The present study was made to investigate effect of CO2 application to strawberry cv. "Echigo-hime" for green house forcing culture in Niigata region, that the climate condition is low temperature and low amount of solar radiation in winter. Experiment was conducted from autumn 2004 till spring 2005 in Niigata University Shindoori Station. CO2 gas was applied from sunrise for 5 hours, and the average concentration was about 1,500 cm3m(-3), in the period in Jan. to Mar. in a.m. Leaf color CO2 treated plants was higher than the control, due to the active NO3-N absorption. And total yield increased about 17% compared with the control. CO2 treated plants had much harvest of big fruits of 20g or more. The sugar content (Brix) of fruits was higher about 1.0-3.5 degrees by CO2 treatment. Conclusion, CO2 application to strawberry was effective technique in that winter conditions as Niigata region.
