Abstract: The effects of kinds, concentration, treatment time of plant growth regulator on rooting rate, root coefficient and seedling height of Semiliquidambar cathayesis were studied by orthogonal design method. The effects of different cutting matrix and different cutting processing on S. cathayesis also carried out. The results showed that 200 mg稬-1 ABT1 treating for 30 min and in a matrix with a layer 2 cm river sand and overlying a layer 2 cm yellow soil were best for S. cathayesis cutting, the average rooting rate was up to 90.3%, the average root coefficient and average seedling height were the best. The primary and secondary factors were matrix type > growth regulator type > growth regulator concentration > processing time. The growth indexs of cuttings from 6 cm semi lignified twigs with cutting double surfaces were the best.
