Environment control in an artificial light growth chamber for simulating a specific climate of a lowland rice field at a local area in Japan

In a lowland rice field at the end of a rainy season (early summer) in Japan, it is suggested that drastic change in the climate could cause symptom of rice leaf chlorosis and blight without a pathogen. For reproducing the symptom and investigating its process, daily changes in air temperature, relative humidity, wind velocity and light intensity were simulated using an artificial light growth chamber in Biotron Institute, Kyushu University. The exact control in the growth chamber enabled the simulation of environmental procedure causing the disease of rice plants, and the investigation could be useful for the disease prevention.
