不同基质配方和NAA浓度对迷迭香扦插繁殖影响的研究（英文）

Effects of Different Matrix Formulations and NAA Concentrations on Rosemary Cuttings

[目的]研究不同基质配方和NAA浓度对迷迭香扦插苗根系生长和成活率的影响。[方法]采用随机区组试验,分别设计9个基质配方和5个梯度的NAA浓度,调查和测定数据采用Excel进行分析。[结果]处理7(草炭∶珍珠岩=3∶2)迷迭香扦插苗的根系生长最优,成活率最高为100%;NAA浓度150 mg/L时,迷迭香扦插苗的根系生长最优,成活率最高为88.9%。[结论]迷迭香扦插最适宜的基质配方为草炭∶珍珠岩=3∶2,最适宜的NAA浓度是150 mg/L。

[Objective] The effects of different matrix formulations and NAA concentra-tions on the growth of roots and survival rate of rosemary cuttings were investigat-ed. [Method] The randomized block design was adopted. There were 9 formulations of matrix and 4 concentrations of NAA in the test. The survey and determination data was analyzed by Excel. [Result] For rosemary cuttings, the roots of Treatment 7 （turfy soil∶perlite=3∶2） had the best growth with the highest survival rate of nearly 100%. The roots of rosemary cuttings had the best growth for 150 mg/L of NAA with the highest survival rate of 88.9%. [Conclusion] For rosemary cuttings, the op-timal matrix formulation was turfy soil∶perlite=3∶2, and the optimal NAA concentration was 150 mg/L.
