摘　　要：有齿鞘柄木为陕西省地方重点保护植物,具有优良的园林利用价值。为更好保护这一珍稀物种,通过L9(34)正交试验方法,研究不同的扦插基质、生长素、生长素浓度对有齿鞘柄木扦插生根能力的影响,结果表明,扦插基质是影响其生根的首要因素,其次是生长素,最后是生长素浓度;以珍珠岩为扦插基质,选用ABT为生长素,200mg/L的处理组合,生根效果最好,生根率能够达到96.7%,生根指数达408.0。Toricellia angulata var.intermedia with value of landscaping is protected in Shaanxi Province.The cutting propagation technology of Toricellia angulata var.intermedia was studied with L 9（3 4） orthogonal test design which consisted of three factors of cutting medium,auxin and the auxin concentration.The results showed that cutting medium had the main impact on rooting,and then was the type of auxin,auxin concentration had the least impact.Taking perlite as the cutting medium,ABT as hormone,200 mg/L as auxin concentration were the best cutting propagation technical conditions of Toricellia angulata var.intermedia,and the rooting rate reached 96.7%,the rooting index reached 408.0.
