| 摘 要： | 为提高新榛1号、新榛2号、新榛3号、新榛4号4个杂交榛树品种压条繁殖效率和商品苗率，分别用1000mg／LIBA、1250mg／LIBA、1500mg／LIBA、1000mg／LABT、1250mg／LABT、1500mg／LABT处理4个品种的榛树枝条。结果表明，杂交榛品种、生长素种类及浓度间的生根率、根数量、一级侧根根径存在显著性差异，一级侧根的根长无显著差异；4个杂交榛良种生根效果优劣排序为：新榛2号〉新榛1号〉新榛3号〉新榛4号；IBA的处理效果明显优于ABT；而不同浓度使用效果的排序为1250mg／L〉1000mg／L~1500mg／L；新榛1号、新榛2号、新榛3号采用1250mg／LIBA处理效果较好，而新榛4号用1000mg／LIBA处理效果最佳。

| Abstract: | The experiment was conducted to treat the four hybrid varieties of Xinzhen hazel layering,re- spectively using 1 000 mg/L IBA,1 250 mg/L IBA,1 500 mg/L IBA,1 000 mg/L ABT,1 250 mg/L ABT, 1 500 mg/L ABT in order to improve the layering reproduction effect and percentage of commorcial seed- lings of the four hazel varieties ： Xinzhen hazel 1, Xinzhen hazel 2, Xinzhen hazel 3, Xinzhen hazel 4. The re- sults indicated that there were significant differences of rooting rate, root quantity,level 1 lateral root diam- eter between hazel hybrid varieties with different type and concentration of hormone. There were no signif- icant differences between root length of level 1 lateral root. The sequence of good and bad rooting effect of the four improved hybrid varieties was as follows：Xinzhen hazel 2~Xinzhen hazel 1）Xinzhen hazel 3~ Xinzhen hazel 4;The treatment effect of IBA was significantly better than that of ABT;therefore,the se- quence of application effect of different concentration was as follows： 1 250 mg/L）l 000 mg/L）1 500 mg/L; The treatment effect of Xinzhen hazel 1 ,Xinzhen hazel 2 ,Xinzhen hazel 3 treated with 1 250 mg/L IBA was better. Therefore,the effect of Xinzhen hazel 4 treated with 1 000 mg/L IBA was the best. |
