厚皮香全光照弥雾扦插技术研究

Study on Cutting Propagation Technique of Ternstoremia gymnathea Under Full-illumination and Mist

以厚皮香1 a生嫩枝为材料,采用三因素(激素、处理浓度、处理时间)三水平正交实验设计,对影响厚皮香扦插生根的相关因子进行综合分析。结果表明:NAA 200 mg/L浸泡1 h的处理组合为最佳处理组合,生根率达40%;激素、处理浓度对厚皮香扦插生根率影响差异显著,外源激素是影响厚皮香扦插生根的主要因子,处理浓度是影响扦插生根的第二因素,浸泡时间是影响扦插生根的最次因素。

The relevant factors which affects the cutting rootage of Ternstoremia gymnathea were comprehensively analysed.Orthogonal experiment design with three factors（hormones,concentration,handle time） and three levels were applied for the study,using 1 year old branches under full-illumination and mist condition.The result showed that Ternstoremia gymnathea was difficult to rooting.Among the combinations,the rooting rate for cut propagation would reach as high as 40%.According to result of range and variance analysis,the optimum combination for cutting rootage was adding NAA 200 mg/L to dip 1 hour.Using different hormones and different concentration made obviously effect in cutting rootage of Ternstoremia gymnathea.The results indicated that the major factor affecting the rooting rate was hormones,the sub major factor was concentration;while handle time had little influence.
