| 摘 要： | 以菊芋带芽点的薯盘及带节的幼嫩茎段为外植体,MS为基本培养基,附加不同种类和浓度的生长调节物质,研究菊芋组织培养和快速繁殖的技术环节,最终筛选出最优技术参数组合,建立菊芋再生体系。试验结果表明：茎段外植体是理想的快速繁殖材料,正接（形态学下端向下）是最佳的接种方式。芽诱导最佳培养基为MS＋1.0mg·L-16-BA＋0.2mg·L-1IBA,诱导率为95%;继代增殖最适宜培养基为MS＋2.0mg·L-16-BA;壮苗培养最佳培养基为MS＋0.1mg·L-16-BA;生根适宜培养基为MS＋0.2mg·L-1NAA,生根率达100%;移栽成活率达95%,大田种植成活率达95%以上。

| Abstract: | Helianthus tuberosus（Jerusalem artichoke） tubers with sprout and shoots with a section of these young stem segments were taken as explants,and were cultured on MS basic medium with several plant growth regulating substances in different concentrations.The technology of tissue culture and rapid propagation on Jerusalem artichoke was researched,and finally filtered out the best combination of technical parameters to establish Jerusalem artichoke regeneration system.The results showed that the optimal explants material for rapid propagation were shoots,positive inoculation（morphology lower down） was the optimal inoculation method.The optimal shoot induction medium was MS＋1.0 mg·L-1 6-BA ＋0.2 mg·L-1 IBA with the induction rate of 95%.The optimal subculture medium was MS＋2.0 mg·L-1 6-BA,the optimal strong seedling medium was MS＋0.1 mg·L-1 6-BA.The optimal rooting medium was MS＋0.2 mg·L-1 NAA,the rooting rate reached 100%,transplant survival rate of 95%,field planting survival rate of 95%. |
