不同激素对甘草带芽茎段诱导丛生芽的影响

Effects of different hormones on induction of clustered buds from budded stems of Glycyrrhiza uralensis Fisch

采用单因素变量和不同激素组合设计,观察不同激素配比对甘草(Glycurrihiza uralensis Fisch.)带芽茎段诱导丛生芽的影响。结果表明,诱导丛生芽的最佳激素组合为MS+0.5 mg/L 6-BA+0.5 mg/L KT,其丛生芽的平均增值倍数达到(5.00±1.61)倍。适宜的激素配比有利于甘草带芽茎段诱导丛生芽,为甘草快速繁殖技术的应用提供理论和技术依据。

Single factor variable and different hormone combination design were used to observe the effect of different hormone ratio on the induction of clustered buds from the bud stem of Glycyrrhiza uralensis Fisch.The results showed that the best hormone combination for inducing cluster buds was MS+0.5 mg/L 6-BA+0.5 mg/L KT,and the average multiplication factor of cluster buds reached 5 times.Appropriate hormone ratio is beneficial to the induction of clustered buds from the budded stems of Glycyrrhiza uralensis Fisch,and provides theoretical and technical basis for the application of rapid propagation technology of Glycyrrhiza uralensis Fisch.
