中文摘要：
探讨了6－苄氨基嘌呤（6－BA）、吲哚乙酸（IAA）、萘乙酸（NAA）、吲哚丁酸（IBA）等植物生长调节剂对土人参种子萌发及幼苗早期生长的影响。结果表明：不同植物生长调节剂对土人参种子发芽和幼苗生长的影响不同，同一植物生长调节剂的浓度不同其影响也不同。与ck对比，6-BA促进土人参种子发芽与幼苗生长的最佳浓度为2mg／L；IAA、NAA和IBA的最佳浓度分别为50、100、50mg／L。其中，2mg／L的6-BA对土人参种子发芽的促进效果最好；50mg／L的IAA促进土人参幼苗生长的效果最明显。
英文摘要：
Effects of plant growth regulator on both Talinm paniculatum seed germination and its seedling growth at the early phase were examined. Talinm paniculatum were treated with different concentration of 6-g amino purine （6-BA） , naphthyl acetic acid （ IAA）, indoles acetic acid （NAA） and indolebutyric acid （IBA） in a series of experiments. The results showed that different plant growth regulator and even different concentra- tion of the same kind have different influences on Talinm paniculatum seed germination and its seedling growth. Compared with ek, the optimal concentration for 6-BA, IAA, NAA and IBA to promote the seed germi- nation of Talinm paniculatum and its seedling growth are respectively 2 mg/L, 50,100 mg/L and 50 mg/L. Above all ,6-BA of 2 mg/L has best effect for promotion of the germination of Talinm paniculatum while IAA of 50 mg/L facilitates its seedling growth most evidently.
