| 摘 要： | 以柠条锦鸡儿(Caragana korshinskii Kom.)无菌苗的子叶和下胚轴为外植体,研究其愈伤组织诱导及植株再生。结果表明:柠条锦鸡儿子叶和下胚轴均能诱导出愈伤组织,其适宜诱导培养基分别为M S+2,4-D2.0(mg/L)+KT0.1(mg/L)和M S+2,4-D2.0(mg/L)+BA0.5(mg/L);子叶诱导不定芽的适宜培养基为M S+6-BA0.2(mg/L)+NAA0.05(mg/L),下胚轴诱导不定芽的适宜培养基为MS+6-BA0.5(mg/L)+NAA0.05(mg/L);适宜生根培养基为1/2M S+IBA0.5(mg/L)+NAA0.5(mg/L)。本试验结果可为柠条锦鸡儿的快速繁殖利用及品种改良提供依据。

| Abstract: | A study on callus induction and plantlet regeneration of Horqin peashrub(Caragana korshinskii Kom.) was carried out.The results show that both the cotyledon and hypocotyl of the plant could successfully induce callus,for which the optimum media were MS 2,4-D 2.0(mg/L) KT 0.1(mg/L),and MS 2,4-D 2.0(mg/L) BA 0.5(mg/L),respectively.The best media for inducing adventitious buds by cotyledon and hypocotyl were MS 6-BA 0.2(mg/L) NAA 0.05(mg/L),and MS 6-BA 0.5(mg/L) NAA 0.05(mg/L),respectively,while the optimum rooting medium was 1/2MS IBA 0.5(mg/L) NAA 0.5(mg/L).Some suggestions for the rapid propagation and variety improvement of Caragana korshinskii are offered in this study. |
