Thermo Luminescence Emission Systems for Stress Detection in Plants

Researchers are nowadays working on non-invasive, sensitive optical techniques to diagnose plants faster. Detecting stress symptoms in plants is essential to monitor the adverse effects in the environment. The scientists focus on validating some optical measurements to determine the pathological situations in stressed plants at the beginning stage. The techniques to be applied are based on biophysical ways such as thermo luminescence emission and chlorophyll fluorescence.

Thermo luminescence emission method can be used for stress detection in plants.  Plant ecosystem faces lots of problems such as toxic waste contamination, irregular climate changes and biotic stress factors. Additionally, industrial pollution, dehydration, and global warming also play a major role in affecting the plant eco systems and vegetation.  Photosynthesis is a physiological process that helps to determine plant productivity.

Thermo luminescence method facilitates physiological status and quantitative assessment of vegetation both in lab and field conditions. This method offers details about the photo system II reaction centres¡¯ energetic processes. Thermo luminescence emission from unfrozen leaves is known as ¡°afterglow emission¡± that have temperature of 45¢ªC. High-temperature thermo luminescence is a simple but efficient tool that can be used for monitoring oxidative stress in leaves.
