摘要:

为探索沙滩黄芩扦插繁殖的最佳ABT生根粉浓度，以沙滩黄芩枝条为材料，研究不同浓度生根粉1号和生根粉2号对沙滩黄芩扦插生根的影响。结果表明：未用生根粉处理的沙滩黄芩没有生根迹象；相同浓度下，生根粉2号的生根效果优于生根粉1号。其中，生根粉2号150 mg?kg^-1处理最好，生根率达到82.67%，生根数达到31.67条，平均根长达到3.38 cm。生根粉1号100 mg?kg^-1处理生根率达到62.67%，生根数达到25条，平均根长达到2.62 cm。

Abstract:

In order to explore the suitable concentration of Scutellaria strigillosa with cutting propagation，taking branches of Scutellaria strigillosa?as test materials,the effect of different concentrations of ABT₁?and ABT₂ on root growth of?Scutellaria strigillosa?were studied.The results showed that the control without soaking ABT had not got root.The rooting effect of ABT₂?was better than ABT₁?with the same concentration.When the concentration of ABT₂?was 150 mg?kg^-1，rooting rate reached to 82.67%，root number was 31.67，average root length was 3.38 cm in the treatment with soaking 100 mg?kg^-1ABT₁，rooting rate was 62.67%,root number was 25,average rooting length was 2.62 cm.
