Abstract
In order to develop the environmental control system based on plant responses, the bioelectric potential transition patterns on Spinach lamina in response to light-on were measured as an useful plant physiological information.
The obtained results are summarized as follows;
1. These bioelectric potential transition patterns were changed by air temperature, relative humidity, CO2 concentration, light intensity, plant growth and dying process.
2. One specific peak of this pattern was related with the rate of photosynthesis.
3. These transient pattern changes of bioelectric potential can be simulated by the exponential function.
4. Our study also suggests the possibility of expressing some relations between culture environmental conditions and growth conditions by means of function parameters.
