Developing Monitoring System for Plant Physiological Activity in plant factory

植物工厂使高效栽培的人工条件变为实用化。为了发现更有效的培养条件，监测植物活动是必要的。其中，光照条件是影响植物生长的最重要因素。在本研究中，我们测量了不同类型辐照下植物的生物电势和CO2消耗。结果表明，闪烁照射下的生物电势响应随光合速率的变化具有不同的行为和强度。我们认为可以通过测量生物电势来评价闪烁照射下的光合反应。在植物工厂中，生物电势测量将成为植物控制农业环境的有效方法。

Plant factory which make artificial condition for efficient cultivation become practical use. Monitoring plant activity is necessary in order to detect more effective cultural conditions. Especially, the light irradiation condition is the most important factor for plant growth. In this study, we measured the bioelectric potential and CO2 consumption of plants under various types of the irradiation. This result showed that the bioelectric potential responses under the blinking irradiation have various behaviors and intensity of the response related to photosynthetic rate. We conclude that photosynthetic reaction under the blinking irradiation can be evaluated by measurement of the bioelectric potential. And we also suggested that the bioelectric potential measurement become useful method for agro-environment control by plant in plant factories.
