Abstract

Abstract: Rapid induced the root and branches by hydroponics technique, with different concentrations of NAA and nutrient solution to treat the branches of Schefflera octophylla （Lour.） Harms, and the optimal concentration of NAA and nutrient solution for its root growth were obtained by means of experimental statistics and variance analysis, namely the optimal concentration of NAA was 15 mg/L, the optimal concentration of nutrient solution was 200~300 mg/L（about 1/4 of mother liquid）. After induced successful, the roots and branches were most developed when nutrient solution concentration was 500~600 mg/L（about 1/2 of mother liquid）. So, the same hormone and the same nutrient solution on the Schefflera octophylla （Lour.） Harms varied greatly at the different concentration.

Key words: Schefflera octophylla （Lour.） Harms, hydroponic, NAA, nutrient solution
