黑果枸杞的多倍体诱导研究（英文）

Study on the Polyploid Induction of Lycium ruthenicum Murr.

该试验以黑果枸杞组培苗顶端叶片为试材,以秋水仙素作为诱变剂,采用施入法,对黑果枸杞进行多倍体诱导,通过染色体计数法鉴定出4株多倍体植株。结果表明,秋水仙素浓度为300 mg/L,处理时间为7天及21天的组合;秋水仙素浓度为400 mg/L,处理时间为14天的组合;秋水仙素浓度为500 mg/L,处理时间7天的组合均成功诱导出四倍体植株。

With apical leaves of Lycium ruthenicum Murr as experimental material, the polyploids of L. ruthenicum were induced with colchicine solution, and total four polyploidy plants were identified by chromosome courts. The results showed that tetraploid plants of L. ruthenicum were successfully induced with 300 mg/L of colchicine solution after 7 and 21 d of induction, with 400 mg/L of colchicine solution after 14 days of induction, and with 500 mg/L of colchicine solution after 7 days of induction, respectively.
