The substrate treatments include peat soil, yellowsoil, river sand and vermiculite, adopting with a randomized complete block design. The hormone treatments adopted L9(33)orthogonal design with different hormone kinds(NAA, IBA and ABT), concentrations(500, 1 000 and 1 500 mg·L-1), and treating time(10 s, 1 min and 30 min). The results showed that:(1)The mixed substrate of peat soil+vermiculite(1:1, volume ratio) was the best, with the rooting rate of 81.81%, mean rooting number of 20.33 per plant, the average root length of 4.80 cm, and the root effective index of 3.05; (2)The hormone kinds had the greatest influence on cutting effectiveness of C.tabularis young shoots among the three main factors, followed by hormone concentrations, and the treating time had the least influence. In cutting, under the mixed substrate of peat soil+vermiculite(1:1), treated ewith ABT1 of 1 000 mg·L-1 for 10 s, the rooting effective was the best. %U https://bbr.nefu.edu.cn/EN/10.7525/j.issn.1673-5102.2019.03.008
