This study investigated growth response of Korean exotic woody plants Acer saccharinum L. and Amorpha fruticosa L., on the climate change. We also examined the growth on nitrogen treatment of them. Acer saccharinum L. and Amorpha fruticosa L. were sown in March 2014 and then transplanted to each environment conditions in May 2015. Atmospheric conditions were divided into the outdoor environment treatment(AC-AT), the temperature elevation treatment(AC-ET), and the climate change treatment (EC-ET). In each atmospheric condition, non-treated (Control; C) pots were placed without nitrogen fertilizer treatment. Acer saccharinum L. treated 2g (N1), 20g (N2) of nitrogen fertilizer, respectively. And Amorpha fruticosa L. treated 1g (N1), 5g (N2) of nitrogen fertilizer, respectively. After the adaptation to each environmental condition until October 2016, the length, diameter of stem-root border, aboveground biomass, underground biomass, and leaves weight of Acer saccharinum L. and Amorpha fruticosa L. were measured. The above results show that Acer saccharinum L. was affected the length of shoot under conditions of increased temperature. Amorpha fruticosaL. means that When the nitrogen increases under the condition that the temperature and the CO2 concentration are increased together, the length of shoot and the Diameter of stem-root increase, but the Underground biomass decrease.
