研究了不同浓度叠氮化钠和诱变时间处理对香蕉主栽品种‘巴西蕉’不定芽的诱变效果。结果表明,2.31 mmol/L叠氮化钠处理3 h和3.08 mmol/L叠氮化钠处理2 h为‘巴西蕉’不定芽诱变的适宜处理组合,在这2个诱变条件下,‘巴西蕉’不定芽致死率接近半致死率,存活的不定芽能够恢复生长和增殖,容易获得再生植株。 The effects of different concentrations of sodium azide and mutagenic time on the adventitious buds of banana ’adventitious buds’ were studied. The results showed that the treatment of 2.31 mmol / L sodium azide for 3 h and 3.08 mmol / L sodium azide for 2 h was the suitable treatment combination for the adventitious bud mutation of ’Banana plantain’. Under these two mutagenesis conditions, Brazil banana ’adventitious buds near the lethality rate of semi-lethal adventitious buds to restore growth and proliferation, easy access to regenerated plants.
