| 摘 要： | 以陈山红心杉20个红心比例达70%以上的优良无性系基部萌条为外植体,建立了组培高效繁育体系。优化条件筛选结果表明:MS BA2.0mg/L(单位下同) NAA0.5为最佳诱导培养基;1/2MS BA1.5 NAA0.5 适量有机物为最佳增殖培养基,苗木叶色嫩绿,生长正常,增殖系数可达4.5;1/2MS NAA0.2 IBA0.5为最佳生根培养基,生根率达89.3%。

| Abstract: | The tissue culture and rapid propagation system of Cunninghamia lanceolata (Chenshan-red-fir)were established, based of basal branches of fine clones for twenty materials, which are above 70% on red-heart proportion. The result showed: the culture medium of induced budding was optimum based on MS BA2.0mg/L NAA0.5; the culture medium of multiplication was optimum based on 1/2MS BA1.5 NAA0.5 right amount organic matter, in which the leaves grow green and fine, and the multiplication averagely reached about 4.5 times; the rooted culture medium is optimum based on 1/2MS NAA0.2 IBA0.5, and the rooting ratio can be up to 89.3%. |
