Abstract: This report recommended a revised MS basal medium (macroelements were modified as follows: NH4NO3 850mg/L, KNO3 2000 mg/L, KH2PO4 100 mg/L, which is suitable for tissue culture of woody plants, by studying effects of three major nutrient elements (nitrogen, potassium and phosphorus) on the propagation in vitro of several woody plants (Cunninghamia lanceolata (Lamb.) Hook., Sequoia sempervirens (Lamb.) Lindl., etc.).Based on the data of the researches, the possibility in mass propagation in vitro of woody plants in particular those with difficulty for conventional propagation and some effective measures for increase of productivity and decrease of production cost were discussed.
