白纹竹芋的组织培养

TISSUE CULTURE OF MARANTA ARUNDINACEAVAR.VARIEGATA

本文报道了用组织培养技术繁效白纹竹芋,促进侧芽增生的方法,以白纹竹芋的根状茎为外植体,在MS培养基上诱导侧芽生长,再将新生芽转移至MS+BA6+NAA 0.5的培养基中进行继代培养,可获得大量不定芽并形成再生植株.培养过程中未发生愈伤组织,再生植株易于生根,幼苗种植成活率很高.

Rhizoma of Maranta arundinaceae var. variegata are cultured in modified Murashige and Skoog medium supplemented with 6-benzylamino purin (BA) 1 and naphthalene acetic acid (NAA) 0.1 mg/liter. Through about 3 weeks rhizoma lateral buds are induced germination. When lateral bud shoots as inocula subcultuted in MS media supplemented three kinds cytokinin,ef- fects of them are compared. Experiment indicats, for clonal increase, that the best results can be obtained when inocula are cultured in medium containing zeatin 4 and NAA 0.5 mg/liter.
