Abstract
Changing environmental conditions can affect plant growth by influencing water and nutrient transport and photosynthesis. Plant physiological responses under changing environmental conditions can be non-destructively monitored using electrodes as plant induced electrical signal (PIES). Objective of the study was to monitor PIES in response to increased CO 2 and decreased photosynthetic photon flux density (PPFD). The PIES increased during day time when transpiration and photosynthesis occurs and monitored CO 2 concentration was negatively correlated to the PIES. Enhanced CO 2 concentration slightly reduced PIES, but the effect of increased CO 2 was limited by light intensity. The effect of reduced PPFD was not appeared immediately because water and nutrient transport was not promptly affected by the light. The study was conducted to evaluate short-term effect of increasing CO 2 and decreasing PPFD, hence proline content and chlorophyll fluorescence was not significantly affected by the conditions.
