双色花叶芋(Caladium bieolor)和亮白花叶芋(C.hortulanum)的叶及花序外植体在加有2,4-D 和激动素或只加有2,4-D 的培养基上产生了愈伤组织,它们在转移到无激素或含激动素和低浓度生长素的培养基上以后分化出大量胚状体,并进一步长成小植株。本工作为花叶芋的快速繁殖提供了方法。 Leaf and inflorescence explants of Caladium bieolor and C. hortulanum were cultured on medium supplemented with 2,4-D and kinetin or with 2,4-D alone Callus was generated, which, after being transferred to hormone-free or medium containing kinetin and low concentrations of auxin, differentiated into large numbers of embryoid bodies and further grew into plantlets. This work provides a method for the rapid propagation of Artichoke.
