铁兰液体振荡培养再生与快速繁殖

Rapid Propagation of Tillandsia cyanea ‘Bert’ Through Liquid Shake Culture

以铁兰叶片为外植体,诱导获得脆性愈伤组织,液体振荡进行胚性愈伤组织培养及快速增殖,固体培养诱导胚状体萌发、不定芽生根,最后移栽成活,实现了铁兰的快速繁殖。在优化的培养条件下,铁兰无菌苗叶片愈伤组织诱导率90%以上,振荡后的愈伤组织100%成为胚状体,体积增殖系数可达5.0;90%以上的胚状体可分化为不定芽,95%以上的不定芽可诱导生根,移栽成活率95%以上。研究结果表明成功进行了铁兰的液体振荡培养及快速繁殖。

Using the leaf of Tillandsia cyanea as the explants, the fragile callus was induced. The rapid multiplication of embryonic callus was realized through liquid shake culture. In solid medium, the germination of the embryos and rooting of adventitious shoots were induced respectively. Rooting plantlets were transplanted and survived with high rates. In the optimized culture condition, the induction rate of callus was more than 90%. All the embryonic callus turned into embryos after liquid culture and the induction rate of the explants volume reached 5.0. More than 90% embryos developed into adventitious buds and 95% of the buds rooted after culture in solid medium. The transplanting survival rate was also more than 95%. These results indicated that the liquid oscillation and rapid propagation of T. cyanea was successful.
