摘　　要：Effects of treating with 0.05, 0.10, 0.20 and 0.40 mg·g-1 NAA for 3 h on cutting regeneration of Disanthus cercidifolius var. longipes H.T.Chang were studied. The results indicated that effects of different concentrations of NAA on biological indexes of cutting regeneration weremarkedly different except plantheight and ground diameter.With0.1 mg·g-1 NAA solution treating for 3 h, individual biomass, root biomass, total length of root, root number, new leaf number and total length of new branch increased obviously.Effects of treating with 0.05, 0.10, 0.20 and 0.40 mg·g^-1 NAA for 3 h on cutting regeneration of Disanthus cercidifolius var. longipes H.
