Winter-forcing culture of asparagus is becoming popular in Japan because the method can make production of asparagus possible during cold season whereas spring and summer-autumn harvest are still major product season.However, there are some problems such as, the color of the spear is pale, and rutin content is lower due to the low light intensity, especially in the production area which has much snow and short sunshine.The objective of this study was to investigate the effect of supplemental lighting on the yield, rutin content, sugar (fructose, glucose, sucrose), and spears color by using different irradiation time and different numbers of fluorescent lamp on the winter-forcing culture.Compared to the control plots, rutin content was significantly increased on the supplemental lighting plots.
