Plant stress poses a significant threat to global food security, driven by various environmental factors like drought, salinity, diseases, and nutritional imbalances. Traditional methods of assessing plant stress are often invasive, time-consuming, and lack temporal resolution. In contrast, nondestructive optical sensing emerges as a promising solution, allowing real-time data collection without disrupting the plant growth. We conducted experiments in a controlled indoor environment, employing red LED light sources and optical fibers to measure transmission of plants leaves. We explored plant stress induced by nutritional deficiency, water scarcity, intensity of white light and pathogen infection. The proposed nondestructive optical method detects early stress, demonstrating its potential for effective plant stress assessment and timely intervention ultimately enhancing agricultural productivity.
