| This experiment was carried out to figure out the $CO_2$ biomass and the growth response of Chinese cabbage and radish grown under the condition of high temperature and high $CO_2$ concentration to provide the information for the coming climatic change. Chinese cabbage and radish were cultivated in spring and autumn seasons under 4 treatments, 'ambient temp.+ambient $CO_2$ conc.', 'ambient temp.+elevated $CO_2$ conc.', 'elevated temp.+ ambient $CO_2$ conc.', and 'elevated temp. +elevated $CO_2$ conc.'. The 'elevated temp,' plot was maintained at 5 higher than 'ambient temp. (outside temperature)'and the 'elevated $CO_2$ cone.' plot was done in 650 ppm $CO_2$. The growth of spring-sown Chinese cabbage was worse than autumn-sown one, and was affected more by high temperature than high $CO_2$. concentration. The $CO_2$ biomass of Chinese cabbage was lower as 25.1-39.1 g/plant in spring-sown one than 54.8-63.4 g/plant of autumn-sown one. Daily $CO_2$2 fixation ability was not significantly different between spring- and autumn-sown Chinese cabbage as 1.9-2.9, 2.7-3.1 kg/10a/day, respectively. The $CO_2$ biomass of radish were 87.4-104.6 /plant in spring-sown one and 51.3$sim$76.4 g/plant in autumn-sown one. Daily $CO_2$ fixation ability of radish were 6.2-10.1 kg/10a/day in spring-sown one and 4.6-6.9 kg/10a/day in autumn-sown one. |
