PlantECG is an innovative system for non-invasive monitoring of plant physiological status using chlorophyll fluorescence analysis. It represents a breakthrough in plant health diagnostics, enabling the detection of stress in plants within seconds—like an "EKG" for plants.
Core Technology: The system analyzes OJIP (Chlorophyll fluorescence induction kinetics) to assess plant vitality and stress conditions without damaging the plant.
The PlantECG Analyzer processes fluorescence data collected from the PlantECG fluorymeter device. For instructions on using the device itself, see the Device Guide.
PlantECG builds on decades of chlorophyll fluorescence research pioneered by the late Prof. Reto J. Strasser. Prof. Kalaji has developed novel approaches to monitor plant physiological status by analyzing how plants respond to light stress through fluorescence emission patterns.
The OJIP parameters calculated by this analyzer include important metrics such as:
Prof. Kalaji has established himself as one of the world's foremost experts in chlorophyll fluorescence research. His scientific contributions include:
Ryszard Grodowski is the inventor and creator of the sensor device that powers PlantECG technology.
Prof. Kalaji has also showcased patented antiviral moss-based filters and plant-derived antivirals at EXPO 2025 in Osaka, Japan, demonstrating the broad applications of plant science innovation.
