Background : Recent climate change has also affected the biological season for plants. There are various studies on this, but most of them are studying horticultural crops. The purpose of this study was to investigate the timing of flowering in different regions and to predict the flowering time of Schisandra chinensis (Turcz.) Baillon. using meteorological data. Methods and Results : The flowering time and cultivation area of Schisandra chinensis were searched and surveyed by the Internet data and Annual research report of the RDA. Accumulated temperature and Growing degree day at 0℃, 5℃, 10℃ or more and Cumulative hours of sunshine at 0℃ or more to the cultivation area and flowering period of irradiated Schisandra chinensis were calculated from meteorological data of KMA (Korea. Meteorological Administration) and calculated using Excel, respectively. statistical analysis was performed using Excel. The data collected were 15 research reports and 20 internet surveys, but it was difficult to use statistical significance due to the high coefficient of variation. The 5-year Suwon data and the 3-year data of Jinan were used in the study report data relatively close to the meteorological stations. Conclusion : Results of statistical analysis. The flowering time of Schisandra chinensis is the time when Accumulated temperature of 0℃ or more [Σ (daily average temperature > 0℃)] becomes 650℃ and the Growing degree day of 0℃ or more { Σ [ (day maximum temperature + day minimum temperature) / 2 > 0℃ ] } was 670℃. The coefficient of variation was 6.5% and 6.2%, respectively.
