摘要
[目的]筛选木槿扦插最优条件。[方法]通过采用不同浓度ABT6号生根粉处理,比较不同枝龄木槿插穗的成活生根情况。[结果]插穗枝龄对生根率、根长、根数量的影响极显著。其中,采用3年生枝条、50 mg/kg ABT6号生根粉浸泡1 h后,扦插繁殖效果最理想,生根率达91.6%,根长5.8 cm,生根量60.3根。[结论]该研究可为木槿扦插繁殖提供科学依据。
[ Objective] To screen the optimal conditions of Hibiscus syriacus cuttings. [ Method] By using different concentrations of ABT6 rooting powder treatment,the survival rooting of different age cuttings of Hibiscus syriacus was compared. [ Result ] The effect of cutting age on rooting rate ,root length and rooting number was extremely significant. Among them,the 3 year old branches soaking with 50 mg/kg ABT6 rooting powder for 1 h, the best cutting propagation effect could be obtained,the rooting rate reached 91.6%, the root length of 5.8 cm, root number 60.3. [ Conclusion ] The study can provide scientific basis for the breeding of Hibiscus syriacus cuttings.
