摘要
药王茶经济价值较高,可用于发展林下经济。利用3种外源激素,采用正交设计L_(9)(3^(4))开展药王茶扦插试验。结果表明,药王茶扦插成活最佳措施为NAA浓度150 mg/L溶液浸泡插穗60 min,成活率80.0%,平均生根数量6.77条;生根最佳措施为ABT1浓度50 mg/L溶液浸泡插穗30 min,平均生根数量8.16条/株,成活率73.33%。成活最佳措施可在药王茶扦插育苗生产中推广应用;生根最佳措施可用于注重根系数量的扦插育苗。
Dasiphora fruticosa had high economic value and could be used to develop the understory economy.Using 3 exogenous hormones,an orthogonal design L_(9)(3^(4))was used to conduct a cutting experiment on Dasiphora fruticosa.The results showed that the best measure for the cuttings survival was soaking the cuttings with 150 mg/L NAA solution 60min.The survival rate was 80.0%and the average number of roots was 6.77.The best rooting measure was soaking the cuttings with ABT1 concentration of 50 mg/L for 30 min.The average rooting number was 8.16/plant,and the survival rate was 73.33%.The best measures of survival can be applied in the cutting seedling production of medicinal king tea.The best measures for rooting can be used for the cuttage breeding which focuses on the number of roots.
