【摘要】 [Objective] The study was performed to explore more optimal breeding technology by the cutting propagation experiments of Sapindus mukorossi Gaertn. [Method] Cutting propagation experiments of Sapindus mukorossi Gaertn were carried out to investigate the rooting rate, root number and root length, and calculate and analyze the root index and root effective index by using orthogonal design method with the cuttings different in source, length and treatment. [Result] It was the best rooting performance by using about 15 cm long tip of branch as cuttings, and direct cuttage with the treatment of 200 mg/L ABT (1) rooting powder solution. Under these conditions, the rooting rate, root number and average root length were the best with the values of 92.3%, 18 and 17.3 cm in this experiment, respectively. The root effective index could reach 16.72 under the above conditions. [Conclusion] There was a better survival rate and rooting rate by using the tip of branches with keeping sharp and 15 cm long as cuttings.
