STRESS DETECTION IN PLANTS
The experiments carried out in these case studies measure the plant’s stress level when put under potentially damaging conditions. Each plant was exposed to different circumstances: fire, chlorine, hydrochloric acid, boiling water, drought and root absorption of vinegar. Plants always emit fluorescence, but when a plant is under stressful conditions the fluorescent emittance increases. This fluorescence is invisible to the human eye. If we could see beyond our limited visible spectrum, plants would appear to us as glowing organisms, directly responsive to their environment.
