芽床、不同温度、不同光照、不同抑菌处理及不同批次等对种子发芽的影响。结果表明:种子最佳发芽床是纸床;不同温度处理种子发芽率之间差异显著,最佳发芽温度是25~30℃变温培养;光照对种子的萌发无影响;种子不消毒,用灭菌水处理效果最好;不同批次的种子质量有差异,春季的种子优于秋冬季的种子。In this study,reference to the seed germination experiment method of‘International Seed Inspection Procedures＇ and ‘Seed Science＇,the effects of different germination beds,different temperatures,different lights,different antibacterial treatments and different batches on seed germination were studied by using Taxillus chinensis seeds.Ther results showed that the seeds of the most suitable germination bed were paper beds;the difference of seed germination rate between different temperature treatments was significant,and the optimum germination temperature was 25-30 ℃;light had no effect on seed germination;seeds without disinfection,sterilization treatment with the best results.The quality of the seeds of different batches was different,and the spring seeds were better than autumn and winter seeds.
