Study on Tissue Culture of Neolamarckia cadamba

摘要: 对黄梁木组培快繁及规模化育苗技术进行了研究，结果表明：最适诱导培养基为MS＋6-BA 1.0 mg/L ＋IBA 0.1 mg/L＋GA₃2.0 mg/L；最佳增殖培养基为MS+6-BA 1.0 mg/L + IBA 0.05 mg/L，增殖系数达3.4以上；适宜的生根培养基为 MS+NAA 0.1 mg/L，15 d内生根率100%以上，平均根数为7.8条，平均根长为1.42 cm.

Abstract: Tissue culture techniques and large scale micropropagation of Neolamarckia cadamba were studied in this paper. The results showed that the optimal inducing medium was MS+6-BA 1.0 mg/L+IBA 0.1 mg/L＋GA₃2.0 mg/L; the optimal multiplication medium was MS +6-BA 1.0 mg/L + IBA 0.05 mg/L, the highest multiplication rate was 3.4. The optimal rooting medium was MS+NAA 0.1 mg/L. Within 15 d, the rooting rate could reach 100%, the average number of roots was 7.8, and the average length of roots was 1.42 cm.
