Outline Activities
Business: Biotron Institute started in 1966 to furnish the biologists in Kyushu University with controlled environments and to promote environmental biology. The institute is composed of phytotrons, artificial light growth chambers for botanical research, zootrons, entomotrons and incubators for biotechnology, which are used by about three hundred biologists in the university for exact control of environmental factors of air temperature, humidity, wind, light and carbon dioxide gas concentration. The staff of the institute attend to management and maintenance of the facilities and equipment.

Research: Main title of research is "effects of environmental factors on root physiological function in plants". This study deals with (1) sensing of various environmental factors which may affect physiological status of plant roots, and (2) measurement of growth, respiration and uptake of water or nutrients (i.e., fundamental function of plant roots) under controlled environment.
Most of the material plants are horticultural crops, and they are grown in hydroponics or sand-ponics under controlled environment in a phytotron or an artificial light growth chamber. The root function responding to changes in the plant environment can be evaluated using various sensors and equipments. The results of this study could contribute to optimizing environment in horticultural crop production.

Education: The educatinal post is "Associate Professor, Environment Control for Biology, Department of Plant Resources, Graduate School of Bioresource and Bioenvironmental Sciences, Kyushu University".
