甘蔗品种127—78在添加5mg2、4－D和18％椰子水的Payan培养基上离体培养获得的愈伤组织，经7种不同剂量问．00％～0．06％）α—溴萘处理，进行分化，对叶绿素的变化、诱变剂在分化中的作用。植株的大小和致死剂量进行评估。结果表明，随着诱变剂浓度增加，植株变小，致死时间? Sugarcane Varieties 127-78 The callus obtained was ex-vivo cultured on Payan medium supplemented with 5 mg 2,4-D and 18% coconut water at seven different doses. 00% ~ 0.06%) α-bromonaphthalene treatment, differentiation, changes in chlorophyll, the role of mutagens in differentiation. Plant size and lethal dose were assessed. The results showed that as the concentration of mutagen increased, the plants became smaller and the lethal time decreased.
