Measurement of the influence of acid rain on plant growth using statistical interferometry

In our laboratory, a highly sensitive interfeometric technique, Statistical Interferometry(STI), has been developed and used to monitor the growth behaviors of plant in connection with environmental conditions. The issue of acid rain is one of the serious environmental problems. The influence of the acid rain as an environmental condition on the growth of the plant is to be considered in the study. Some experiments to measure plant growth under an acid rain stress were performed using STI. As an experimental result, it was observed that temporal activation in the plant growth was followed by a slight deterioration of growth speed. The temporal activation was caused by the irrigation, and the latter effect was caused by the stress of acid rain.指導教員: 埼玉大学大学院理工学研究科准教授 門野博
