摘　　要：试验在对单粒黑果枸杞(Lycium ruthenicum Murr.)花青素测定的基础上,以黑果枸杞无菌苗为外植体,利用响应面设计Design-Expert软件就激素浓度及C源组合对诱导响应率、愈伤诱导率及植株形成率的影响进行了研究。结果表明,诱导及愈伤诱导的最佳条件为6-BA 0.92 mg/L、NAA 0.45 mg/L、C源组合蔗糖为2.26%;而植株形成率的最佳条件为6-BA 1.15 mg/L、NAA 0.38 mg/L、C源组合蔗糖2.93%。愈伤诱导过程中碳源组合与激素间存在较强的互作,组织切片所采取的诱导途径可能是胚状体再生途径,RAPD检验显示后代的变异率低,表明利用该繁殖体所培育的幼苗后代可维持母系的优良性状。In present experiment,based on the measurement of anthocyanins content in single dried berry,the aseptic leaves derived from the sterile seedlings of L.ruthenicum Murr.which germinated on MS medium were used as explants,and optimization condition of hormone concentration and C source combination was selected for response frequency,callus inducing frequency and plantlet forming frequency using the response surface design Design-Expert software.The results showed that the best condition for response frequency and callus induction frequency was 6-BA 0.92 mg/L,NAA 0.45 mg/L,and C source for sucrose 2.26%,respectively;And best condition for plantlet formation frequency was 6-BA 1.15 mg/L,NAA 0.38 mg/L,and C source sucrose 2.93%,respectively.Result also showed that there was a strong interaction between the carbon source combination and hormones during the callus induction process.Tissue sections showed that the the way for plantlet forming induction or shoot regeneration adopted in the experiment may be the somatic embryogenesis,and RAPD test of the offspring regeneration obtained in present showed extremely low rate of variation which suggested the excellent characteristic of mother plant would maintain in descendant derived from this propagation system.
